Fundamentals
Valuation and ratings
Diodes Incorporated trades at $96.79, which is 30% above the $67.38 our fair value estimate puts on the business. On that measure it screens as expensive, which is not the same as saying it will fall.
Our moat model scores it 43 out of 100, which is little in the way of a moat. A moat is a structural reason competitors cannot take the profits away, and it matters more to a long holding period than any single quarter's numbers do.
It changes hands at 43.5 times earnings. Be careful reading that in isolation: for a cyclical business a low P/E arrives at the top of the cycle, when profits are peaking and about to fall, which is exactly when the shares look cheapest and are not.

Estimates are the published analyst consensus and move often. An earnings date is scheduled, not certain, and a share tends to reprice most violently on the day itself.

A word of warning on reading these figures: a 13F reports the market value of a holding, so a fund that traded nothing at all still appears to have sold when the price fell. We found 102 companies where the standard reading gives the opposite answer. Only the share count is honest.

Common questions
Is Diodes Incorporated (DIOD) undervalued?
Against our fair value estimate of $67.38, DIOD at $96.79 is 30% above fair value. That is one model's answer, not a recommendation. It is built from normalized earning power with growth capped deliberately low, which understates companies whose value is mostly future growth.
Which funds own DIOD?
10 of the institutions we track reported a position in DIOD in their most recent SEC 13F filing. A 13F is filed up to 45 days after quarter end, so it tells you what a fund held then, not what it holds now.
What is DIOD's P/E ratio?
DIOD trades at 43.5 times earnings. A low P/E is not automatically cheap: on a cyclical company it is usually a warning that earnings are at a peak.
