Investor March Madness: We’re wired for blunders, but can improve odds

Time now to observe two of the most solemn anniversaries in the investor's calendar. March 9 marks five years since the Dow plunged to its lowest point of the past 17 years, in the dismal pit of the financial crisis. March 10 is 14 years since Nasdaq levitated to its all-time high in the sparkling delirium of the Internet bubble. It seems March Madness happens on Wall Street too.
