Stocks have risen so often in the last five years that many investors may take further gains for granted even after the latest slump, according to Wells Frago’s Jim Paulsen. As Bloomberg reports, Paulsen’s ‘US stock market consistency indicator’ (which tracks the ratio of monthly gains and losses for the preceding five years), reached 3 for the first time since April 1999 – less than a year before the end of a bull market driven by Internet stocks – a level not seen since the late 1920s.
