Stocks ups and downs This is not the first time and won't be the last time that stocks are going up and then crash, but 3 senarios for investors.1- those who sell high and buy low and repeat make money.2- those including myself hold the stock for a long period of time and have a target price or time frame and dealing with these ups and downs, at the end may or may not make money.3- those who sell due to panic or margin call and lose money.
