The S&P 500 is up 8 points to 1880 shortly after the open. Yesterday, the index gained 15 points.
The key level to watch is the record 1883.97, which was set on March 21. The index was caught in a range trade in March but April is the most bullish month on the calendar for stocks. Even if economic data disappoints, you can make a case for buying stocks because it will keep the Fed on the sidelines for longer.
