TSMC's Record Profit Meets Market Skepticism: Time to Buy?

Taiwan Semiconductor Manufacturing Corporation (TSM) reported third-quarter earnings on Thursday that beat expectations across the board. Revenue surged 50.9% year-over-year to $46.7 billion, surpassing the consensus estimate of $45.7 billion. Adjusted earnings per share jumped to $4.60 from $2.92 a year ago, also topping forecasts.

The company's profitability metrics expanded significantly, with gross margin rising to 66.4% from 59.5% and operating margin reaching 58.7%. This demonstrates TSMC's pricing power and operational efficiency. For the first time, 3-nanometer chips became the largest revenue contributor at 33% of sales, while advanced technologies (7nm and below) accounted for 79% of total revenue.

High-performance computing (HPC), which includes AI chips, continued to gain share, representing 68% of revenue. CEO C.C. Wei highlighted that demand for AI accelerators is driving HPC growth and expressed optimism about the emerging agentic AI market, stating that recent developments are 'very positive to AI's long-term demand outlook.'

Despite these strong results, TSMC's stock fell 2.2% on Thursday, at one point dropping more than 5%. The decline came amid a broader sell-off in AI-related stocks, with the VanEck Semiconductor ETF down 8.2% for the week. Concerns about rising interest rates, circular financing deals, and competition from China weighed on the sector.

Additionally, CEO Wei warned that 'consumer and price-sensitive end market segments are being challenged due to the impact of rising component prices and macroeconomic uncertainties,' referring to surging memory prices and weakness in smartphone and PC demand. However, he noted that the AI market remains insulated from these headwinds.

TSMC's earnings report is a critical bellwether for the entire semiconductor industry and the broader AI trade. The company's ability to consistently beat expectations and expand margins underscores its dominant position as the world's largest contract chipmaker. However, the stock's negative reaction reveals that investors are currently more focused on macroeconomic risks and sector-wide headwinds than on individual company fundamentals.

The sell-off in AI stocks this week reflects growing skepticism about the sustainability of the AI boom. Rising bond yields have made growth stocks less attractive, while concerns about circular financing deals—where companies invest in each other to fuel demand—have raised questions about the underlying strength of AI demand. Competition from China is also a persistent overhang.

TSMC's warning about consumer and price-sensitive segments adds another layer of concern. While AI demand is 'extremely robust,' weakness in smartphones and PCs could offset some of the AI-driven growth. This dichotomy suggests that the semiconductor cycle may be bifurcating, with AI chips thriving while traditional markets struggle.

For long-term investors, TSMC's valuation remains attractive. At a price-to-earnings ratio of just 32, the stock trades at a modest premium to the S&P 500, despite its superior growth prospects. The company's wide economic moat, driven by its technological leadership and scale, positions it well to benefit from secular trends like AI, robotics, and the Internet of Things.

The current sell-off appears to be driven by sentiment rather than fundamentals. As the AI trade matures, investors may rotate back to quality names like TSMC that have proven execution and strong cash flows. The company's plans to expand capacity, including in the U.S., further support its long-term growth trajectory.
