The S&P 500 and Nasdaq Composite both surged to all-time record highs on May 8-9, 2026, capping a remarkable six-week winning streak for both major indices. The S&P 500 climbed 0.84 percent to close at 7,398.93, while the Nasdaq jumped 1.71 percent to finish at 26,247.08, both marking fresh historic peaks that underscored the strength of the current bull market.
Alphabet, the parent company of Google, emerged as the standout performer among the Magnificent Seven stocks, surging approximately 10 percent in a single session. The rally made Alphabet the best-performing member of the elite Big Tech group, pushing its year-to-date gains to an impressive 23 percent. Investors rewarded the company for its strong Google Cloud division results, which posted revenue growth of 63 percent, signaling robust demand for artificial intelligence infrastructure.
In contrast, the social media giant formerly known as Facebook saw its shares tumble approximately 8 percent despite reporting strong quarterly results. Investors expressed concern over the company's rising capital expenditure plans, which signaled increasingly aggressive spending on AI infrastructure. The divergent reactions to these two tech giants highlighted how markets are now differentiating between companies based on the efficiency and returns of their AI investments.
The broader market rally was supported by a strong April jobs report, which provided evidence that the labor market remains resilient despite economic uncertainties. For the week, the Nasdaq climbed an impressive 4.5 percent while the S&P 500 gained 2.3 percent, reflecting broad-based investor optimism. The six consecutive weeks of gains for both indices represented the longest winning streak in several quarters.
Big Tech earnings season revealed a clear theme across the sector: companies demonstrating tangible returns from their artificial intelligence spending are being handsomely rewarded by investors, while those perceived as spending without clear near-term payoffs face selling pressure. This dynamic has reshaped how Wall Street evaluates technology companies, placing greater emphasis on AI monetization metrics rather than simple revenue growth.
Market analysts noted that the combination of strong corporate earnings, particularly from the technology sector, alongside positive macroeconomic data, created ideal conditions for the record-setting rally. The breadth of the advance suggested that the bull market has expanded beyond a narrow group of stocks, with multiple sectors participating in the gains.
Looking ahead, investors will continue to monitor whether the remaining Big Tech companies can deliver earnings that justify their elevated valuations. The market appears to be entering a phase where AI spending must translate into measurable revenue growth, setting the stage for potential continued divergence between winners and laggards in the technology sector.
