Mean reversion is based on the statistical observation that prices tend to return to their average over time. When a stock moves too far above its average (overbought), it tends to pull back. When it moves too far below (oversold), it tends to bounce. This strategy is the opposite of trend following — you buy weakness and sell strength, betting that extreme moves are temporary and the "mean" will reassert itself.
Identifying mean reversion opportunities: (1) RSI below 30 (oversold) or above 70 (overbought). (2) Price touching or exceeding Bollinger Band extremes. (3) Price significantly below the 20-day or 50-day moving average. (4) ADX below 20 (indicating a range-bound market where mean reversion thrives). (5) Large gap downs in fundamentally sound stocks. The ideal setup combines multiple oversold signals at once.
Oversold bounce strategy: When a stock with strong fundamentals drops to oversold levels (RSI below 30, price at lower Bollinger Band, high-volume selling climax), it often represents a buying opportunity. Entry: Wait for a confirming candle (hammer, bullish engulfing, or simply a close above the prior day's high). Target: The 20-day moving average or the middle Bollinger Band. Stop: Below the recent low. This strategy has high win rates (60-70%) but smaller gains per trade.
Overbought fade strategy: When a stock rallies sharply into overbought territory without fundamental justification, it often pulls back. Entry: Look for a bearish candle after RSI exceeds 80, especially if price is well above the upper Bollinger Band. Target: The 20-day moving average. Stop: Above the recent high. This strategy is riskier than oversold bounces because trends can sustain overbought conditions longer than expected.
When mean reversion works and when it fails: Mean reversion works best in range-bound, choppy markets where no strong trend exists (ADX below 20). It FAILS catastrophically when a genuine trend develops — buying a falling stock in a strong downtrend ("catching a falling knife") can result in massive losses. The key filter: ONLY apply mean reversion when the stock is in an overall uptrend (above 200-day SMA) and the dip is a temporary pullback within that trend.
Risk management for mean reversion: (1) Use tight stops — if the "mean reversion" turns out to be a trend change, exit quickly. (2) Scale into positions: buy 1/3 at RSI 30, another 1/3 at RSI 25, final 1/3 at RSI 20. (3) Set a maximum drawdown per trade (e.g., 3-5%) — if the stock keeps falling past your stop, do not add more. (4) Diversify across multiple mean reversion trades to reduce the impact of the one that turns into a trend break.
Mean reversion in the Egyptian market: Egyptian stocks can become temporarily oversold due to sector-wide selling, panic from political or economic news, or forced selling by margin calls. These events often create mean reversion opportunities in fundamentally strong stocks. FoudaLens's BUY_PULLBACK signal is essentially a mean reversion signal — it identifies stocks in uptrends that have pulled back to attractive levels. Focus on liquid stocks to ensure you can exit if the trade moves against you. This is not financial advice.
