Beware reckless link posting

A lot of that could be caused by automatic trailing sales triggers. After you've owned a stock for awhile and it has increased in value it is prudent to put a "stop-loss trigger" or a "trailing" sales trigger on it. If for some reason the stock drops to a certain pre-set lower price than it is currently trading then it will automatically be sold. Mostly, that is to keep you from waking up one day and finding one of your stocks has gone bankrupt, but it also gets triggered in a case like this.
