My top 3 small-cap semiconductor picks in 2025

The semiconductor market’s spotlight has been on giants like $NVIDIA (NVDA.US)$ , $Broadcom (AVGO.US)$ , $Taiwan Semiconductor (TSM.US)$ , $Advanced Micro Devices (AMD.US)$ & $ASML Holding (ASML.US)$ , overshadowing small-cap players.

$Aehr Test Systems (AEHR.US)$ has carved out a niche so precise that it almost defies replication. Focused on testing and burn-in solutions, Aehr ensures the reliability of silicon carbide (SiC) devices -- components essential for EVs and renewable energy systems. SiC’s role in these markets is both foundational and expansive, as demand for high-efficiency power systems surges. Aehr’s low-cost wafer-level testing stands out, offering manufacturers a critical tool to improve yields and cut costs. Yet, Aehr’s story isn’t without complexity: --revenue growth has been volatile, oscillating with market forces. Even so, the company’s FOX platform is a linchpin, poised to capitalize on SiC’s growing ubiquity across sectors like EVs, solar energy, and even AI hardware.

On another front, $indie Semiconductor (INDI.US)$ diversified portfolio -- encompassing ADAS systems, radar, LiDAR, and electrification technologies -- aligns perfectly with the industry's trajectory toward smarter, safer, and more connected vehicles. Indie’s strategic backlog surpasses $7B, a figure that underscores the scale of its ambitions. With revenue growth projected at 40% in 2025, the company is navigating the intricate web of automotive semiconductors with finesse. Its ability to integrate all four key ADAS sensor modalities gives it a rare advantage, positioning it as a sought-after partner for automakers designing the next generation of vehicles. Still, challenges loom -- concentrated exposure to China and potential bottlenecks in EV adoption could impede progress. Yet, indie’s strong pipeline and operational resilience suggest it is well-equipped to weather these uncertainties.

Meanwhile, $Navitas Semiconductor (NVTS.US)$ is rewriting the rulebook on power electronics through its pioneering work in gallium nitride (GaN) technology. GaN’s efficiency and speed eclipse traditional silicon solutions, making it a cornerstone for applications spanning mobile devices, data centers, and EVs. With over 60 design wins in data centers signal its disruptive potential, and a partnership with Infineon amplifies its credibility. This collaboration, strategically vital, could accelerate GaN adoption while positioning Navitas as an acquisition target. However, near-term hurdles such as revenue stagnation and high cash burn cannot be ignored. Even so, the company's focus on cutting-edge platforms for AI and EVs paints a promising picture of future growth.
