The implication is that you cannot systematically outperform the market, unless you have information other people don't or can access part of the market others can't. But that doesn't mean you can't make money. Over time you can expect, but are not guaranteed, that riskier assets generate higher returns. Stocks, on average, return more than bonds because they are riskier. The stock of smaller companies is riskier than larger ones, so they typically generate more returns. It's a straightforward concept, but often poorly understood. Even many sophisticated investors get it wrong.
