They sell at the end of uptrends, when they can dispose of large blocks of shares without driving the price down against themselves. So we have no way to know whether we have dumb money selling a stock that will soon go to $10 or more, or whether we have smart money getting out while the getting is good, just before the stock bounces down from the top of its trading channel.
