Not Just NVDA: 3 Semiconductor Stocks Struggling This Quarter

While the broader semiconductor sector benefits from AI tailwinds, Texas Instruments, Marvell Technology, and ON Semiconductor are underperforming due to specific challenges. Texas Instruments faces tariff-related pressures and weakness in its industrial and automotive segments, overshadowing positive earnings. Marvell Technology, despite strong AI data center exposure and record revenue, saw its stock decline nearly 40% YTD after delivering cautious guidance on sequential data center growth and grappling with a high 73x forward earnings valuation. Meanwhile, ON Semiconductor is experiencing margin compression and declining sales in its automotive division amid macro headwinds.

Analysis

Despite a robust AI-driven rally in the semiconductor sector, a clear performance divergence is evident, with several major chip companies underperforming due to specific, non-AI related headwinds. Texas Instruments (TXN) is lagging, with its stock down nearly 10% in the last three months, as tariff concerns and exposure to the cyclical automotive and industrial sectors overshadow its top and bottom-line earnings beats in Q1 and Q2. The quality of its recent sales growth is also in question due to potential customer stockpiling, a sentiment reinforced by management's cautious Q3 guidance of $4.45 billion to $4.8 billion. In contrast, Marvell Technology (MRVL), a direct AI-play, has seen its stock fall nearly 40% year-to-date despite a 57% year-over-year revenue increase in Q2. The decline was triggered by guidance for flat sequential data center revenue in Q3—a segment accounting for 70% of sales—and a lofty valuation at 73 times forward earnings, which led to an 18% post-earnings stock drop and multiple analyst price target reductions. Lastly, ON Semiconductor (ON) is struggling with deteriorating fundamentals linked to the automotive market, posting a 15% year-over-year sales decline and a 240 basis point quarter-over-quarter drop in gross margin in Q2. Its performance is directly tied to the slowing EV market, resulting in a 20% year-to-date stock decline and a consensus 'Hold' rating from analysts.

Key Decisions for Investors

• Investors in Texas Instruments should prioritize monitoring U.S.-China trade developments and automotive/industrial inventory cycles, as these macro factors are currently negating the company's positive earnings results.
• Marvell Technology presents a high-risk, high-reward profile; its sharp pullback could be a buying opportunity for those with a long-term bullish view on AI data center growth, but this must be weighed against its high 73x forward P/E and the immediate headwind of tempered growth guidance.
• For ON Semiconductor, any potential investment thesis hinges on a recovery in the automotive sector, so investors should look for signs of strengthening EV demand and inventory normalization before considering a position, given the significant margin pressure and sales decline.
• The varied performance of these firms highlights the importance of moving beyond broad sector themes and conducting specific due diligence on sub-sector exposure, as headwinds in areas like automotive and industrials are creating significant laggards in an otherwise strong industry.
