Data as of 2026-09-08. NASDAQ, United States. Sector: Technology / Semiconductors & Semiconductor Equipment. Price $91.79, market value $4.2 billion.

## Valuation
- **P/E (trailing): 49.3×** (5-yr avg 29.7×, 3-yr avg 38.6×). Diodes Incorporated trades at 49.3× trailing earnings, well above its own five-year average of 29.7×: investors are paying up relative to the company's past. The Technology median in the September 2026 study was 32.1×. Forward P/E is 15.7×, lower than trailing, so analysts expect earnings to grow.
- **PEG: 0.31**. A PEG of 0.31 means the P/E is low relative to expected earnings growth: the market is not paying much for that growth.
- **Price / sales: 2.6×**. Each dollar of revenue is priced at 2.6×.
- **Price / book: 2.2×**. The shares trade at 2.2× book value; book value is a meaningful part of the valuation.
- **Free-cash-flow yield: 3.4%** (5-yr avg 4.0%). Free cash flow equals 3.4% of the market value, in line with its five-year average of 4.0%.
- **Earnings yield: 2.0%**. The inverse of the P/E: 2.0% of the price is earned each year.

## Profitability
- **Gross margin: 31.7%**. Diodes Incorporated keeps 31.7% of revenue after the direct cost of what it sells.
- **Operating margin: 4.8%**. 4.8% of revenue is left after running the business, which leaves little cushion in a downturn.
- **Net margin: 4.5%**. 4.5% of each dollar of sales reaches the bottom line.
- **Return on equity: 3.5%**. 3.5% on shareholders' equity is weak; the business earns little on the capital its owners have in it.
- **Return on invested capital: 4.0%**. Return on all capital, debt included, is 4.0%: close to or below the cost of capital, so growth may not create value.
- **Return on assets: 3.5%**. Each dollar of assets produces 3.5% of profit.

## Growth
- **Revenue growth (1 yr): 13.0%** (3-yr -9.5%/yr, 5-yr 3.8%/yr). Revenue grew 13.0% over the last year, against 3.8% a year compounded over five years: growth is accelerating.
- **EPS growth (1 yr): 50.5%** (3-yr -41.7%/yr, 5-yr -5.3%/yr). Earnings per share rose 50.5%, faster than revenue, so margins expanded or the share count shrank.
- **Free-cash-flow growth (3 yr): -8.8%/yr**. Free cash flow has compounded at -8.8% a year over three years, keeping pace with earnings: the growth is real cash.

## Financial health
- **Debt to equity: 0.01**. Debt is 0.01 times equity: a conservative balance sheet.
- **Altman Z-score: 6.70**. A Z-score of 6.70 places the company in the safe zone for bankruptcy risk.

- **From 52-week high: -27.1%** (117.1% above the low). Trading 27% below its 52-week high.
- **200-day average: above**. The price sits above its 200-day moving average, the usual definition of an uptrend.
- **RSI (14-day): 49**. An RSI of 49 is neutral.
- **Beta (1 yr): 2.53** (volatility 67%). Beta of 2.53 against the S&P 500: the shares move much more than the market.
