Memory chip stocks have won investors' attention thanks to the artificial intelligence (AI) boom. Micron Technology and Sandisk have produced tremendous gains over the past year, and investors are scouring the market for smaller memory chipmakers that can outpace the S&P 500.
Silicon Motion Technology (NASDAQ: SIMO) may be a worthy candidate. This chip stock has almost tripled in value year-to-date, but its market cap is still under $10 billion and its valuation metrics are reasonable given its growth efforts. All of the growth is driven by fundamentals, and the company's guidance implies that revenue growth will continue to accelerate.

NAND flash controllers are a critical part of the memory boom
Silicon Motion Technology supplies NAND flash controllers, which act as the brains behind solid-state storage devices and systems that use NAND flash memory. These NAND flash controllers are central parts of Sandisk's storage products, which have been flying off the shelves due to the AI boom.
The company also lists Micron, SK Hynix, and Samsung as customers. Each of these memory chipmakers has posted superb revenue growth and optimistic guidance in recent quarters, and Silicon Motion Technology has been a major beneficiary.
Revenue more than doubled year over year in Silicon Motion Technology's second quarter results. Sales increased by 32% sequentially and smashed guidance in the process. The company also forecast up to $541 million in Q3 sales, representing a 20% sequential improvement.
Silicon Motion Technology is already posting impressive results while staying under the radar. Its fundamental growth is fueled by the leaders of the AI boom, who are securing multi-year deals with their biggest customers.
Momentum is expected to continue
Silicon Motion Technology CEO Wallace Kou told investors that they expect momentum to "continue into the second half" of 2026 and that the company is "building a resilient platform for sustainable, high-quality revenue and profitability growth for years to come."
It further dispels concerns about a cyclical downturn for memory chips. The AI boom is still in its early innings, with agentic AI, humanoid robots, and self-driving vehicles on the horizon. The company said in its Q2 press release that it is "well positioned across every AI market, including AI data center, AI server, edge AI, and physical AI."
Incredible guidance and an upbeat outlook for future quarters suggest that Silicon Motion Technology can continue to outperform the S&P 500. Few companies can compete with Silicon Motion Technology's product portfolio and customer connections. This company is an example of focusing on strengthening fundamentals rather than believing investors missed out on the rally just because shares have almost tripled over the past year.
