# 隨着收益率達到多年高點，標普 500 的集中度也達到了峯值

Record stock concentration: Nvidia and Apple now make up over 15% of the S&P 500, surpassing historical peaks seen during the dot-com bubble. Yields climb sharply: The 30-year Treasury yield hit 5.20%, a 19-year high, as markets brace for prolonged restrictive Fed policy amid sticky inflation. Correction risk ahead: BofA’s survey shows record equity overweight and low cash levels, signaling potential for profit-taking in early June.
