At a share price of $125.92, Semtech has seen sharp swings, with the share price return declining 9.2% over the past day and 15.9% over the past month, yet rising 24.3% over 90 days and 67.3% year to date.

Most Popular Narrative: 38.5% Undervalued

Semtech’s most followed narrative pegs fair value at $204.83, well above the last close at $125.92, which puts a spotlight on what is driving that gap.
