标普 500 指数

核心美国价值 ETF - iShares

<p>Polymarket 交易者预测，2026 年 5 月 15 日标普 500 指数将低开，此前该指数创下 7,500 以上的历史收盘纪录。尽管上涨了 0.77% 至 7,501.24，但对估值过高和市场集中度的担忧依然存在。强劲的企业盈利，尤其是思科系统的表现，支撑了股票市场，但策略师警告称，市场对少数科技股的依赖过大。标普 500 期货下跌 0.37%，显示投资者在地缘政治风险和通胀担忧中可能保持谨慎</p>

<p>The S&amp;P 500 closed above the 7,500 level for the first time on Thursday, but Polymarket traders are overwhelmingly betting the benchmark index will open lower on Friday as investors digest stretched valuations, AI-driven market concentration and developments from the ongoing U.S.-China summit.</p>
