In simple terms
To de-risk means reducing a measurable risk in a position or portfolio. Actions may include less size or leverage, lower concentration, more liquidity, or a consistent hedge.
It does not always mean closing everything. Cutting a position is one possible action; de-risking describes the purpose.
Before and after
A verifiable statement names the changed measure: gross or net exposure, planned maximum loss, concentration, liquidity, or factor sensitivity. Without a before-and-after measure, “I de-risked” remains ambiguous.
Limits
A tighter stop alone does not guarantee a smaller realized loss; execution, gaps, and liquidity matter. A hedge adds costs and its own risks. Rapid selling under stress can reduce exposure while worsening the fill. Evaluate the whole portfolio, not only the intention.
