AI Intelligence
AI Sentiment Divergence
The gap between standard market sentiment (headlines) and deep-layer AI analysis of management tone, linguistic cues, and regulatory filing risks.
Hallucination Mitigation
The technical process of ensuring an AI model does not generate false or misleading financial data by implementing strict grounding and cross-verification layers.
Pulse Score
The StoxPulse Pulse Score is a proprietary composite metric (0-100) that rates a stock's overall health across five dimensions: Value, Growth, Health, Momentum, and Sentiment. Each dimension is scored 0-20, and the total determines a letter grade from A+ to F.

RAG is an AI framework that grounds large language models (LLMs) in external, verifiable data sources—such as SEC filings—to prevent hallucinations and ensure financial accuracy.
Corporate Finance
Cost of Equity
Cost of equity is the return that investors require for holding a company's stock. It represents the opportunity cost of investing in a particular stock versus a risk-free alternative and is a key component of WACC calculations.
Earnings Call
An earnings call is a conference call held by a public company's management after releasing quarterly or annual financial results. It typically features prepared remarks from the CEO and CFO followed by a question-and-answer session with Wall Street analysts.
Earnings Surprise
An earnings surprise occurs when a company's reported earnings per share differs from the consensus estimate of Wall Street analysts. A positive surprise (beat) typically lifts the stock price, while a negative surprise (miss) usually causes a decline.
Forward Guidance
Forward guidance is the projection or forecast that a company's management provides about expected future financial performance. Typically shared during earnings calls, it includes estimates for revenue, earnings, margins, and other key metrics for upcoming quarters or the full year.
Merger and Acquisition (M&A)
Mergers and acquisitions are corporate transactions where companies combine (merger) or one company purchases another (acquisition). M&A is used to achieve growth, gain market share, acquire technology, realize synergies, or enter new markets.
Reverse Stock Split
A reverse stock split consolidates multiple shares into fewer shares at a proportionally higher price. For example, a 1-for-10 reverse split converts 10 shares at $1 into 1 share at $10. It is typically viewed as a negative signal.
Secondary Offering
A secondary offering is the sale of new or existing shares by a company that is already publicly traded. It allows companies to raise additional capital or enables insiders to sell their holdings. Secondary offerings often pressure the stock price due to dilution.
Spin-off
A spin-off occurs when a company creates a new independent publicly traded company by distributing shares of a subsidiary or division to existing shareholders. It allows each entity to focus on its core business and often unlocks hidden value.
Weighted Average Cost of Capital (WACC)
WACC is the average rate of return a company must earn on its existing assets to satisfy all capital providers—both equity holders and debt holders. It is used as the discount rate in DCF valuations and reflects the blended cost of all financing sources.
Derivatives
Call Option
A call option gives the holder the right, but not the obligation, to buy a specified number of shares at a predetermined price (strike price) before a specific expiration date. Investors buy calls when they expect the stock price to rise, as calls increase in value as the underlying stock appreciates.
Call Option
A call option gives the buyer the right to purchase the underlying asset at the strike price before expiration. Calls are used when an investor expects the price to rise. The maximum loss for the buyer is the premium paid.
Covered Call
A covered call is an options strategy where an investor holding shares of a stock sells call options against those shares to generate income from the premium collected. It is one of the most popular and conservative options strategies, trading some upside potential for immediate income.
Expiration Date
The expiration date is the last day an option contract is valid. After this date, the option ceases to exist. Options with more time until expiration are more valuable because there is more time for the underlying to move favorably.
Futures Contract
A futures contract is a standardized agreement to buy or sell an asset at a predetermined price on a specific future date. Unlike options, futures obligate both parties to complete the transaction. They are used for hedging, speculation, and price discovery.
Greeks (Delta, Gamma, Theta, Vega)
The Greeks are mathematical values that measure different dimensions of risk in options positions. Delta measures directional sensitivity, gamma measures delta's rate of change, theta measures time decay, and vega measures volatility sensitivity.
Implied Volatility (IV)
Implied volatility is the market's forecast of the likely magnitude of a stock's price movement, derived from option prices. High IV means options are expensive because the market expects large price swings, while low IV means options are cheap because calm conditions are expected.
