The increase is attributed to dip-buying after Monday's decline, despite cautious sentiment due to proposed global tariffs and U.S.–Iran tensions. Strength in chip stocks, particularly Advanced Micro Devices (AMD), which surged 11% after a deal with Meta Platforms (META), also supported market sentiment.

The Vanguard S&P 500 ETF (VOO), which tracks the S&P 500 Index (SPX), edged up about 0.06% in pre-market trading on Tuesday after a sharp AI-driven sell-off in the major averages a day earlier. The modest rebound appeared to reflect dip-buying following Monday's drop, though sentiment remained cautious due to President Donald Trump's proposed 15% global tariffs and ongoing U.S.–Iran tensions. ### Claim 50% Off TipRanks Premium - Unlock hedge fund-level data and powerful investing tools for smarter, sharper decisions - Stay ahead of the market with the latest news and analysis and maximize your portfolio's potential Strength in chip stocks also helped support market sentiment, with Advanced Micro Devices (AMD) jumping about 11% in early trading on Tuesday after Meta Platforms (META) announced a multi-year AI data-center deal, which likely provided a small lift to the broader market. During Monday's regular trading, the three U.S. indexes closed lower amid fears of AI-led disruption. Software names such as Microsoft (MSFT) and CrowdStrike (CRWD) were among the notable losers, along with several cybersecurity and financial stocks. The DJIA dropped 1.7%, led by IBM's (IBM) plunge, and the Nasdaq Composite fell 1.1%, while the S&P 500 declined 1%, turning negative for the year. Overall, VOO has gained 0.05% over the past five days but has gained 15% over the past year. ### 相关股票 - [AMD (AMD.US)](https://longbridge.com/zh-CN/quote/AMD.US.md) - [iShares Core S&P 500 (IVV.US)](https://longbridge.com/zh-CN/quote/IVV.US.md) - [SPDR S&P 500 (SPY.US)](https://longbridge.com/zh-CN/quote/SPY.US.md) - [GraniteShares 2x Long AMD Daily ETF (AMDL.US)](https://longbridge.com/zh-CN/quote/AMDL.US.md) - [Invesco S&P 500 Equal Weight Tech ETF (RSPT.US)](https://longbridge.com/zh-CN/quote/RSPT.US.md) - [Meta Platforms (META.US)](https://longbridge.com/zh-CN/quote/META.US.md) - [S&P 500 (.SPX.US)](https://longbridge.com/zh-CN/quote/.SPX.US.md) - [VG S&P 500 (VOO.US)](https://longbridge.com/zh-CN/quote/VOO.US.md) - [Direxion Daily AMD Bull 2X Shares (AMUU.US)](https://longbridge.com/zh-CN/quote/AMUU.US.md) ## 相关资讯与研究 - [Instagram tests a feature to let you see your ex's Stories without a trace — and it's going to cost you](https://longbridge.com/zh-CN/news/281134560.md) - [Tech Wrap March 30: OPPO Find X9 Ultra, WhatsApp on CarPlay, Blaupunkt](https://longbridge.com/zh-CN/news/281041030.md) - [Draft IT regulations may widen govt oversight on social media content](https://longbridge.com/zh-CN/news/281133616.md) - [Govt proposes to bring independent news creators under MIB purview](https://longbridge.com/zh-CN/news/281049326.md) - [Meta Superintelligence Labs is quietly building a hardware team](https://longbridge.com/zh-CN/news/281657591.md)
