The benchmark S&P 500 closed higher in choppy trading on Wednesday, as investors weighed an uptick in Treasury yields amid positive corporate results particularly from technology giants.

An auction of a record US$70 billion worth of five-year US Treasury notes on Wednesday helped to push bond yields higher and had weighed on equities. The benchmark 10-year Treasury note rose five basis points to 4.6459 percent.

The Dow finished lower while the Nasdaq ended higher.

Investors were also focused on quarterly earnings from companies, especially from megacap growth stocks. Shares of Meta Platforms fell 11 percent in extended hours trading after the tech giant reported that its capital expenditure could reach up to US$40 billion in 2024, even as its first quarter revenue beat estimates.

Microsoft and Alphabet are scheduled to report their results later this week.

Tesla jumped 12 percent after the electric vehicle maker's plans to boost production and roll out more affordable models overshadowed its weak quarterly results.

"My biggest concern is the bond market, particularly the long end of the US yield curve," said Bill Strazzullo, chief market strategist at Bell Curve Trading in Boston.

The S&P 500 gained 0.02 percent to 5,072 and the Nasdaq Composite gained 0.10 percent, to 15,713. The Dow Jones Industrial Average fell 0.11 percent, to 38,461.
