SJG Sejong makes automotive parts, with metal and structural components — seat frames, fuel tanks and body parts — as its mainstay, supplying carmakers to build a large frame of roughly ₩1.9 trillion in recent annual revenue, while its market cap of ₩150.2 billion is on the small side. In February 2026, annual revenue of ₩1.9 trillion, operating profit of ₩85.4 billion and net profit of ₩68.7 billion were confirmed; in March it resolved a cash-and-in-kind dividend (a dividend yield of about 3.7%), and first-quarter operating profit continued at +63%. What stands out lately is that operating profit is growing quickly and profitability is supported by an ROE of 13.2%, while the price has fallen to 2.2x one year's earnings and 0.3x book value — clearly cheap on both earnings and assets; the flip side is that with a small market cap a single disclosure or one-off factor can swing the metrics sharply, and as an auto-parts name its appeal fades in phases where carmaker volumes slow or the 152.7% debt ratio becomes a burden.

🔎 In-depth analysis
- SJG Sejong makes automotive parts.
- Metal and structural components — seat frames, fuel tanks and body parts — are its mainstay, and it earns revenue by supplying carmakers.
- Recent annual revenue is roughly ₩1.9 trillion; a revenue base this large relative to the company's size means it supplies a great many parts.
- With a market cap of ₩150.2 billion it is on the small side in the market, so it is best to watch not only the flow of the business itself but also the effect each disclosure has on results and the share count.
- The latest close is ₩5,860 and market cap is ₩163.0 billion.
- The price sits below the 20-day line (₩6,272) and below the 60-day line (₩7,269).
- Trading under both its short- and medium-term moving averages, the trend is on the soft side.
- The RSI (a gauge that measures the strength of gains versus losses over the last 14 days on a 0-100 scale) is 38.6, a neutral level.
- The one-month change is -11.5%, the three-month change is -17.8%, and the position versus the 52-week high is -50.5%.
- Relative strength against the KOSPI is 30 (on a 1-99 scale that weights recent index-relative returns more heavily over the past year, with higher meaning stronger than the market).
- That places it in roughly the top 70% of all stocks by strength.
- Over the past three months it lagged the index by 37.2%.
- It is best to read the chart alongside trading volume and disclosure dates.
- Recent annual revenue is ₩1.9 trillion, operating profit is ₩85.4 billion, and net profit is ₩68.7 billion.
- The operating margin is 4.5%, and ROE (a profitability metric showing how much is earned on equity in a year) is 13.2%, above the peer average.
- The debt ratio (debt relative to equity) is 152.7%, an unremarkable level for the auto-parts sector, and the interest coverage ratio of 4.45x means operating profit amply covers interest.
- On valuation, the P/E ratio (how many times one year's earnings the price represents) is 2.37x and the P/B (how many times book value the price represents) is 0.31x.
- A P/B well below 1x means market cap is smaller than the company's net assets, a signal that the price is cheap relative to assets.
- Compared with peers Korea FT (P/E 3.14x), Daechang Forging (5.11x) and Motrex (17.34x), both P/E and P/B are lower, so it sits in undervalued territory whether viewed on earnings or on assets.
- Revenue rose steadily from ₩1.79 trillion in 2023 to ₩1.90 trillion in 2025, and over the same period operating profit grew from ₩51.9 billion to ₩85.4 billion.
- The operating-profit growth rate actually accelerated, from +16.9% in 2024 to +40.9% in 2025, and net profit more than doubled from ₩33.7 billion in 2024 to ₩68.7 billion in 2025.
- When revenue grows in the single digits but earnings jump far more, it means the margin kept on the same revenue is improving.
- This trend continues in the most recent results.
- In the first quarter of 2026, revenue was ₩484.8 billion, up 6.9% from the same period last year, while operating profit was ₩36.2 billion, up 63.3%, and net profit was ₩39.3 billion, up 64.0%.
- With the already-confirmed first-quarter results alone filling a large part of last year's full-year operating profit (₩85.4 billion), it is clear that this year's earnings power sits a step above last year's.
- It is a phase where margin improvement and a steep rise in quarterly earnings appear together, with earnings inflecting upward.
- The disclosure flow is concentrated on results and shareholder returns.
- On February 23, 2026, a profit-structure change disclosure confirmed annual revenue of ₩1.9 trillion, operating profit of ₩85.4 billion and net profit of ₩68.7 billion, in the same direction as the earnings improvement noted above.
- On March 6, 2026, it resolved a cash-and-in-kind dividend to return profit to shareholders, with a dividend yield of about 3.7% — not a small figure.
- There was also a decision on August 8, 2025 to terminate a treasury-share acquisition trust contract; such shareholder-return disclosures are best read alongside whether actual cash flow and earnings power support them.
- This is a stock with relatively distinct strengths.
- Operating profit grew quickly through 2024-2025 and continued at +63% in the first quarter, while the price has fallen to 2.2x one year's earnings and 0.3x book value — clearly cheap on both earnings and assets.
- Profitability is supported by an ROE of 13.2%, and with a roughly 3.7% dividend and treasury-share-related returns added, the low valuation looks less like simple lack of popularity and more like results not yet reflected in the price.
- The point to be careful of is the small-cap nature.
- With a small market cap a single disclosure or one-off factor can swing the metrics sharply, and as an auto-parts name results move with carmaker production volumes and downstream demand.
- The 152.7% debt ratio, while manageable, can become more of a burden in phases where revenue turns down.
- In short, this is a stock whose undervaluation stays alive as long as the earnings growth and margin improvement continue and downstream demand holds; conversely, if carmaker volumes slow or the earnings prove to have leaned on large one-off gains, that appeal fades.
🔎 Valuation vs peers Undervalued
A peer set of auto-parts names close in market cap.
| Peer | P/E | P/B | ROE |
|---|---|---|---|
| Motrex | 17.43x | 0.52x | 2.96% |
| Korea Fuel-Tech | 3.34x | 0.56x | 16.85% |
| Daechang Forging | 5.37x | 0.48x | 8.92% |
Within auto parts, we looked first at a peer set of public-data names close in market cap. The current P/E ratio (how many times one year's earnings the price represents) is 2.37x, and the P/B (how many times book value the price represents) is 0.31x. That said, for smaller-cap names, earnings swings and financing disclosures have a large effect, so we did not draw firm conclusions from metrics based solely on last year's confirmed results. The basis for the outlook box is a DART seasonality approximation.

