Diodes (DIOD): Assessing Valuation After New AP61406Q Automotive Power Converter Launch

Diodes (DIOD) just rolled out its AP61406Q automotive DC-DC buck converter, a compact, programmable power chip aimed at infotainment, instrument clusters, telematics, and ADAS, giving investors another data point on its auto strategy.

See our latest analysis for Diodes.

The AP61406Q launch comes as Diodes’ 7 day share price return of 13.78% has injected some welcome momentum into a stock whose 1 year total shareholder return is still negative at 13.49%. This hints that sentiment may be stabilizing rather than surging.

If this kind of targeted auto exposure appeals to you, it could be worth scanning other listed auto chip and component players via our auto manufacturers and comparing how their growth stories stack up.

Yet with shares still down double digits over the past year despite solid revenue and earnings growth, investors have to ask: Is Diodes quietly undervalued here, or is the market already pricing in its next leg of automotive driven expansion?

Most Popular Narrative Narrative: 10.4% Undervalued

With Diodes last closing at $52.58 versus a most popular narrative fair value near $58.67, the valuation hinges on aggressive profit recovery and richer future multiples.

Rapid electrification in automotive, particularly EVs in China, is leading to growing content per vehicle and an expanding set of design wins for Diodes' automotive-qualified products (such as protection devices, LED controllers, and power management ICs). This supports higher average selling prices and future margin expansion.

Strategic focus on new product introductions, especially in high-margin analog, mixed-signal, and power management segments, positions Diodes to benefit from product mix improvement. This should translate into structurally higher gross and operating margins over time.

Read the complete narrative.

Curious how moderate revenue growth, sharply higher margins, and a reset earnings multiple supposedly add up to that upside target? The narrative’s projections might surprise you.

Result: Fair Value of $58.67 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, elevated inventory and heavy Asia exposure mean that any demand wobble or geopolitical shock could quickly challenge the upbeat, automotive-driven thesis.

Another Angle on Value

While the popular narrative leans on future earnings growth, today’s price already embeds a rich 38x earnings multiple versus the US semiconductor average of 37.5x. Even if a fair ratio of 42.9x suggests some upside, that premium leaves little room for execution slip ups, does it not?