Options
Options are financial contracts that give the buyer the right, but not the obligation, to buy (call) or sell (put) an underlying asset at a specified price (strike) before a specified date (expiration). They are used for speculation, hedging, and income generation.
Options Expiration
Options expiration is the date on which an option contract becomes void and the right to buy or sell the underlying asset ceases to exist. Standard monthly options expire on the third Friday of each month, while weekly options expire every Friday.
Options Greeks
The Options Greeks are mathematical measures of an option's sensitivity to various factors: Delta (price movement), Gamma (delta's rate of change), Theta (time decay), Vega (volatility changes), and Rho (interest rates). They are essential tools for managing options risk.
Options Premium
The options premium is the price paid by the buyer to the seller for an option contract. It consists of intrinsic value (how much the option is in-the-money) and extrinsic value (time value plus volatility value). The premium represents the maximum loss for option buyers and maximum gain for option sellers.
Put Option
A put option gives the holder the right, but not the obligation, to sell a specified number of shares at a predetermined strike price before expiration. Investors buy puts when they expect a stock price to decline or want to protect an existing stock position from downside risk.
Put Option
A put option gives the buyer the right to sell the underlying asset at the strike price before expiration. Puts are used when an investor expects the price to fall or wants to protect against downside risk in existing holdings.
Strike Price
The strike price (or exercise price) is the predetermined price at which an option holder can buy (for calls) or sell (for puts) the underlying asset. It is the most important factor in determining an option's value and risk/reward profile.
Fixed Income
Bond
A bond is a fixed-income security where the investor lends money to an issuer (government or corporation) for a defined period at a fixed or variable interest rate. Bonds pay periodic interest (coupons) and return the principal at maturity.
Bond Yield
Bond yield is the return an investor earns from holding a bond, expressed as an annual percentage. The most common measure is yield to maturity (YTM), which accounts for the bond's coupon payments, price, par value, and time remaining until maturity.
Coupon Rate
The coupon rate is the annual interest rate paid by a bond's issuer relative to the bond's face value. A bond with a $1,000 face value and 5% coupon pays $50 per year in interest, typically in semiannual installments.
Credit Rating
A credit rating is an assessment by a rating agency (S&P, Moody's, Fitch) of a borrower's ability to repay debt. Ratings range from AAA (highest quality) to D (default), with investment grade (BBB- or above) and speculative grade (BB+ or below) as the key dividing line.
Duration
Duration measures a bond's sensitivity to interest rate changes, expressed in years. A duration of 5 means the bond's price will change approximately 5% for every 1% change in interest rates. Longer duration means more interest rate risk.
Junk Bond
Junk bonds, also called high-yield bonds, are corporate bonds rated below investment grade (BB+ or lower). They offer higher interest rates to compensate investors for the elevated risk of default compared to investment-grade bonds.
Junk Bonds (High-Yield Bonds)
Junk bonds, officially called high-yield bonds, are debt securities rated below investment grade (BB+ or lower by S&P). They offer higher yields to compensate investors for greater default risk and are issued by companies with weaker financial profiles or higher leverage.
Municipal Bond
Municipal bonds (munis) are debt securities issued by state and local governments to fund public projects. Their primary advantage is that interest income is typically exempt from federal income tax, and often from state and local taxes for in-state residents.
Treasury Bonds
Treasury bonds (T-bonds) are long-term debt securities issued by the U.S. government with maturities of 20 or 30 years. They are considered the safest investment available, backed by the full faith and credit of the U.S. government, and serve as the global benchmark for risk-free returns.
Treasury Securities
Treasury securities are debt instruments issued by the US government to fund federal spending. They are considered the safest investments in the world and serve as the benchmark for all other interest rates. Types include bills, notes, and bonds.
Yield Curve
The yield curve is a graph plotting bond yields across different maturities, from short-term (3 months) to long-term (30 years). A normal curve slopes upward, an inverted curve slopes downward, and inversions have preceded every U.S. recession since 1955.
Yield to Maturity (YTM)
Yield to maturity is the total return anticipated on a bond if held until it matures, expressed as an annual percentage. It accounts for the bond's current price, coupon payments, face value, and time to maturity, making it the most comprehensive bond yield measure.

