Options trading is a popular way to participate in the stock markets without actually purchasing stocks. Instead you are purchasing a contract, which will allow you to purchase the stock at a specific price should you choose to. The main advantage that trading options has is that it requires a lot less money than dealing in the actual stock. The drawback is that it is more complicated.
