Mean Reversion Trading: Buy Low, Sell High Automatically

What is Mean Reversion?

Mean reversion is based on a simple idea: prices tend to return to their average over time.

When a stock drops significantly below its average, it's likely to bounce back. When it rises far above average, it's likely to pull back. This creates predictable trading opportunities.

Why Mean Reversion Works

Markets overreact to news and emotions. Fear causes overselling, greed causes overbuying. Mean reversion strategies profit from these overreactions by:

• Buying fear - When everyone is selling
• Selling greed - When everyone is buying

Best Assets for Mean Reversion

Works Well:

• SPY, QQQ - Large, liquid ETFs mean revert reliably
• Blue chips - AAPL, MSFT, JPM tend to bounce from oversold

• Small caps - Can stay oversold for long periods
• Meme stocks - Irrational moves don't follow patterns

Mean Reversion vs Momentum

| Mean Reversion | Momentum |

|----------------|----------|

| Buy low, sell high | Buy high, sell higher |

| Works in ranges | Works in trends |

| RSI below 30 = buy | RSI above 50 = buy |

| Counter-trend | With-trend |

| Higher win rate | Bigger wins |

Pro tip: Use both! Mean reversion in ranging markets, momentum in trending markets.

Risk Management for Mean Reversion

The Danger: Catching Falling Knives

Sometimes "oversold" stocks keep falling. A stock down 50% can drop another 50%.

Protection:

• Always use stop losses - 3-5% below entry
• Don't fight the trend - Avoid mean reversion in strong downtrends
• Scale in - Buy 1/3 position at first signal, add if it drops more
• Set time limits - Exit after 5-10 days if no bounce