8-K Filing
An 8-K is a current report filed with the SEC to announce major events that shareholders should know about. It is filed on an as-needed basis whenever material events occur, such as acquisitions, executive changes, or significant financial developments.
Asset Turnover
Asset turnover measures how efficiently a company uses its total assets to generate revenue. It is calculated by dividing revenue by total assets and indicates how many dollars of sales each dollar of assets produces.
Book Value
Book value is the net asset value of a company, calculated as total assets minus total liabilities from the balance sheet. It represents the theoretical amount shareholders would receive if the company liquidated all assets and paid off all debts.

Free cash flow (FCF) is the cash a company generates from its operations after accounting for capital expenditures needed to maintain or expand its asset base. It represents the cash available for dividends, debt repayment, buybacks, and acquisitions.
Gross Margin
Gross margin is the percentage of revenue remaining after subtracting the cost of goods sold (COGS). It measures how efficiently a company produces its products or delivers its services and is a key indicator of pricing power and production efficiency.
Inventory Turnover
Inventory turnover measures how many times a company sells and replaces its inventory during a period. A higher turnover indicates efficient inventory management and strong demand, while low turnover may signal overstocking or weak sales.
Market Capitalization
Market capitalization (market cap) is the total market value of a company's outstanding shares of stock. Calculated by multiplying the share price by the total number of shares, it represents the market's consensus valuation of a company's equity.
Net Income
Net income, also called the bottom line or net profit, is the total profit remaining after all expenses, taxes, interest, and costs have been deducted from revenue. It is the final line on the income statement and represents the profit available to common shareholders.
Operating Income
Operating income, also called operating profit or EBIT, measures the profit a company earns from its core business operations after deducting operating expenses. It excludes income and expenses from non-operating activities like interest, taxes, and one-time items.
Operating Margin
Operating margin is the percentage of revenue that remains as operating profit after deducting all operating costs. It measures how efficiently a company converts revenue into profit from its core business operations, excluding the effects of financing and taxes.
Profit Margin
Profit margin measures the percentage of revenue that becomes profit after expenses. It comes in several forms — gross margin, operating margin, and net margin — each measuring profitability at a different stage of the income statement.
Quick Ratio (Acid Test)
The quick ratio, also known as the acid-test ratio, measures a company's ability to meet short-term obligations using only its most liquid assets. It excludes inventory from current assets, providing a more conservative view of liquidity than the current ratio.
Return on Assets (ROA)
Return on Assets (ROA) measures how effectively a company uses its assets to generate profit, calculated by dividing net income by total assets. It shows how many cents of profit a company earns for each dollar of assets it controls.
Return on Equity (ROE)
Return on Equity (ROE) measures how effectively a company uses shareholder equity to generate profits. Expressed as a percentage, it divides net income by shareholders' equity and is a key indicator of management efficiency and business quality.
Return on Invested Capital (ROIC)
Return on Invested Capital (ROIC) measures how effectively a company generates profit from the capital invested in its business. It is widely considered the best single metric for assessing a company's quality and competitive advantage.
Revenue
Revenue, also called sales or top line, is the total amount of money a company earns from selling its products or services before any expenses are deducted. It is the first line item on the income statement and the starting point for profitability analysis.
Revenue Growth Rate
Revenue growth rate measures the percentage increase in a company's revenue over a specific period, typically year-over-year or quarter-over-quarter. It is a primary indicator of business momentum and a key factor in stock valuation.
SEC Filing
SEC filings are regulatory documents that public companies must submit to the Securities and Exchange Commission. These filings provide transparency into a company's financial health, operations, and governance, ensuring investors have access to material information.
Shares Outstanding
Shares outstanding represents the total number of a company's stock shares currently held by all shareholders, including institutional investors, insiders, and the public. It is a key input for calculating metrics like EPS, market capitalization, and ownership percentages.
Working Capital
Working capital is the difference between a company's current assets and current liabilities. It measures a company's short-term liquidity and operational efficiency, indicating whether it has enough resources to cover its near-term obligations.
