Stocks can be divided into two categories: those for trading and those for investing. Within trading stocks, you make money by figuring out whether other traders will keep buying or start selling the stock and positioning yourself accordingly for a few weeks or even days. By contrast, with investing stocks you aim to buy into a company at an attractive price, given the worth of its assets and likely future profits, regardless of when the value will be recognized by the market. This way, you can steer clear of overpaying for fashionable dogs.
    There’s nothing revolutionary about this strategy, of course. It’s just a question of calmly mixing and matching some old, and apparently somewhat contradictory, stock market wisdom and applying it to a hot market. About 70 years ago, British economist John Maynard Keynes said investors should view the market as a beauty contest, and they should mainly buy, trading stocks that other people would find attractive. Benjamin Graham, the father of modem securities analysis, bristled at that idea. He lamented that stock buyers, though almost always called investors, are often actually speculators. Instead, he preached that they should make a hardnosed assessment of the inherent value of companies and search out investing stocks.
