AI Summary

6.0
Neutral

SMTC has shifted from a recovery trade to a high-stakes AI networking execution bet: its recent profitability and cash generation improve credibility, but the stock already prices in much of the upside, so investors need several more quarters of proven 800G/1.6T ramp strength and stable support around 125–128 before getting more constructive.
