In this article, we will discuss the 12 Best Performing Semiconductor Stocks to Invest In.

On July 8, Anastasia Amoroso, Chief Investment Strategist at Partners Group, joined BNN Bloomberg to discuss the current volatility in the semiconductor sector and her broader, bullish outlook on the AI trade. Amoroso addressed the recent sell-off in chip stocks, sparked by a decline in Samsung despite the company reporting a 19-fold increase in profits. She explained that this market movement is not a reflection of disappointing fundamentals in memory chips, but rather a result of traders taking profits after a stratospheric run that saw the SOX index rise by 90% before the recent pullback. She noted that the semiconductor trade has become heavily leveraged, with significant margin debt accumulated in markets like Korea and Taiwan, making profit-taking a natural response. Despite this, she remained optimistic, arguing that the fundamental narrative of AI remains unchanged, with global adoption, monetization, and innovation (what she describes as a flywheel effect) all accelerating.

Amoroso explained that the semiconductor industry is undergoing an evolution as the bottleneck for AI infrastructure migrates. While the initial race focused on compute power for training AI models, the industry is now moving into the inference stage, where memory (including short-term, long-term, and high-bandwidth memory) has become critical for AI servers and data centers. She noted that current industry analysis suggests it will take 18 to 24 months to clear this memory shortage. Furthermore, because memory chip makers are increasingly signing long-term contracts with customers, she suggested that the space may be shifting from a traditionally cyclical sector into a long-term secular growth area, which could potentially warrant higher valuation multiples for these stocks.

Regarding the massive CapEx spending by hyperscalers, Amoroso acknowledged that potential roadblocks exist, such as scrutiny over free cash flow and widening credit spreads in debt markets. However, she believes investors are generally encouraged by evidence of monetization, pointing to cloud revenue growth of over 20% year-over-year and a cloud backlog reaching $1.5 trillion. She also notes that companies are successfully utilizing internal AI capabilities to optimize recommendation engines in e-commerce and digital advertising to drive sales and revenue.

Against this backdrop, let’s take a look at some of the best performing semiconductor stocks to invest in.
