By Chantico Advisors I groan when I hear so-called investing pundits discuss how to think about the profits from winning trades, or "house money" to borrow a gambling term. Some behavioral finance experts have studied how investors tend to take greater risks and make mistakes with house money. That's one reason I get annoyed when "experts" recommend that when a stock enjoys strong gains, the investor should take the originally invested money off the table — but let the house money (profits) ride. That way, you can't lose, right? Wrong!
