Buy Low, Sell High (of course...) You hear the mantra to buy low, and sell high. Did you know that most investors do the exact opposite? Investors see that their investment is going up and they think, "Yeah! This investment is going great! Me wants more!" And that is right before the investment takes a nosedive. And with a nose-diving investment, the inclination is not to think, "Yeah, I want to put my money in that plummeting investment!" You think the opposite: "I gotta get out!" So right at the bottom, you sell your investment, having eaten all of the losses.
Even when the market may be crashing. Hold on tight since often times once ppl start selling, things go back up.
