24.3 points behind buy and hold after costs; lost money on the unseen years.
20/50 EMA cross · NIFTY 50 stocks
It returned +47.5% in total over the test, after costs; buying and holding over the same period returned +71.8%, 24.3 points more. It lost money on the years it wasn't tuned on. The nearby-settings check wasn't run (it isn't run on a group of stocks), so this doesn't show whether the result depends on the exact settings. With the trades in a worse order, the worst fall was 35% or more in 1 of 20 reshuffles. 197 trades, enough to judge.
The rules: Enters when the 20-day exponential average crosses above the 50-day one; leaves when it crosses back below.
StratLab ran these rules through its own backtest on every stock in the group, after costs, and through four checks: unseen years, nearby settings, a bad-luck drawdown and enough trades. The page shows the return beside buy and hold and the result of each check. A verdict describes the past, not what comes next, and nothing here is investment advice.
