Until You Learn This Investing Lesson, You Don't Know Anything
Even if you've only been an investor for a few days, you certainly know this much already: There's never a shortage of advice regarding stocks. Whether it's buying, selling, or holding, the financial experts always have an opinion for you.
They can be a bit pushy with those opinions, too, suggesting you act immediately on their advice. It would be easy to conclude you're supposed to trade frequently if you want to have any shot at outperforming the market.
Nothing could be further from the truth, however. Leaving your portfolio alone for months at a time, or even years, is the real secret to success. That's because you're never going to guess the market's next major move. Your best bet is standing pat, trusting that quality stocks will ultimately reflect broad economic growth.
