標普 500 指數

思科

核心美國價值 ETF - iShares

<p>Polymarket 交易者預測，2026 年 5 月 15 日標普 500 指數將低開，此前該指數創下 7,500 以上的歷史收盤紀錄。儘管上漲了 0.77% 至 7,501.24，但對估值過高和市場集中度的擔憂依然存在。強勁的企業盈利，尤其是思科系統的表現，支撐了股票市場，但策略師警告稱，市場對少數科技股的依賴過大。標普 500 期貨下跌 0.37%，顯示投資者在地緣政治風險和通脹擔憂中可能保持謹慎</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>
