CEO selling within days of a strong earnings beat is a cautionary signal. Monitor for follow-on sales exceeding 0.1% of market cap, which would escalate bearish implications. The stock's strong earnings momentum may limit downside, but the insider skew warrants hedging or trimming near $47-$48 resistance levels.
Price Chart
Executive Summary
A cluster of insider open-market sales at Allegro MicroSystems (ALGM) totaling ~$2.61M occurred within days of a strong earnings beat and positive guidance. CEO Michael Doogue sold ~$1.42M, a Director sold ~$760K, and the GC sold ~$425K. These are not 10b5-1 pattern sales and represent 0.034% of the $7.7B market cap — a small but notable signal given the C-suite participation. The cross-filing actuarial calibration amplifies this pattern (cluster + earnings context is an AMPLIFIER with PMI=2.50, q=0.000).
Key Financial Metrics
Key Facts
- CEO Doogue sold 30,100 shares for ~$1.42M at $47.23 on May 11, days after Q4 FY2026 earnings beat.

- Cluster follows strong Q4: revenue $243.2M (+26% YoY), non-GAAP EPS $0.17 beating consensus $0.16.
- Q1 FY2027 guidance of $245-255M sales and $0.19-0.23 EPS implies continued growth, yet insiders sold.
- Non-cash awards (grants, tax-withholding surrenders) were also filed on May 13/16 but are not open-market sales.
- Cross-filing calibration AMPLIFIES the insider-cluster + earnings-context combination (PMI=2.50).
Financial Impact
Insider sales of ~$2.61M represent 0.034% of market cap — proportionally small but noteworthy due to CEO participation and timing right after earnings.
Risk Factors
- CEO and GC sold immediately after positive earnings — potential peak-signaling risk.
- Sales are not part of a 10b5-1 plan pattern (single lump trades), increasing informational concern.
- If other C-suite insiders join selling, bearish signal could intensify.
- Stock has rallied ~26% YoY — insider sales may signal valuation exhaustion.
