April poised for continued stock market gains, say experts.

The ongoing stock market rally that began in mid-October is likely to extend into April as many investors are caught off guard by the bullish momentum. According to Goldman Sachs, positioning data shows that hedge funds and retail investors are overly bearish, essentially fighting the ongoing rally. The bank's Scott Rubner isn't surprised by stocks rallying in the face of negative news. If momentum continues to flip to the upside, trend-following traders on Wall Street could be forced to exit their short positions and flip their exposure to long equities, essentially adding fuel to the ongoing rally.
