Want to hedge your investment bets? It's complicated

Quite simply, portfolio hedging describes a variety of techniques that can be used to reduce risk exposure in an investment portfolio.

The purpose of portfolio hedging is to limit risk and curtail potential losses, according to certified financial planner Geri E. Pell. It's something that every investor should know about, because it can help ensure them against a negative event, says Pell, who is CEO of Pell Wealth Partners, a private wealth advisory practice of Ameriprise Financial Services.

This safety strategy also comes at a price, since hedging also limits potential profits, Pell explains. So, hedging, for the most part, is a technique not by which you will make money but by which you can reduce potential loss.

Since hedging has a cost, investors need to weigh such costs against potential benefits—on a case-by-case basis. For most buy-and-hold investors, hedging is unnecessary, since short-term price swings in a portfolio won't matter.
