Patience pays
Most advisors who aren't making a commission on your trades will say "buy regularly, diversify your portfolio, and hold." Trying to time the market or pick the next winner is fun, but risky, especially when you're sure you know which way it's going to go.
They also recommend that you own mostly equities when young, shifting the ratio slowly to mostly fixed-income securities by retirement age. I think the goal of investing should be protection of your capital, with modest real (inflation-adjusted) growth.
