12 Best Performing Semiconductor Stocks to Invest In

9. Allegro MicroSystems Inc. (NASDAQ:ALGM)

6-Month Performance: 79.08%

Allegro MicroSystems Inc. (NASDAQ:ALGM) is one of the best performing semiconductor stocks to invest in. On July 2, Allegro MicroSystems has introduced the A81415, the industry’s first ASIL-D-certified PMIC that integrates a wheel-speed sensor interface. Designed for electromechanical braking/EMB systems, this single-chip solution eliminates up to nine external components and unlocks over 50% more board space, helping automotive designers streamline brake-by-wire architectures while reducing bill-of-materials costs.

By consolidating power management and sensor decoding, the A81415 reduces latency in safety-critical loops and frees up MCU bandwidth for faster braking responses. The device is built to handle the rigorous demands of corner module electronics, offering a fail-operational foundation that is thermally robust and vibration-resistant, specifically tuned to support high-resolution sensing and clamping-force signals.

The A81415 provides a clear migration path for moving from 12V to 48V braking systems without requiring bulky external protection. By acting as a cohesive system for both sensing and power, it enables Tier 1 suppliers to develop simpler, more scalable foundations for next-generation software-defined vehicles, ensuring reliability where it is needed most at the wheel.

Allegro MicroSystems Inc. (NASDAQ:ALGM) develops and manufactures sensor integrated circuits and application-specific analog power ICs.
