Highlights

How we pick these

Strengths

  • Fast growth. Revenue grew 17.8% over the last 12 months, against a median of 13.7% for semiconductor companies we cover.
  • Net cash. Cash exceeds long-term debt by $0.4bn.
  • Estimates rising. Analysts' consensus for next year's earnings per share has risen 11.2% over 90 days.

Things to watch

  • Priced above our value. The share price of $79.72 is 40% above our value per share of $48.
  • High earnings multiple. The shares trade at 43 times the last 12 months' earnings, so expectations are demanding.
  • Volatile shares. Over the past year the shares showed annualised volatility of 68% and a beta of 2.6 against the S&P 500.
  • Insiders selling. 8 insiders sold $17M of stock over the past 365 days and none bought (0% under pre-set trading plans).
  • Below peers: gross margin. Gross margin of 31.7% ranks 55 of 73 semiconductor companies we cover (median 48.3%).

Valuation

Diodes Inc valuation models and calculator

What the price is pricing in

The share price implies about 20.9% a year of cash-flow growth for five years.That is faster than the -2.0% a year revenue growth Diodes has delivered.

  • Priced in20.9%
  • Last 12 months17.8%
  • 3 years a year-5.7%
  • 5 years a year-2.0%

Our cash-flow model with every input fixed except growth over the next five years, solved for the growth at which the model value equals the share price ($84.34, Nov 3, 2026). Cash-flow growth then fades to 2.5% a year; discount rate 8.5%. Delivered figures are revenue growth from SEC filings.

How we got here: a discounted-cash-flow model of Diodes Inc's free cash flow after stock-based pay with after-tax interest added back ($74.3M, FY2026 Q2 TTM), growing 20.7% and 9.6% in the next two years (forecasts, guidance and its record), then back to 6% by year five, and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$38–~$61 ; that spread sets a 15% margin before we rate Buy or Sell.

Produced by Fundamentalytics' automated valuation model on November 3, 2026, using delayed market prices. Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Our value per share comes from a discounted-cash-flow model of Diodes Inc's free cash flow after stock-based pay ( $74.3M, FY2026 Q2 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

Valuation models

We value Diodes Inc as an operating company, with every model that fits that kind of business. Cost of equity 12.7%: the 10-year Treasury yield (4.9%) plus a beta of 1.73 times a 4.5% equity risk premium.

Different models fail in different ways, so where several apply we average them rather than trust one.

  • Cash conversion 14 / 20

    Free cash flow was positive in 9 of 10 years, at a median 9.2% of revenue.

  • Discipline 18 / 20

    The diluted share count fell 4.5% over five years; stock-based pay has been a median 1.8% of revenue.

AI disruption exposure: Low. In this industry, the business rests on physical assets, regulated networks or products AI itself depends on.

Options strategies

All options ideas

How Diodes Inc’s listed options are priced, and three ways to use them that follow from our valuation. Quotes are delayed, read November 2, 2026. Check the live chain at your broker before trading.

Cash-secured put

Not offered: rated Sell.

We suggest selling a put only on well-rated companies, at a strike where the price you would pay if assigned (strike less premium) is at or below our fair value.

Covered call

Not offered: no liquid call at or above our price target — the model says the upside is worth more than any listed strike.

For holders: sell a call at a strike at or above our fair value, so the shares are only sold at a price the model calls full value.

Collar

Not offered: no liquid put and call pair for the same expiry.

For holders of a stock trading at or above our fair value: buy a put for a floor and sell a call to pay for it.

General research, not personal advice. Options can lose you more than you expect and are not suitable for everyone: put sellers can be made to buy shares that keep falling, call sellers give up gains above the strike, and results or news can move prices sharply. Chances shown are approximations from each option’s delta. Spreads, fees and early assignment are not modelled.
