The complexity and variety of financial instruments described earlier has given rise to a great many strategies. A buyer of a stock might also write a call option. If the stock’s value rises above the exercise price of the call option, he can exercise it and claim a profit. If the stock’s value falls, some of the loss is covered by money received as a premium (the sale price) for writing the call. A major subset of investment strategies do this, attempt to reduce risk by compensating for it with other investments and this practice is called hedging. Buying shares of Shoe Company A certain that Company A is well-managed and will make the best of the situation in its market, but then covering for the whole country perhaps wearing sandals instead by shorting Shoe Companies B and C to do so, is an example. As a matter of fact, with enough option plays, profiting from almost any predicted trend is possible.
