美股牛市继续？估值高企面临业绩考验

Group 1 - The U.S. stock market is extending its strong spring performance into summer, with the S&P 500 index reaching a historical high of 6201 points, driven by expectations of Federal Reserve rate cuts, reduced tariff risks, and potential tax and fiscal stimulus plans from Congress [1] - Concerns are rising about whether corporate earnings can support the recent market gains, as the S&P 500 is currently trading at a high valuation with a price-to-earnings ratio of 22.8, which is considered expensive historically [1][2] - Nearly half of the 11 major sectors in the S&P 500 are expected to see flat or declining earnings, with significant growth concentrated in the communication services and information technology sectors [2] Group 2 - The total earnings for S&P 500 constituents in Q2 are projected to grow by 5.9% year-over-year, reaching approximately $529 billion, while the index itself has risen about 10% since the end of March, outpacing earnings growth [2] - The equity risk premium, which measures the compensation investors require for taking on risk, is currently at 2.4 percentage points, the lowest level since the early 2000s, indicating limited demand for risk compensation despite high valuations [3] - Market volatility is near its yearly low, with the Cboe VIX index at 16.62, suggesting traders expect lower daily fluctuations in the S&P 500 compared to earlier in the year [3]