Price history Close · MA20 · MA60
The latest close is ₩5,860 and the market capitalization is ₩163.0 billion. The price sits below its 20-day moving average (₩6,272) and below its 60-day moving average (₩7,269). It is under both its short- and medium-term moving averages, so the trend looks subdued. The RSI (a supplementary indicator that gauges the strength of gains versus losses over the past 14 days on a 0-100 scale) is 38.6, a neutral level. The one-month change is -11.5%, the three-month change is -17.8%, and the position relative to the 52-week high is -50.5%. Relative strength versus the KOSPI is 31 (on a 1-99 scale, converted from returns against the index over the past year with more weight on recent performance; higher means stronger than the market). It is stronger than roughly 30% of all stocks. Over the past three months it lagged the index by 37.2%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.

Key metrics vs sector median
Valuation
The P/E of 2.37x is below the sector median (7.76x). The P/B of 0.31x is below the sector median (0.56x). Both metrics are low versus peers, so the price is not expensive relative to earnings and assets. That said, this P/E is based on last year's (trailing) results. With recent quarterly earnings up sharply, the trailing P/E can look higher than it really is, so a precise read is best done on this year's expected (forward) earnings.
Enterprise value (EV)
EV = market cap + net debt. It reflects cash and debt, so it captures the real cost of the whole business that market cap alone misses; lower multiples are cheaper relative to earnings or sales.
Profitability & financials
Return on equity (ROE) is 13.2%, above the sector average (7.0%). The operating margin is 4.5%. The debt ratio is 152.7%, so the financial structure is moderate.

📖 Plain-language glossary — expand if you are new to this
- P/E
- How many times a year's net profit the price is worth (lower is cheaper relative to earnings). The P/E here is on trailing (last full-year) results; for companies whose earnings swing fast (memory chips and other cyclicals/high-growth), a forward P/E on this year's expected earnings is more accurate.
- P/B
- Price relative to net assets (equity). Around 1x means it trades near book value; below 1x means below book.
- P/S
- Price relative to a year's revenue — useful for growth companies with thin earnings.
- Net debt / EV
- Net debt = interest-bearing debt − cash. Negative means more cash than debt (net cash). EV (enterprise value) = market cap + net debt, closer to what it would cost to buy the whole business.
- EV/EBIT · EV/EBITDA · EV/Sales
- Enterprise value against operating profit (EBIT), EBITDA, or revenue. Unlike P/E these reflect debt and cash; lower is cheaper relative to earnings power or sales.
- FCF / FCF yield
- Free cash flow = operating cash − capex, the cash actually left over. FCF yield = FCF ÷ market cap; higher means more cash generated per unit of market value.
- Intrinsic value (DCF)
- Future free cash flow (or, for some capex-heavy but profitable names, forecast earnings) discounted to today to estimate per-share value. Because it shifts a lot with the discount-rate and growth assumptions, it is shown as a bear/base/bull range, and the basis and assumptions are disclosed in one line beneath it.
- ROE
- How much profit the company earns in a year on its equity (%). Higher means better returns on capital.
- EPS / BPS
- Earnings per share / net assets (book value) per share.
- Operating / net margin
- Profit left from the core business / final profit after tax and interest, per unit of revenue.
- Debt ratio
- Debt relative to equity (%). Higher means more reliance on borrowing (norms vary by sector).
- Current ratio
- Assets convertible to cash within a year against debt due within a year. Above 100% leaves some short-term headroom.
- Interest coverage
- How many times operating profit covers the interest owed. Below 1x means operating profit alone struggles to cover interest.
- Dividend yield / payout ratio
- The year's dividend as a % of today's price / the share of earnings paid out as dividends.
- Revenue CAGR
- Multi-year growth expressed as a single yearly average (compound annual growth rate).
- RSI (short-term signal)
- Whether recent price action is overheated or beaten down. Above 70 is overbought, below 30 oversold.
- MA20 / MA60 (moving averages)
- The 20- and 60-day average price. Price above them signals a firmer short-term trend.
- vs 52-week high
- How far below the past year's peak the price sits now (%).
