US STOCKS FALL WITH CHIPS; HEALTHCARE POSTS A RECORD HIGH

U.S. stocks ended lower on Tuesday, led by a more than 1% drop in the Nasdaq .IXIC and sharp declines in chip stocks.

Still, healthcare shares rose, and the S&P 500 Healthcare index .SPXHC and Nasdaq Biotech .NBI registered record closing highs. Energy .SPNY also gained.

Weakness in the chip stocks followed a drop in Samsung Electronics' 005930.KS shares in South Korea despite the company reporting a jump in quarterly operating profit.

Some investors are worried about how well tech shares and the AI-driven rally may hold up as S&P 500 companies get set to report results for the second quarter. Earnings season unofficially begins next week.

The S&P 500 technology sector .SPLRCT ended 1.6% lower, while an index of semiconductors .SOX fell 4.6%.

Also falling were shares of SpaceX SPCX.O, which ended down 6.8%. SpaceX's addition to the Nasdaq-100 index on Tuesday was expected to unleash billions in passive buying. The stock joins the index less than a month after the company's market debut on June 12.

In other tech-related news, Reuters reported that Chinese startup DeepSeek is developing its own AI chip, a move that could reduce its dependence on Nvidia NVDA.O and Huawei chips.

Nvidia shares ended 0.7% higher.
