Biggest stock movers today: Chinese stocks, and more

Stock futures edged up in premarket trading on Tuesday, despite rising concerns over the Middle East, as investors braced for an eventful week.

Here are some of Tuesday’s biggest stock movers:

Biggest stock gainers

• Super Micro Computer (NASDAQ:SMCI) shares rose over 4% Tuesday morning, following a nearly 16% surge the previous day after the successful deployment of over 100,000 GPUs with its innovative liquid cooling solution system for leading AI factories and cloud service providers. These solutions, which can significantly lower power consumption by up to 40%, offer substantial benefits such as reduced costs and improved performance in data centers. Super Micro’s ability to provide a comprehensive package, including cold plates, a specialized CDM, and a state-of-the-art CDU, streamlines deployment and online operations. This comprehensive approach has made Super Micro a preferred choice for data center operators seeking efficient, cost-effective solutions to meet their technical and financial objectives.
• DocuSign Inc. (NASDAQ:DOCU) shares jumped over 6% following news that S&P Dow Jones Indices will add the stock to the S&P MidCap 400 before the market opens on Friday, October 11. DocuSign will replace MDU Resources Group Inc. (MDU) in the S&P MidCap 400, while MDU Resources will move to the S&P SmallCap 600, replacing Chuy’s Holdings Inc. (CHUY).

Biggest stock losers

• China’s National Development and Reform Commission’s failure to announce significant new stimulus measures at a press briefing on Tuesday sent ripples through the Chinese stock market in the United States. As a result, shares of prominent Chinese companies such as Weibo (NASDAQ:WB), NIO (NYSE:NIO), Niu (NASDAQ:NIU), Futu Holdings (NASDAQ:FUTU), Bilibili (NASDAQ:BILI), Ke Holdings (NYSE:BEKE), and Kingsoft Cloud (NASDAQ:KC) experienced double-digit declines, with some dropping more than 15%.
