Market watchers said there is more room for stocks to rise as investors use weakness in the market as an opportunity to add to positions.
"Until we see a clear change in momentum, pullbacks should still be viewed as long-term buying opportunities," said Randy Frederick, managing director of active trading and derivatives at the Schwab Center for Financial Research.
"With that said, a completely unexpected event could easily spark a pullback, especially at these lofty levels, so active traders intending to stay long should also consider maintaining downside hedges. I remain on high alert for a potentially larger correction in May or early June."
