I would watch the 10-year yield; crossing 4.5% historically causes short-term stock wobbles. The strong US economy is why rate cuts have been priced out and rate hikes are on the table. A new Fed chairman signals short-term volatility. For long-term portfolios, we lean into US strength.
We like hyperscalers but incrementally tilt to other sectors and asset classes. If economy is strong, lean where there is margin of safety, like EM debt and emerging markets. Diversify away from just SPY and QQQ.
