IBM Stock Is Outperforming Nvidia's This Year. Are Shares a Buy?

IBM is experiencing a notable resurgence, with its stock up 45% year-to-date, driven by a successful strategy focusing on specialized enterprise AI solutions and a significant breakthrough in quantum computing. The company's "AI book of business" grew 26% year-over-year to $9.5 billion in Q3 2025, contributing to improved margins and a raised 2025 revenue outlook, alongside projected internal AI-driven savings of $4.5 billion annually. Additionally, IBM's development of a quantum error correction algorithm, which runs on standard chips and is 10x faster than required, solidifies its "pole position" in the quantum computing race, suggesting a strong investment case given its growth, value, and dividend yield.

Analysis

IBM has demonstrated a significant resurgence, with its shares climbing 45% year-to-date, notably outperforming Nvidia's 42% return, driven by a strategic pivot towards specialized enterprise AI solutions. CEO Arvind Krishna's decision to focus on smaller, client-tailored AI models, prioritizing accuracy and cost-efficiency over large generalist models, appears to be yielding substantial results.

The company's "AI book of business" expanded 26% year-over-year in Q3 2025, reaching $9.5 billion, reflecting robust growth in software (10%) and infrastructure (17%) revenues. This operational strength has led management to raise its 2025 revenue growth outlook to over 5% and improve gross profit margins by 1.2% to 57.3%, alongside projected internal AI-driven annual savings of $4.5 billion.

Further bolstering its market position, IBM announced a significant breakthrough in quantum computing, developing an error correction algorithm that runs on standard semiconductor chips and is 10 times faster than required. This innovation, which caused a 7% surge in IBM shares, solidifies its "pole position" in the global quantum race, with plans for a 20,000x more powerful Starling quantum computer by 2029.

Despite hitting an all-time high, IBM's stock maintains an attractive valuation with a price-to-earnings ratio of 24, well below the S&P 500's 31, and offers a competitive 2.2% dividend yield. Consistent earnings beats over the last four quarters further underscore the company's positive trajectory and strong investment case.

Key Decisions for Investors

• Consider a long position in IBM, given its strong year-to-date performance, strategic success in enterprise AI, and leadership in quantum computing.
• Monitor the continued growth of IBM's "AI book of business" and the execution of its quantum computing roadmap as key indicators of sustained momentum.
• Evaluate IBM's attractive valuation (P/E of 24) and 2.2% dividend yield, which provide a compelling blend of growth potential and income generation compared to broader market indices and tech peers.
