AI Summary

5.0
Neutral

ALGM's investment case has shifted from a simple automotive rebound to proving that strong revenue recovery and new safety/power design wins can translate into durable margin expansion, but its premium valuation leaves little room for execution missteps. Investors should wait for multiple quarters of sustained growth, rising margins, and tangible brake-by-wire production traction before treating the selloff as a buying opportunity.
