Growth rates for many large companies can still be very satisfactory and future earnings can be more predictable than in smaller corporations. Since there is a larger capitalization, those large companies are more apt to attract institutional buyers. And remember that supply and demand ultimately determines a stock price. Here is where you normally find the rapid growth rates. One problem you face is in deciding whether the fast growth can be sustained.
Many factors can enter into a slowdown or elimination of growth.
First, an investor should try to determine if the past record was management or product growth. That's not always easy to do. Not too many years ago, investors went overboard in buying the stocks of any company, which made word processors. Most of the stocks skyrocketed, but the fall was just as dramatic. Word processors are still being purchased for offices, but the buyers are selective.
