They have seized upon a fairly bad situation: a stunning number of defaults and foreclosures in the subprime arena, although just a small part of the total financial picture of the United States. They have then tried — with the collaboration of their advance guards in the press — to make it seem like a total catastrophe so they could make money on their short sales. They sense an opportunity to trick other traders and poor retail slobs like you and me, and they generate data and rumor to support their positions, and to make money. More than that, they trade to support the way they want the market to go. If they are huge traders like some of the major hedge funds, they can sell massively and move the market downward, then suck in other traders who go short, and create a vacuum of fear that sucks down whatever they are selling.

Analysts say that at the start of trading, the stock markets fell because a lot of investors were cashing in, but later in the day, the reason the stock markets kept on falling was because traders began to have reservations about the impact of an Obama administration on the business sector.

It's important to remember that this doesn't mean the stock market returns exactly 10% a year, every year. It's actually unusual for the market to return exactly 10% in a given year. The S&P 500 has only posted a return of between 10.0% and 10.9% four times since 1926 and only returned exactly 10% once, in 1966, according to S&P data that includes dividends.

Stock returns are wild and unpredictable. Since 1927, the S&P 500 stock index has gained 10.4% a year on average. But in any given year it could be up 29.9% or down 9.0% or somewhere in between, says IFA.com.

To do that, it's important to understand the power of diversification and the benefits of owning many types of stocks, from large value-priced stocks to small value-priced stocks. Diversification lets you minimize the risk posed by a single stock or type of stock and lets you still get your share of the market's return.
