If a business is worth a dollar and I can buy it for 40 cents, something good may happen to me.
--Warren Buffett
The best Dow stocks of the past 10 years don't include Microsoft or Intel. But Caterpillar (Cat) makes the cut with a 212% return. In 1997, in the midst of tech madness, the market was so bored by the company's industrial-machinery business that investors paid just $11.50 for each dollar of earnings. If the stock's current value of 16.1 times earnings is right, that's nearly a 30% discount. Smart investors didn't need to foresee the coming construction boom. They only needed to call a bargain a bargain and trust the market to eventually wise up.
