Millennials don't trust Wall Street -- and they're showing it by not investing in the stock market. Just 14 percent of respondents ages 18 to 29 say they trust Wall Street to 'do the right thing all or most of the time,' compared to 12% last year, according to a survey released this past week by Harvard University's Institute of Politics. This statistic has barely changed over the past five years. And 'millennials' distrust for Wall Street is illustrated in just how few are invested in stocks. Only 26% of millennials invest in equities, according to a March 2015 Bankrate survey, missing out on unprecedented returns. The S&P 500 is up 210% since its March 2009 low and strategists think the bull market still has fuel left. TheStreet's Scott Gamm reports from New York.
