A stock market crash is a rare experience, but the aftermath will last much longer than people count on it to. Stock market price ranges will move down dramatically, and the amount will escalate as the energy picks up. Stock market news channels will tell you that a crash is for one special rationale, but typically it is from a bunch that line up. The why for the long ongoing aftermath is due to the trouble that was brought on to the investor that was in during the stock market crash. Modern traders that either lived through or read about the stock market crash do not want to concern themselves to that form of risk.
A stock market crash is defined in different ways relying on who you ask. Most will say it is a big percentage fall on high volume that lasts a certain amount of time. The level of the drop in order to qualify as being a stock market crash is dubious, but usually it stands in the vicinity of at least 12%. Volatility will rise during a stock market crash, which can cause traders to get stopped out if they don’t have their risk variables thoroughly set up. Like any other time in the stock market, your risk should get your biggest focus at all times.
Volume level will rise on a stock market crash as market players are capitulating in order to keep their damages reasonable. A good indication to watch during the stock market crash is when volume ultimately makes one last spike and price quits going down. This is the indication of a sell climax, and could be the end of the down move. While this does not necessarily trigger a reversal of the stock market's path, it can still be useful in getting you positioned if that is what arises.
If you are trading the stock market, you have less risk during a stock market crash than if you were an investor, and holding on through the storm. You do give up the chance for a bigger move if you are not sticking around long, but most importantly, you give up the risk of being caught in a downdraft. Just because a stock market crash is rare, it doesn't mean that you should completely ignore the chances. When you do, it can very easily wind up harming, and not helping your stock trading.
