Hedging: insurance paid for with return

Hedging means opening a position that profits in the scenario where the main position loses.

The classic example

An exporter knows they will receive foreign currency in six months and fixes the sale rate in advance. They give up a possible gain on a favourable move in exchange for certainty.

The key property

A hedge does not raise expected return — it lowers it. The price of less uncertainty is paid in return, and there is no other way.

Where private investors go wrong

Hedging direction rather than risk. Opening a short against your own portfolio "just in case" is not a hedge but a second bet requiring you to time it.

Hedging with the wrong instrument. Protecting an equity portfolio with an index future works only to the extent the portfolio resembles the index — Beta: how closely a security repeats the market.

Forgetting the cost of the hedge: it costs money continuously and helps rarely.

Simpler alternatives

Reduce the position. Raise the share of instruments that behave differently. Extend the horizon so interim swings stop mattering — The horizon: the one parameter you cannot change by deciding to.

For most private portfolios those three are cheaper and more reliable than any derivative.
