Date Published
1. The Fatal Flaws of Static Stop Losses
Why Arbitrary 2% or 5% Stops Destroy Strategy Expectancy
Setting an arbitrary 2% stop loss on Tesla (which has a 4.5% daily ATR) guarantees that ordinary market noise will stop you out. Conversely, setting a 2% stop on Johnson & Johnson takes on excessive risk relative to its daily movement.
Volatility-adjusted stops scale stop distances dynamically based on prevailing market conditions.
