March Madness is officially upon us as the 2015 NCAA Basketball Tournament started yesterday evening in Dayton, OH. With more than an estimated 40 million Americans filling out more than 70 million brackets, which resulted in more brackets than ballots cast for either President Obama or Mitt Romney in the 2012 election, most of America’s eyes will be focused on their standings within their respective office pools rather than on their portfolios. According to market data provided by Kensho, over the past 10 years between March 17 and April 6, every single stock in the Dow Jones average has had a positive return. Broadening our scope to include the S&P 500 and only those companies that were around for the past 10 years, Kensho also found that only 12 of the 445 stocks included in the analysis experienced a negative average return. Provided with this information, where will you spend more time focusing – on your brackets or on the markets?
