AI Chipmaker Stock Sell-Off: Here Are My Top 2 Semiconductor Stocks to Buy Now

In This Article:

In January, China's DeepSeek AI sparked a sell-off in artificial intelligence (AI) stocks after sharing breakthroughs in developing highly efficient training and inference algorithms for large language models. In other words, DeepSeek's AI models showed maybe big tech companies don't have to spend hundreds of billions of dollars on the most advanced GPUs available for their data centers.

The sell-off accelerated recently after Nvidia (NASDAQ: NVDA) reported earnings and President Donald Trump imposed additional tariffs on China with new tariffs on Mexico and Canada. While Nvidia's earnings results beat analysts' published expectations, investors weren't fully reassured that DeepSeek's efforts and the uncertain economic environment wouldn't slow down Nvidia's rapid growth.

Many other semiconductor stocks have seen their share prices decline along with Nvidia's recently. A couple of those stocks look particularly appealing at these lower prices. These are my top two semiconductor stocks to buy now.

1. Taiwan Semiconductor Manufacturing

Taiwan Semiconductor Manufacturing (NYSE: TSM), known as TSMC, is the largest chip manufacturer in the world. When Nvidia needs its latest and greatest GPUs printed and packaged, it contracts with TSMC because, as Nvidia CEO Jensen Huang said, "It's the world's best by an incredible margin."

Indeed, TSMC's technology lead is a huge advantage that helps it attract the world's biggest customers like Nvidia and Apple. As a result, it captures over 60% of the spending on semiconductor fabrication, and that percentage is growing as companies demand more high-end AI chips that only TSMC can produce. With such a large revenue base, TSMC is able to reinvest much more than its competitors in research and development, ensuring it maintains and extends its technology lead.

TSMC is also able to invest ahead of the growth it sees in the market. It announced a big step up in capital investments for 2025 in January, forecasting $38 billion to $42 billion in spending this year. That's up 34% from 2024 at the midpoint.

Management is historically very good at forecasting demand and investing appropriately to meet those expectations. However, semiconductor manufacturing is inherently a cyclical business. If demand drops significantly, TSMC still has a lot of overhead to keep its manufacturing facilities running.

The company recently announced plans to invest $100 billion in the United States. That's on top of its plans to expand its facilities in Arizona, the first of which entered high-volume production in late 2024. The new facilities will include TSMC's most advanced technology. It's possible TSMC's investment plans will help it avoid targeted tariffs impacting its business and those of its customers.
