Overview
- The S&P 500’s Shiller CAPE sits near its second‑highest level historically, a reading that matched extremes seen at the 2000 dot‑com peak and is widely used to flag long‑term valuation stress.
- Much of the recent runup in the index has been driven by a small group of AI‑linked mega‑cap stocks, leaving the benchmark concentrated and more vulnerable if those names stumble.
- Geopolitical friction involving the United States and Iran has pushed oil above $100 per barrel, which has fed a sharp rise in energy costs and helped lift headline inflation.
- The Federal Reserve raised interest rates by 25 basis points in September and signaled the possibility of another hike this year, tightening the policy backdrop investors face.
- Advisers now recommend defensive positioning such as broader diversification, shorter‑duration fixed income or cash equivalents, dividend names and non‑U.S. exposure to reduce downside risk.
