Zweig, Light and Pleven reflect on the experience of the last 5 years in the stock market. Investors who went through severe anxiety for higher investment allocation in stocks in 2009 now feel the opposite for low investment allocation in stocks. What does one make of this, and what have we learned, is the question posed. One lesson is that investors should be wary of relying too much on predictions. At one point predictions of Goldman Sachs and other bank economists was for the S&P at 1250 at the end of 2012, when it was 1421 in April 2012. The eurozone crisis and the sluggish U.S. job growth, debt overhang, were major factors in their assessment. The eurozone recovered faster than expected and the Iranian nuclear crisis risks were reduced through negotiations. QE 1, QE 2, QE 3 by the U.S. Fed under Bernanke provided support to the market. Banks recovered faster than expected with help from the Fed. Another lesson is that this can happen with higher volatility, 900 point drops occured in May 2010 and there were drops in April 2012 and other dates. Zweig gives April 2011 as a date for the start of a 5 month bear market, citing Oct 4, 2011 as another date with the market dropping 21% from the April 2011 peak. Another lesson is that performance statistics can play tricks, a month or a year can make a big difference. If 2013 is not included the statistics look very different, if 5 years go back to Feb 2009 when there was a 11% decline instead of March 2009 when there was a 9% improvement the numbers change quite a bit. Another lesson is that macroeconomic news played a major part in the story of the stock market in 2009-2014 and continues today, with continuing support and vigilance from the U.S. Fed and the ECB. The bad news from the eurozone throughout 2011 and into 2012, and sluggish job markets in the U.S., took a positive turn in 2013. The U.S economy is improving and the eurozone is returning to growth gradually in 2014. Because of different timing in their recovery P/E ratios are higher in the U.S., than in Europe....
