From Investorplace:
Contrary to popular belief, April isn’t a lethargic month for the market. Following on from what’s usually a bullish March, the S&P 500, on average, gains 1.2% for the month that just started. So it’s OK to hunt down stocks to buy without worrying about every pick being a dead end.
Perhaps this time around will be different. The index is typically up only 2.1% year-to-date at the end of March, but the S&P 500 is up about 5% this year so far. That sets the stage for some profit taking.