Macroeconomics
Consumer Price Index (CPI)
The Consumer Price Index (CPI) measures the average change in prices paid by urban consumers for a basket of goods and services including food, housing, transportation, healthcare, and recreation. It is the most widely followed measure of inflation in the United States.
Consumer Price Index (CPI)
The Consumer Price Index measures the average change in prices paid by urban consumers for a basket of goods and services. It is the most widely reported inflation measure and a key input for monetary policy, Social Security adjustments, and financial market expectations.
Federal Funds Rate
The federal funds rate is the interest rate at which banks lend reserve balances to each other overnight, set as a target range by the Federal Reserve's FOMC. It is the most influential interest rate in the world, affecting everything from mortgage rates to stock valuations to global capital flows.
Gross Domestic Product (GDP)
Gross Domestic Product (GDP) is the total monetary value of all goods and services produced within a country's borders during a specific period. It is the broadest measure of economic activity and the primary gauge of an economy's size and health.
Inflation
Inflation is the rate at which the general level of prices for goods and services rises over time, eroding purchasing power. Moderate inflation (around 2%) is considered healthy for economic growth, while high inflation can destabilize economies and financial markets.
Inflation Rate
The inflation rate measures the percentage increase in the general price level of goods and services over a period, typically 12 months. It erodes purchasing power and is a critical factor in monetary policy decisions, bond yields, and stock valuations.
Quantitative Easing (QE)
Quantitative Easing is an unconventional monetary policy tool where a central bank purchases government bonds and other securities from the open market to inject money into the financial system, lower long-term interest rates, and stimulate economic activity when conventional rate cuts are insufficient.
Trade Balance
The trade balance is the difference between a country's exports and imports of goods and services. A trade surplus (exports exceed imports) adds to GDP, while a trade deficit (imports exceed exports) subtracts from it. The U.S. has run persistent trade deficits since the 1970s.
Unemployment Rate
The unemployment rate is the percentage of the labor force that is jobless and actively seeking employment. Published monthly by the Bureau of Labor Statistics, it is a key indicator of economic health and influences Fed monetary policy decisions.
Market Mechanics
After-Hours Trading
After-hours trading occurs outside regular market hours (9:30 AM - 4:00 PM ET), including pre-market (4:00-9:30 AM) and post-market (4:00-8:00 PM) sessions. It allows investors to react to earnings reports, news events, and developments that occur outside regular hours.
Bear Market
A bear market is a period of sustained declining prices in a financial market, typically defined as a drop of 20% or more from a recent peak. It is characterized by widespread pessimism, economic contraction, declining corporate earnings, and increased selling activity.
Bid-Ask Spread
The bid-ask spread is the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask) for a security. It represents a transaction cost for traders and is a key indicator of market liquidity.
Bull Market
A bull market is a period of sustained rising prices in a financial market, typically defined as a gain of 20% or more from a recent low. It is characterized by investor optimism, economic growth, strong corporate earnings, and increasing buying activity.
Circuit Breaker
Circuit breakers are mechanisms that temporarily halt trading on an exchange when prices decline by specified percentages. They are designed to prevent panic selling, provide time for information to disseminate, and restore orderly market conditions.
Dark Pool
A dark pool is a private exchange or forum for trading securities where orders are not displayed to the public before execution. They allow large institutional investors to trade large blocks of shares without revealing their intentions to the broader market and moving prices against them.
High-Frequency Trading (HFT)
High-frequency trading uses powerful computers and algorithms to execute a large number of trades at extremely high speeds, often in microseconds. HFT firms profit from tiny price discrepancies and represent a significant portion of daily trading volume.
Initial Public Offering (IPO)
An Initial Public Offering (IPO) is the process by which a private company offers shares to the public for the first time, becoming a publicly traded company. IPOs allow companies to raise capital from public investors and provide early investors and founders with liquidity.
Insider Trading
Insider trading refers to buying or selling a company's stock by individuals with access to material nonpublic information. Legal insider trading occurs when corporate insiders trade and properly report it; illegal insider trading involves trading on confidential information.
Limit Order
A limit order is an instruction to buy or sell a security at a specified price or better. Buy limit orders execute at or below the limit price; sell limit orders execute at or above it. It guarantees price but not execution.
