When stocks are attractive, you buy them. Sure, they can go lower. I've bought stocks at $12 that went to $2, but then they later went to $30. You just don't know when you can catch the bottom.

Investors should focus on what they can control: costs, diversification, and time horizon.

A real decision is measured by the fact that you’ve taken a new action. If there’s no action, you haven’t truly decided.
