Why Allegro MicroSystems (ALGM) Shares Are Falling Today

What Happened?

Shares of chip designer Allegro MicroSystems (NASDAQ:ALGM) fell 6.8% in the afternoon session after the company reported quarterly financial results that disappointed investors on profitability. The chip designer announced revenue of $203.4 million, a 22% increase from the previous year, which surpassed analyst forecasts. Allegro also issued an optimistic outlook for the next quarter, expecting revenue to land between $205 million and $215 million. However, investors focused on the company's bottom line. The reported GAAP loss of $0.07 per share fell significantly short of Wall Street's expectations. This earnings miss appeared to overshadow the strong sales growth and positive guidance, prompting a sell-off in the stock.

What Is The Market Telling Us

Allegro MicroSystems’s shares are extremely volatile and have had 37 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 8 days ago when the stock dropped 6.4% on the news that industry bellwether Texas Instruments signaled softer demand and issued a cautious outlook. Texas Instruments, a key chipmaker for various industries, sparked concern after it provided a weaker-than-expected forecast for the remainder of the year. Analysts on the company's earnings call noted a "tone shift" from executives regarding the semiconductor recovery cycle compared to previous quarters. The change in messaging from a major industry player created uncertainty about the health of the overall chip market. This cautious sentiment appeared to weigh on related stocks, as investors reassessed the sector's near-term growth prospects.

Allegro MicroSystems is up 38.3% since the beginning of the year, but at $31.54 per share, it is still trading 15.9% below its 52-week high of $37.51 from July 2025. Investors who bought $1,000 worth of Allegro MicroSystems’s shares at the IPO in October 2020 would now be looking at an investment worth $1,782.

While Nvidia and AMD are trading close to all-time highs, we prefer a lesser-known (but still profitable) semiconductor stock benefiting from the rise of AI.
