"I'm tellin' ya, if I buy, I'll tank it." Actually that usually happens when people trade stocks. Stocks bought tend to underperform. Stocks sold tend to do well. Many studies over many years show that people get trading backwards... which is one reason I almost never trade my blue chips except where there's a significant tax advantage to be had.

That's also a reason index funds do well. They don't trade often.
