AI Reduces Valuations Across Software And Chips
7.1
On December 7, 2025 the author recommended market weighting rather than overweighting the Magnificent-7 after their combined S&P 500 market-cap share fell from 46.7% on November 5, 2025 to 43.9% by Monday. Despite forward earnings rising to a record 39.8%, the combined forward P/E dropped from 28.9 to 24.3, reflecting AI-driven competition and investor multiple compression across software and chips.
Key Points
- 1Show market-cap decline: Magnificent-7 fell from 46.7% to 43.9% of S&P 500.
- 2Explain valuation compression: forward P/E dropped from 28.9 to 24.3 despite record earnings.
- 3Recommend market-weighting; semiconductor-equipment stocks benefit from durable demand and limited competition.
Scoring Rationale
Actionable market analysis with specific valuation data; limited novelty and single-source commentary constrain broader impact.
