The stock market is always volatile. There are risks involved in investing your money in a company's stock. Savvy investors take the time to research the company thoroughly before investing in its stock. But one risk investors often overlook is market risk, or the volatility of one market and how it might affect another. This was seen in February 2007, in a dramatic turn when the Chinese stock market dropped a whopping 9% in a single day, causing a tidal wave effect throughout the world. The United States Dow Jones Industrial Average fell by 4.3% in the Chinese aftermath, its worst decline since the terrorist attacks of 2001.
