Basis risk

Risk that a hedge and the position being hedged develop differently.

In brief: Risk that a hedge and the position being hedged develop differently.

Meaning in practice

Basis risk remains when a future, ETF or derivative only approximates the underlying exposure. Hedging an individual share with an index may reduce market risk while leaving company-specific price moves in place.

Context for investors and traders

For investors, the term becomes practical in the context of objectives, time horizon, risk capacity and costs. A suitable solution can differ between two people even when they consider the same product or metric.

How to use this in practice

Use the term first to describe the situation and add verifiable data: time frame, benchmark, costs and liquidity. Only then does it become an assessment that can be connected to an investment objective and risk budget.

What to keep in mind
