就是用一种确定的方式来减少LOSS。当然代价是减少RETURN。

if A occurs, B must occur. Then do somethign on B to mitigate the impact from A. for example, if stock A drops sharply, its PUT must go up. you can buy some PUT to reduce possible loss in stock price drop. It oil goes up, COP stock must go up. you can buy some cop stocks to hedge your costs for oils. If inflation is crazy, gold must go up. you can buy some gold to hedge possible impact from inflation. Usually small investors do not need to worry about hedge. The best hedge is to sell the security and do nothing.
