The one-year anniversary of the S&P 500’s all-time high took place on May 21, 2016. Stocks have largely been spinning their wheels for the past year. The S&P 500 has failed to return to its May 21, 2015, record high for 12 months. Stocks have actually been spinning their wheels for even longer, considering the S&P 500 is at the same level as it was on November 18, 2014 — an 18-month stretch. This week we take a look at what the stock market’s lackluster performance since the last record high might mean for the current bull market, now the second longest since 1950.
