IBM Stock Slumps 1.64% Amid AI Valuation Fears and Tech Sector Shift

International Business Machines Corp. (IBM) shares slipped 1.64% in Tuesday’s trading, closing near $132.40 after a session marked by broad tech‑sector unease and renewed worries about the pricing of artificial‑intelligence investments. The decline came despite the company’s recent push to highlight advances in hybrid cloud infrastructure and quantum‑computing research, suggesting that investors are weighing near‑term market sentiment against longer‑term innovation bets.

Key Developments
The drop followed a mixed earnings preview from IBM’s cloud and AI division, which reported slower‑than‑expected growth in its Watson AI services while noting strong demand for Red Hat OpenShift platforms. Analysts at JPMorgan noted that the firm’s guidance for FY2025 revenue remained flat, prompting a reassessment of its valuation multiples.

IBM’s stock also reacted to a downgrade from Morgan Stanley, which cut its rating to “Equal‑Weight” citing “valuation pressure” as AI hype continues to inflate peer multiples.

Industry Analysis

While firms such as Nvidia and Microsoft have seen their shares rally on AI optimism, legacy technology providers like IBM face skepticism about their ability to monetize AI at scale.
