Falling prices for oil and other commodities pulled U.S. stocks modestly lower on Wednesday, nudging the Standard & Poor's 500 index slightly into the red for the year and putting it on course to snap a five-week winning streak.
Energy and mining companies led the decline, while consumer staples and utilities stocks bucked the broader downward trend.
Disappointing earnings from several companies, including Nike, also weighed on the market. Oil slumped 4%.
Trading was muted ahead of Friday, when markets will be closed for the Good Friday holiday.
“It's one of the lowest-volume days of the year,” said Erik Davidson, chief investment officer for Wells Fargo Private Bank. “We're seeing a little bit of a sell-off, but not much.”

A batch of company earnings also gave investors reasons to sell.
