Summary:
The U.S. third-quarter earnings season shows widespread earnings growth across market caps, with AI continuing to dominate profit expansion. Small-cap companies are recovering from wage and interest rate pressures, while mega-cap tech firms demonstrate earnings catching up to market valuations. AI-driven investments now account for significant GDP growth, comparable to historic infrastructure cycles like railroads and the internet.
What This Means for You:
- Diversify strategically: While tech drives earnings, small-cap recovery signals opportunities beyond AI-focused mega-caps.

- Track AI productivity metrics: Future stock performance hinges on whether AI investments translate into measurable economic output.
- Watch tariff impacts: Companies like GM show tariff mitigation strategies can significantly affect post-earnings performance.
