Most Popular Narrative: 4.3% Overvalued

Monolithic Power Systems’ latest consensus narrative assigns it a fair value of $867, slightly below its last close of $904.44. The narrative describes robust growth drivers, but the gap suggests that high performance may be fully factored into today’s price.

Expectations for long-term automotive segment growth, driven by secular shifts toward EVs, zonal and 48V/800V in-car architectures, and increased semiconductor content per vehicle, are supporting high valuation multiples. However, these trends may already be fully priced in, leading to risk of eventual slower revenue growth as the rollout curve flattens.
