Everything this article says is true if you accept the postulate that people only trade stocks to make money. There are other reasons to trade individual stocks, however -- for instance, I often buy stock in companies that I want to support or just have an interest in. I vastly prefer getting a decent return from companies that I want to succeed to an equivalent return from index funds.
