Hedge

A hedge is a position taken in the opposite direction so that a loss on one side is offset by a gain on the other. The point is not to earn more but to shrink how much an unexpected move can shake you.

Real examples make it clear. Airlines face soaring costs when oil rises, so they lock in contracts to buy fuel at a set price. If oil climbs, those contracts gain and offset the higher fuel bill. A Korean investor buying US stocks through a currency-hedged product is doing the same thing, guarding against losses if the won strengthens.

The key point is that hedging is never free. Either you pay a cost like an insurance premium, or you give up the gain you would have had if things moved in your favor. The airline that hedged missed out on cheap fuel when oil fell. A hedge is best understood as a trade that gives up some upside to rule out the worst case.

For individual investors, the most practical hedge is not derivatives but diversification. Spreading across stocks and bonds, countries and currencies already prevents one collapse from taking everything with it. Tools like inverse ETFs and options require getting direction right and decay with holding costs over time, so for the unpracticed they tend to become a new risk rather than a hedge.
