Stop-Loss Strategies improves outcomes when you use clear allocation rules, position limits, and periodic rebalancing instead of one-off decisions.
Stop-Loss Strategies means using a clear process so no single position, sector, or market move can disproportionately impact your portfolio.
Use stop-loss levels to predefine maximum downside per position. Place stops where your thesis is invalidated, not at random percentages, and adjust for volatility to avoid repeated whipsaws.
For the full framework, see Stop-Loss Strategies.

It is generally beneficial when used with clear risk limits, but over-applying any single approach can reduce flexibility and expected returns.
It is most useful when combined with complementary concepts from the same cluster and explicit risk controls.
