What is Moving Average?
Definition
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.
Detailed Explanation
The two main types are the Simple Moving Average (SMA), which gives equal weight to all periods, and the Exponential Moving Average (EMA), which gives more weight to recent prices.
The most commonly used are the 50-day and 200-day SMAs. When the 50-day crosses above the 200-day, it is called a 'golden cross' (bullish). When it crosses below, it is called a 'death cross' (bearish).
Moving averages help identify trend direction, act as dynamic support and resistance levels, and help with entries and exits.
Moving averages are lagging indicators. They work best in trending markets and can generate false signals in choppy conditions. Many traders combine them with other indicators for confirmation.
Formula
Simple Moving Average (SMA) = Sum of Closing Prices over N periods / N
Exponential Moving Average (EMA) = (Current Price x Multiplier) + (Previous EMA x (1 - Multiplier))
Multiplier = 2 / (N + 1)Example
A 50-day SMA is calculated by adding the last 50 daily closing prices and dividing by 50. If the stock price ($155) crosses above its 50-day SMA ($150), some traders interpret this as a bullish signal.
