What is Fibonacci Retracement?
Definition
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.
Detailed Explanation
Fibonacci retracement levels are derived from the Fibonacci sequence where each number is the sum of the two preceding numbers (1, 1, 2, 3, 5, 8, 13, 21...). The key ratios emerge from the mathematical relationships between these numbers: 61.8% (any number divided by the next), 38.2% (any number divided by the number two places ahead), and 23.6% (any number divided by the number three places ahead).
To draw Fibonacci retracements, traders identify a significant price swing from low to high (or high to low) and apply the ratio levels. During an uptrend pullback, the retracement levels act as potential support. A stock that rallied from $80 to $100 might find support at the 38.2% level ($92.36), the 50% level ($90), or the 61.8% level ($87.64).
The 61.8% retracement is considered the golden ratio and is watched by the most traders. Pullbacks that hold at or above this level are considered healthy corrections within an uptrend. Pullbacks that exceed 78.6% often indicate the prior trend has reversed. The 50% level, while not a true Fibonacci ratio, is included because of its psychological significance.
Fibonacci extensions (beyond 100%) are used to project price targets after a breakout. The 161.8% extension is the most common target level. Confluence of multiple Fibonacci levels from different swing points, combined with other technical indicators, creates high-probability trading zones.
Example
A stock rallies from $50 to $100. The 38.2% retracement is $80.90, the 50% is $75.00, and the 61.8% is $69.10. If the pullback finds support at $75 with bullish RSI divergence, it is a potential buying opportunity.

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.
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.
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.
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.
