As we move into April, it's important to look at the stock market's long history of making most of its gains each year in a favorable 'season' of November to April, while most of its corrections and bear market down-legs take place in an unfavorable season from May to October.
Additionally, the historical evidence that clearly shows seasonal investing substantially outperforms the market over the long term (while taking only 50% of market risk) includes those individual years when it did not outperform.
The big question for this year is whether it will be three straight years that seasonality does not 'work'. Or will it more likely resemble 2011 (or worse), when massive QE stimulus did not prevent a 20% market plunge in the unfavorable season. (The only thing that prevented it from becoming worse in 2011 was that the Bernanke Fed rushed in to double the QE from $40 billion a month to $85 billion a month).
