UBS•UBS maintained buy ratings on Microsoft, Amazon and Oracle after their combined 1Q26 revenue surged 39% to $84.8 billion and forecast $8.5 billion sequential growth in 2Q26. The bank warned of elevated U.S. tech concentration risk after the S&P 500’s record run and advised reallocating into Japan, China and high-quality bonds.
1. Hyperscaler Ratings and Performance
UBS maintained buy ratings on Microsoft, Amazon and Oracle after their combined 1Q26 revenue reached $84.8 billion, up 39% year-over-year, driven by AI computing demand. The group posted $6.5 billion in sequential revenue additions, marking four straight quarters of elevated gains.
2. 2Q26 Revenue Forecast
The bank forecasts $8.5 billion in sequential revenue additions for the hyperscaler group in 2Q26, against Wall Street estimates of $8.1 billion to $9.8 billion through year-end. Google Cloud led quarterly growth at 63%, while AWS and Azure delivered 28% and 39%, respectively.
3. Tech Concentration Risk and Rebalancing Advice
UBS cautioned that the S&P 500’s record high has concentrated returns in a few large technology firms, increasing exposure risk. It urged clients to diversify into Japan, China, emerging markets, Swiss equities, consumer discretionary and high-quality government bonds with short-to-medium maturities.
