Das Risiko ist hier sicher nicht zu unterschätzen. Betreffend Aktien mit schlechter historischer Performance fand ich dieses interessante Statement, dass auf Vange zutreffen dürfte:
"What should I do if the stock price has been declining for a long period for no apparent reason? ... Most professional investors view a slow, steady decline in a stock's price as an excellent buying opportunity. Their reasoning is that if there were real problems with the company, the rush of investors to sell would force the price down sharply in a short amount of time. Instead, they theorize that declines in price are caused by money managers selling their stake in a company to raise money and this, in turn, causes some investors to follow suit."
