Why ALGM stock is up today

Allegro Microsystems stock rose 7.61% to $39.15 in morning trading as RBC Capital initiated coverage with an Outperform rating. The move followed a positive analyst review and came amid a broader 63% rally in the stock over recent months. The stock opened with a 2.8% gap up and reached an intraday high of $39.59 shortly after the market opened.

What Happened

RBC Capital started coverage on Allegro Microsystems with an Outperform rating and a price target of $50. This marked the second major firm to issue a bullish rating on the stock in a short period. Earlier in the week, Mizuho maintained an Outperform rating but lowered its price target to $58. Meanwhile, Citi downgraded the stock to Neutral, citing the recent 63% rally but raising its price target. The mixed analyst sentiment did not dampen the stock’s upward momentum as RBC’s initiation appeared to drive immediate buying interest.

Retail traders on r/wallstreetbets have also shown interest in Allegro Microsystems, with some calling it a compounder in the industrial and AI sectors. The stock is currently trading near the top of its 52-week range and has printed four fresh 52-week highs in recent days.

What The Data Shows

The stock’s intraday session showed a sharp opening gap up and a quick move to a high of $39.59, indicating strong early demand. Volume was light at 0.1 million shares, which is 0.0 times the 3-month average. The stock has a market cap of $6.8 billion and trades at a P/E ratio of 514.5, reflecting high growth expectations. Revenue has grown 24.2% in the trailing twelve months, but net margins remain low at 1.5%. Insiders sold $147,000 worth of shares in the last 90 days, with the most recent sale on August 18.
