In stage four, once again they’re crowded around me — but this time it’s to tell me what stocks I should buy. Even the dentist has three or four tips… - Peter Lynch

If my favorite Internet company sells for $30 a share, and yours sells for $10, then people who focus on price would say that mine is the superior company. This is a dangerous delusion. What Mr. Market pays for a stock today or next week doesn’t tell you which company has the best chance to succeed two to three years down the information superhighway.

If the p/e of Coca-Cola is 15, you’d expect the company to be growing at about 15 percent a year, etc. But if the p/e ratio is less than the growth rate, you may have found yourself a bargain. A company, say, with a growth rate of 12 percent a year (also known as a “12-percent grower”) and a p/e ratio of 6 is a very attractive prospect.

The best way to handle a situation in which you love the company but not the current price is to make a small commitment and then increase it in the next sell-off.