Margin Trading
Margin trading involves borrowing money from a broker to purchase securities, using the purchased securities as collateral. It amplifies both gains and losses, allowing investors to control larger positions than their cash alone would permit.
Market Depth
Market depth shows the quantity of buy and sell orders at various price levels for a security. It reveals the supply and demand landscape beyond just the best bid and ask, indicating how much a large order would move the price.
Market Maker
A market maker is a firm or individual that continuously quotes both buy (bid) and sell (ask) prices for a security, profiting from the bid-ask spread while providing liquidity to the market. They ensure that buyers and sellers can always execute trades promptly.
Market Order
A market order is an instruction to buy or sell a security immediately at the best available current price. It guarantees execution but not the exact price, making it the fastest but least price-controlled order type.
Market Order vs Limit Order
A market order executes immediately at the best available price, guaranteeing execution but not price. A limit order specifies a maximum buy price or minimum sell price, guaranteeing price but not execution. These are the two fundamental order types in stock trading.
Sector Rotation
Sector rotation is an investment strategy that involves moving capital between stock market sectors based on the economic cycle, relative performance, or changing market conditions. Different sectors tend to outperform at different stages of the business cycle.
Share Buyback
A share buyback (or stock repurchase) occurs when a company uses its cash to buy back its own shares from the market, reducing the number of shares outstanding. Buybacks return capital to shareholders by increasing the value of remaining shares and boosting per-share metrics like EPS.
Short Interest
Short interest is the total number of shares of a stock that have been sold short by investors but not yet covered or closed out. It indicates bearish sentiment and is reported as a number of shares or as a percentage of the total float.
Short Selling
Short selling is the practice of borrowing shares from a broker and selling them at the current price, with the intention of buying them back later at a lower price for a profit. It allows investors to profit from declining stock prices but carries theoretically unlimited risk.
Stock Split
A stock split increases the number of shares outstanding while proportionally reducing the price per share, leaving the total market capitalization unchanged. Companies typically split their stock when the share price becomes too high for retail investors, improving accessibility and liquidity.
Stop Loss
A stop loss is an order placed with a broker to sell a security when it reaches a specified price, designed to limit an investor's loss on a position. It automates risk management by ensuring positions are closed before losses become excessive.
Volume
Volume is the total number of shares or contracts traded in a security during a given period, typically a single trading day. It measures the intensity of trading activity and is a key indicator of market interest, liquidity, and the strength of price movements.
Risk Management
Alpha
Alpha measures the excess return of an investment relative to a benchmark index after adjusting for risk. Positive alpha indicates outperformance; negative alpha indicates underperformance. It is the ultimate measure of an investment manager's skill.
Asset Allocation
Asset allocation is the process of dividing an investment portfolio among different asset categories — stocks, bonds, cash, real estate, and alternatives — based on an investor's goals, risk tolerance, and time horizon. Studies show asset allocation decisions explain over 90% of portfolio return variability.
Beta
Beta measures a stock's volatility relative to the overall market. A beta of 1.0 means the stock moves in line with the market. A beta above 1.0 indicates higher volatility than the market, while a beta below 1.0 indicates lower volatility.
Correlation
Correlation measures the degree to which two assets move in relation to each other, ranging from +1 (perfect positive correlation) to -1 (perfect negative correlation). It is fundamental to portfolio diversification and risk management.
Diversification
Diversification is the risk management strategy of spreading investments across different assets, sectors, geographies, and asset classes to reduce the impact of any single investment's poor performance. It is often called the only free lunch in investing because it can reduce risk without necessarily reducing expected returns.
Dollar-Cost Averaging (DCA)
Dollar-cost averaging is an investment strategy where a fixed dollar amount is invested at regular intervals regardless of the asset's price. This approach automatically buys more shares when prices are low and fewer when prices are high, reducing the average cost per share over time.
Drawdown
A drawdown measures the peak-to-trough decline in the value of a portfolio or investment before a new peak is established. It quantifies the maximum loss an investor experienced during a specific period and is a key measure of downside risk.
Hedging
Hedging is an investment strategy designed to reduce the risk of adverse price movements in an asset. It typically involves taking an offsetting position in a related security, such as options, futures, or inverse ETFs.
