I've experienced enough of that type of volatility. It doesn't rattle me anymore. I remember when I used to rush to log into my brokerage account while carnage was taking place. Part of me said I should be buying right now, not panicking. However, a persistent fear that a.) it's going to get much worse and b.) it might not get any better, keeps your from pulling the trigger and shakes you out of positions that will ultimately recover and then some. Powerful psychology works on most of us in those situations. It takes a ton of time to train your brain to work through it. I'm convinced you just have to see the same thing happen - repeatedly - before you make the smart decisions, not ones that your most intense emotions dictate. In this case, it means taking the next crash or correction in stride: Shake off the initial panic and buy those names you're convinced will lead not only the ensuing rally, but the inevitable bull run to come.
