Historically, investing in stocks has generated a return, over time, of between 11 and 15 percent annually depending how aggressive you are. Stocks outperform other investments since they incur more risk. Stock investors are at the bottom of the corporate "food chain." First, companies have to pay their employees and suppliers. Then they pay their bondholders. After this come the preferred shareholders. Companies have an obligation to pay all these stakeholders first, and if there is money leftover it is paid to the stockholders through dividends or retained earnings. Sometimes there is a lot of money left over for stockholders, and in other cases there isn't. Thus, investing in stocks is risky because investors never know exactly what they are going to receive for their investment.

What are the attractions of blue chip stocks?

1. Great long-term rates of return.

2. Unlike mutual funds, another relatively safe, long term investment category, there are no ongoing fees.

3. You become a owner of a company.

So much for the benefits - what about the risks?

1. Some investors can't tolerate both the risk associated with investing in the stock market and the risk associated with investing in one company. Not all blue chips are created equal.

2. If you don't have the time and skill to identify a good quality company at a fair price don't invest directly. Rather, you should consider a good mutual fund.

Selecting a blue chip company is only part of the battle - determining the appropriate price is the other. Theoretically, the value of a stock is the present value of all future cash flows discounted at the appropriate discount rate. However, like most theoretical answers, this doesn't fully explain reality. In reality supply and demand for a stock sets the stock's daily price, and demand for a stock will increase or decrease depending of the outlook for a company. Thus, stock prices are driven by investor expectations for a company, the more favorable the expectations the better the stock price. In short, the stock market is a voting machine and much of the time it is voting based on investors' fear or greed, not on their rational assessments of value. Stock prices can swing widely in the short-term but they eventually converge to their intrinsic value over the long-term.

Investors should look at good companies with great expectations that are not yet imbedded in the price of a stock.
