S&P 500 companies with this AI strategy dramatically outperformed their peers: New data

The article discusses a new Gregory study on AI strategy rollouts across 449 companies from 2022 to 2025, finding that the quality of a company’s AI announcement and follow-through can materially affect stock performance. Companies scored highly on factors such as CEO ownership, specific use cases, 90-day execution, board governance, and tier-1 media coverage. Among the top-scoring firms, only 13 reached the highest tier. Those Tier 1 companies outperformed sector benchmarks by an average of 10.8% in alpha over 90 days after the announcement, while Tier 3 companies underperformed by 2.2%. The piece suggests that how companies communicate AI initiatives to investors and the market can influence valuation and relative returns, reinforcing AI as a market-moving theme.
