"Sell In May" ... And June

"Sell in May and go away" -- the old equity-market adage still holds water, but, as Bloomberg's Mark Cudmore explains, it's important to note how the seasonals have evolved since the great financial crisis.
In its original usage, the motto implied it’s advisable to cash out of equities at the end of May and enjoy a long summer of relaxation before returning to invest again. It wasn’t just a flippant saying; the facts tallied with the intuition.
