Tech and AI Surge Propel S&P 500 and Nasdaq to Record Highs Amid Global Equity Rally

Bullish (0.8)Impact: High

Published on May 15, 2026 (2 hours ago) · By Vibe Trader

Global equities experienced a significant rally, driven by strong performances in technology and AI-related stocks, according to Deutsche Bank analysts. The S&P 500 rose by 0.77%, surpassing the 7,500 mark for the first time and reaching a new record high, while the Nasdaq also achieved a record with a gain of 0.88% [1]. This positive momentum was attributed to encouraging signals from the Trump-Xi summit in Beijing, robust US economic data, and easing concerns about inflation, which collectively boosted risk appetite among investors [1].

Within the S&P 500, Cisco emerged as the top performer, surging 13.41% after releasing a better-than-expected outlook [1]. The broader optimism around AI was further underscored by a 68% opening jump for AI chipmaker Cerebras Systems following its $5.5 billion IPO [1]. Nvidia led gains among the so-called 'Magnificent 7' stocks, rising 4.39%, while the group as a whole advanced by 0.49% [1]. US investment-grade credit spreads also tightened to their lowest level in three months, reflecting improved market sentiment [1].

The rally was not limited to US markets. European equities advanced, with the STOXX 600 up 0.76% and Italy’s FTSE MIB climbing 1.15% to reach a post-2000 high [1]. In Asia, performance was mixed: while the Nikkei (-1.16%), KOSPI (-3.66%), and Hang Seng (-0.95%) declined, mainland Chinese equities outperformed their regional peers, with the CSI 300 and Shanghai Composite posting modest gains of 0.04% and 0.12%, respectively [1].

Deutsche Bank analysts highlighted that risk assets were further buoyed by various positive corporate headlines and the ongoing enthusiasm for AI-related investments [1].

CONCLUSION

The rally in technology and AI stocks has driven US and European equity indices to new highs, supported by positive macroeconomic signals and strong corporate performance. Market sentiment remains optimistic, with tightening credit spreads and robust IPO activity in the AI sector reinforcing risk appetite.