Index Fund
An index fund is a type of mutual fund or ETF designed to track the performance of a specific market index, such as the S&P 500, by holding all or a representative sample of the securities in that index. They offer broad diversification, low costs, and have consistently outperformed most actively managed funds.
Maximum Drawdown
Maximum drawdown (MDD) measures the largest peak-to-trough decline in an investment's value before a new peak is reached. It quantifies the worst-case loss an investor would have experienced and is a critical metric for assessing downside risk and emotional tolerance.
Rebalancing
Rebalancing is the process of realigning a portfolio's asset allocation back to its target weights by selling overweight positions and buying underweight positions. It is a disciplined approach that maintains the intended risk level and can enhance returns through systematic buy-low, sell-high behavior.
Sharpe Ratio
The Sharpe Ratio measures the risk-adjusted return of an investment by calculating excess return per unit of volatility. Developed by Nobel laureate William Sharpe, it allows investors to compare the return of different investments relative to the risk taken to achieve those returns.
Standard Deviation
Standard deviation measures the dispersion of returns around the average return. In investing, it quantifies volatility—a higher standard deviation means returns vary more widely, indicating greater risk and uncertainty.
Value at Risk (VaR)
Value at Risk (VaR) estimates the maximum expected loss of an investment portfolio over a specific time period at a given confidence level. For example, a 1-day 95% VaR of $1 million means there is a 95% probability that the portfolio will not lose more than $1 million in a single day.
Volatility
Volatility measures the degree of variation in a stock's price over time. Higher volatility means larger and more frequent price swings, indicating greater uncertainty and risk. It is commonly expressed as the annualized standard deviation of returns.
Technical Analysis
Average True Range (ATR)
Average True Range is a volatility indicator that measures the average range of price movement over a specified period, accounting for gaps. It is used for position sizing, stop-loss placement, and assessing market volatility.
Bollinger Bands
Bollinger Bands are a technical analysis tool consisting of a middle band (20-period SMA) and two outer bands set at two standard deviations above and below the middle band. They dynamically adjust to volatility, widening during volatile periods and narrowing during calm periods.
Breakout
A breakout occurs when a stock's price moves above a resistance level or below a support level with increased volume. Breakouts signal that the balance of supply and demand has shifted and often lead to sustained price moves in the direction of the break.
Candlestick Patterns
Candlestick patterns are visual formations created by one or more candlestick bars on a price chart that traders use to predict future price movements. Each candlestick shows the open, high, low, and close for a period, with the body color indicating whether the close was above or below the open.
Cup and Handle
The cup and handle is a bullish chart pattern that resembles a tea cup. The cup forms as a U-shaped consolidation, and the handle is a small downward drift before a breakout. It signals a continuation of an uptrend.
Death Cross
A death cross occurs when the 50-day simple moving average crosses below the 200-day simple moving average. It is considered a bearish technical signal suggesting potential for continued downward price movement and has preceded several major market declines.
Double Bottom
A double bottom is a bullish reversal chart pattern that forms when a stock declines to a support level twice with a moderate rally in between, creating a W-shaped formation. A break above the middle peak confirms the pattern and signals a potential trend reversal.
Fibonacci Retracement
Fibonacci retracement uses horizontal lines at key Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, and 78.6%) to identify potential support and resistance levels during a price pullback. The 61.8% level, known as the golden ratio, is considered the most significant.
Golden Cross
A golden cross occurs when a short-term moving average (typically the 50-day SMA) crosses above a long-term moving average (typically the 200-day SMA). It is widely regarded as a bullish technical signal indicating potential for sustained upward price movement.
Head and Shoulders
Head and Shoulders is a chart pattern consisting of three peaks — a higher middle peak (the head) flanked by two lower peaks (the shoulders). It is one of the most reliable reversal patterns in technical analysis, signaling a potential shift from an uptrend to a downtrend.
Ichimoku Cloud
The Ichimoku Cloud is a comprehensive technical indicator that defines support and resistance, identifies trend direction, gauges momentum, and provides trading signals—all in a single chart overlay.
MACD (Moving Average Convergence Divergence)
MACD is a trend-following momentum indicator that shows the relationship between two exponential moving averages of price. It generates signals through crossovers of the MACD line and signal line, zero-line crossovers, and divergences with price.
