Like poker, investing is a zero-sum game: there are only so many chips on the table. When two people trade a stock, one must win and one must lose. If the stock goes up after you buy it, you win. But you’ve got to win by a big enough margin to cover those transaction costs. Wait, it gets worse! If your stock goes up, you’ll also have to pay taxes on your profits when you sell the stock. For investors in an actively managed fund, this combination of hefty transaction costs and taxes is a silent killer, quietly eating away at the fund’s returns!
