Like spacecraft that pick up speed as they rise into the Earth’s stratosphere, growth stocks often seem to defy gravity. Let’s look at the trajectories of three of the hottest growth stocks of the 1990s: General Electric, Home Depot, and Sun Microsystems. (See Figure 7-1.) In every year from 1995 through 1999, each grew bigger and more profitable. Revenues doubled at Sun and more than doubled at Home Depot. According to Value Line, GE’s revenues grew 29%; its earnings rose 65%. At Home Depot and Sun, earnings per share roughly tripled. But something else was happening—and it wouldn’t have surprised Graham one bit. The faster these companies grew, the more expensive their stocks became. And when stocks grow faster than companies, investors always end up sorry. As Figure 7-2 shows: A great company is not a great investment if you pay too much for the stock. The more a stock has gone up, the more it seems likely to keep going up. But that instinctive belief is flatly contradicted by a fundamental law of financial physics: The bigger they get, the slower they grow. A $1-billion company can double its sales fairly easily; but where can a $50-billion company turn to find another $50 billion in business? Growth stocks are worth buying when their prices are reasonable, but when their price/earnings ratios go much above 25 or 30 the odds get ugly: Journalist Carol Loomis found that, from 1960 through 1999, only eight of the largest 150 companies on the Fortune 500 list managed to raise their earnings by an annual average of at least 15% for two decades.