Moving Average
A moving average is a technical indicator that smooths price data by calculating the average price over a specific number of periods. It helps identify trends, support and resistance levels, and potential buy or sell signals by filtering out short-term price noise.
On-Balance Volume (OBV)
On-Balance Volume is a momentum indicator that uses volume flow to predict changes in stock price. It adds volume on up days and subtracts volume on down days, creating a cumulative total that reflects buying and selling pressure.
Relative Strength Index (RSI)
The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of recent price changes on a scale of 0 to 100. Readings above 70 typically indicate overbought conditions, while readings below 30 suggest oversold conditions.
Stochastic Oscillator
The stochastic oscillator is a momentum indicator that compares a stock's closing price to its price range over a specified period. It oscillates between 0 and 100, identifying overbought conditions above 80 and oversold conditions below 20.
Support and Resistance
Support and resistance are price levels where a stock historically tends to stop falling (support) or stop rising (resistance). These levels form because of concentrated buying or selling interest and are foundational concepts in technical analysis.
Trend Line
A trend line is a straight line drawn on a chart connecting two or more price points that defines the direction and speed of a trend. Uptrend lines connect rising lows, downtrend lines connect falling highs, and breaks of established trend lines signal potential trend changes.
Valuation
Discounted Cash Flow (DCF)
Discounted Cash Flow (DCF) is a valuation method that estimates the present value of an investment based on its expected future cash flows. It is considered one of the most theoretically sound valuation approaches because it values a company based on the actual cash it generates.
Discounted Cash Flow (DCF)
Discounted Cash Flow is a valuation method that estimates the present value of an investment based on its expected future cash flows. It is considered one of the most rigorous approaches to determining a company's intrinsic value.
Dividend Yield
Dividend yield is a financial ratio that shows how much a company pays in dividends each year relative to its stock price. Expressed as a percentage, it helps income-focused investors compare the cash return of dividend-paying stocks.
Earnings Yield
Earnings yield is the inverse of the P/E ratio, calculated as earnings per share divided by the stock price, expressed as a percentage. It allows direct comparison between stock returns and bond yields, making it useful for cross-asset valuation decisions.
Enterprise Value (EV)
Enterprise Value (EV) represents the total value of a company, including both equity and debt, minus cash. It is the theoretical takeover price of a company and provides a more complete picture of a company's worth than market capitalization alone.
EV/EBITDA
EV/EBITDA is a valuation ratio that compares a company's enterprise value to its earnings before interest, taxes, depreciation, and amortization. It is one of the most widely used multiples for comparing valuations across companies and is the standard metric in M&A transactions.
Fair Value
Fair value is the estimated rational price of a stock or asset based on objective analysis of fundamentals, growth prospects, and comparable valuations. It represents the price at which an informed buyer and seller would agree to transact in an arm's-length transaction.
Intrinsic Value
Intrinsic value is the estimated true worth of a company or asset based on fundamental analysis, independent of its current market price. When the market price is below intrinsic value, value investors consider the stock undervalued and a potential buying opportunity.
PEG Ratio
The PEG Ratio (Price/Earnings-to-Growth) adjusts the P/E ratio by dividing it by the expected earnings growth rate. It helps investors determine whether a stock's valuation is justified by its growth prospects, with a PEG of 1.0 generally considered fair value.
Price-to-Book Ratio (P/B)
The Price-to-Book ratio (P/B) compares a company's market capitalization to its book value. It shows how much investors are paying for each dollar of net assets and is particularly useful for valuing financial companies, asset-heavy businesses, and distressed companies.
Price-to-Earnings Ratio (P/E)
The Price-to-Earnings Ratio (P/E) compares a company's current stock price to its earnings per share. It indicates how much investors are willing to pay for each dollar of earnings, making it one of the most common valuation metrics in stock analysis.
Price-to-Free-Cash-Flow (P/FCF)
The Price-to-Free-Cash-Flow ratio compares a company's market price to the free cash flow it generates per share. It is favored by many investors over P/E because free cash flow is harder to manipulate than accounting earnings and represents actual cash available to shareholders.
