So smile when you read a headline that says "Investors lose as market falls." Edit it in your mind to "Disinvestors lose as market falls-but investors gain." Though writers often forget this truism, there is a buyer for every seller and what hurts one necessarily helps the other. (As they say in golf matches: "Every putt makes someone happy.")
Most investors, both institutional and individual, will find that the best way to own common stocks (shares') is through an index fund that charges minimal fees. Those following this path are sure to beat the net results (after fees and expenses) of the great majority of investment professionals.
Investing is the greatest business in the world because you never have to swing. You stand at the plate; the pitcher throws you General Motors at 47! U.S. Steel at 39! And nobody calls a strike on you. There's no penalty except opportunity. All day you wait for the pitch you like; then, when the fielders are asleep, you step up and hit it.
