The best way to understand hedging is to think of it as insurance. When people decide to hedge, they are insuring themselves against a negative event. This doesn't prevent a negative event from happening, but if it does happen and you're properly hedged, the impact of the event is reduced. So, hedging occurs almost everywhere, and we see it everyday. For example, if you buy house insurance, you are hedging yourself against fires, break-ins or other unforeseen disasters.

Portfolio managers, individual investors and corporations use hedging techniques to reduce their exposure to various risks. In financial markets, however, hedging becomes more complicated than simply paying an insurance company a fee every year. Hedging against investment risk means strategically using instruments in the market to offset the risk of any adverse price movements. In other words, investors hedge one investment by making another. Technically, to hedge you would invest in two securities with negative correlations. Of course, nothing in this world is free, so you still have to pay for this type of insurance in one form or another.

Although some of us may fantasize about a world where profit potentials are limitless but also risk free, hedging can't help us escape the hard reality of the risk-return tradeoff. A reduction in risk will always mean a reduction in potential profits. So, hedging, for the most part, is a technique not by which you will make money but by which you can reduce potential loss. If the investment you are hedging against makes money, you will have typically reduced the profit that you could have made, and if the investment loses money, your hedge, if successful, will reduce that loss.

Even if you never hedge for your own portfolio you should understand how it works because many big companies and investment funds will hedge in some form. Oil companies, for example, might hedge against the price of oil while an international mutual fund might hedge against fluctuations in foreign exchange rates. An understanding of hedging will help you to comprehend and analyze these investments.

Conclusion

Risk is an essential yet precarious element of investing. Regardless of what kind of investor one aims to be, having a basic knowledge of hedging strategies will lead to better awareness of how investors and companies work to protect themselves. Whether or not you decide to start practicing the intricate uses of derivatives, learning about how hedging works will help advance your understanding of the market, which will always help you be a better investor.
