(CNBC) — U.S. stocks closed mostly lower on Wednesday as investors digested remarks from Fed Chair Janet Yellen, as well another choppy trading in oil.
"It's a lack of bullish impetus," said Adam Sarhan, CEO of Sarhan Capital. "Anytime you see the market trying to rally, you get strong selling pressure."
Leading the three major indexes was the Nasdaq composite, which briefly rose over 2 percent as technology stocks gained ground. Netflix and Alphabet shares gained 2.7 percent and 0.8 percent, respectively.
