Trend Following with Moving Average Envelope — Simple Mechanical System

r/investingstocksDaily (long-term trend following)by reddit_community

MA Envelope (20 SMA ± 2.5%): buy above upper band, sell below lower band. Mechanical system. Slightly trails in bulls but massively outperforms in bears.

ENTRY RULES

Calculate 20-day SMA and 2.5% envelope bands | Buy when price closes above upper envelope | This means price has enough momentum to break out | Stay invested until exit signal | Use end-of-day data only (no intraday noise)

EXIT RULES

Sell when price closes below lower envelope | Move to cash (T-bills/money market) | Re-enter only on new buy signal above upper envelope | No stop loss needed — the lower envelope IS the stop | Maximum time in cash: unlimited (system decides)

Trend Following with Moving Average Envelope — Simple Mechanical System

Moving Average Envelope strategy: calculate 20 SMA, then add/subtract 2.5% for the upper and lower bands. Buy when price closes above upper band (breakout strength). Sell when price closes below lower band (breakdown). Simple, mechanical, no discretion needed. Backtested on SPY over 20 years: slightly underperforms buy-and-hold in bull markets but massively outperforms in bear markets by getting you to cash.
