Shinwon Construction Company (SHINWON CONSTRUCTION CO., LTD.; Korean name 신원종합개발) is a residential-building construction company listed on South Korea’s KOSDAQ market under ticker 017000. A useful reading of its share price always ties the number to the session date, currency, data source, and whether the series is raw or adjusted. NICE CompanySearch’s 16 October 2026 snapshot shows a close of KRW 2,175, up KRW 25 for that reference session. That figure is not interchangeable with every quote on the internet: StockAnalysis, using S&P Global Market Intelligence data, records a KRW 2,320 close for 23 September 2026. The dates are different, so the prices can both be correct.
Identify the security before reading a number
The first check is the issuer and market, not the price. Shinwon Construction is the listed company name; its Korean name is 신원종합개발. The market is KOSDAQ, South Korea’s exchange segment for this listing, and the local ticker is 017000. Prices are quoted in South Korean won (KRW), and the ticker should be entered exactly as 017000 in a Korean-market data service.
A ticker is an identifier, not a forecast. It tells you which security a row belongs to, while the row’s date and session tell you when the trade data were recorded. A headline that says “017000 is at KRW 2,175” is incomplete unless it also states the as-of date and whether the value is a live, delayed, or historical close.

How a daily price table works
Daily history normally uses OHLCV columns. Read each field as a measurement of one exchange session:

| Field | Meaning | How to use it |
|---|---|---|
| Open | The first traded price shown for the session | Compare it with the prior close to see whether the session began with a gap. |
| High | The highest traded price in the session | Use it with the low to measure the day’s traded range. |
| Low | The lowest traded price in the session | It is a traded extreme, not necessarily a price available for every order. |
| Close | The final traded price in that daily record | Use it for close-to-close changes, provided the prior reference close is known. |
| Change percentage | The close compared with the prior reference close | Calculate as (current close − prior close) ÷ prior close × 100. |
| Volume | Number of shares traded during the session | Compare with the stock’s own normal activity rather than with a large-cap benchmark. |
StockAnalysis also supplies an adjusted close. An adjusted series changes historical prices for events such as stock splits so that a chart’s past returns remain comparable. A raw close is the price actually reported for that session; an adjusted close is a calculation intended for continuous analysis. Before comparing two charts, confirm which one you are viewing. Do not combine a raw current close with an adjusted historical close in a return calculation.
A dated example
StockAnalysis’ 23 September 2026 history row gives the following OHLCV record for 017000:
| Date | Open (KRW) | High (KRW) | Low (KRW) | Close (KRW) | Volume (shares) |
|---|---|---|---|---|---|
| 23 September 2026 | 2,330 | 2,355 | 2,295 | 2,320 | 17,462 |
The high-minus-low range was KRW 60. The close was KRW 10 below the open, a decline of about 0.43% from that session’s opening trade (10 ÷ 2,330). Those are intraday calculations; they do not substitute for a close-to-close percentage, because the prior session’s reference close is not included in this row.
Why two websites can show different prices
The most important cross-check is the as-of date. NICE CompanySearch’s issuer snapshot dated 16 October 2026 reports a KRW 2,175 close and a KRW 25 increase. The StockAnalysis row dated 23 September 2026 reports KRW 2,320. A market price can move between those sessions, so the discrepancy does not by itself indicate an error.
Other differences are common even when two services appear to cover the same date. Work through these checks before drawing a conclusion:

- Same session: Confirm that both rows refer to the same Korean trading date, not your local calendar date.
- Same field: Compare close with close. A page may display a current quote, an intraday last trade, an official close, or an adjusted close.
- Raw versus adjusted: A split-adjusted chart can show a different historical value from an unadjusted exchange record.
- Delayed display: Exchange and vendor pages may show delayed data. Record the delay status and retrieval time.
- Currency: Keep the unit in KRW. A converted display in another currency introduces an exchange-rate timestamp in addition to the stock-session timestamp.
- Corporate-action handling: Check whether a provider restated earlier rows after a split or other adjustment.
Preserve the retrieval timestamp with any screenshot or exported file. Prices and market status can change while a page is open, and a later review should be able to reproduce what you saw.
How to read volume for 017000
Volume is a count of shares traded in one session. It is not the number of shareholders, the company’s shares outstanding, or the won value exchanged. For a small or thinly traded KOSDAQ issue, the stock’s own baseline matters most.
Investing.com displays an average daily volume of 17,773 shares for its stated historical-data period. StockAnalysis history illustrates the dispersion around that average: volume was 3,135 shares on 17 September 2026 and 249,250 shares on 13 August 2026. The 13 August count was roughly 14 times 17,773, while the 17 September count was about 18% of that baseline. The 23 September row recorded 17,462 shares, close to the displayed average.
| Observation | Volume | Relative reading against 17,773-share average |
|---|---|---|
| 13 August 2026 | 249,250 shares | About 14.0 times the average; an unusually busy session. |
| 23 September 2026 | 17,462 shares | Approximately the average; not, by itself, an exceptional volume signal. |
| 17 September 2026 | 3,135 shares | About 0.18 times the average; a very quiet session. |
Combine volume with the price move
A rising close accompanied by unusually high volume suggests more participation than the same percentage move on very low volume. A falling close on high volume can likewise indicate that many more shares changed hands during the decline. This is an interpretive heuristic, not proof of the cause of the move or of future returns.
Use at least three comparisons: the day’s volume against a rolling average, the close against the prior close, and the day’s range against recent ranges. A large share count at a low price can represent less transaction value than a smaller share count at a high price, so check transaction value when the exchange or data provider supplies it. Shares traded alone can mislead when prices differ materially.

Get an authoritative history from KRX
The Korea Exchange (KRX) Data Marketplace is the preferred verification point for Korean-listed data. Its KOSDAQ market displays include individual-security price history, investor trading, volume, and transaction-value datasets. Some market displays are 20 minutes delayed, so a displayed quote is not automatically a real-time execution price.
Free tools Windows power users keep installed
One-click scans. No signup required.
- Open the KRX Data Marketplace and choose the KOSDAQ individual-security price-history area. Use the exchange’s market-data navigation rather than a generic web search result.
- Enter 017000. Verify that the returned issuer is Shinwon Construction (신원종합개발), not a similarly numbered instrument.
- Set the exact date interval and frequency. For a daily chart, specify the Korean session dates you want. Do not rely on a browser’s automatically converted date.
- Export or record the OHLCV fields. Keep open, high, low, close, volume, and transaction value when available; note any separate adjusted-close field.
- Write down the units and timing. Record KRW, the exchange session date, the page’s delay status, and your retrieval timestamp.
- Cross-check the change. Recalculate the close-to-close percentage from the current and prior reference closes instead of assuming a provider’s “change” column uses the same convention.
- Review disclosures before assigning a cause. Use KRX-linked issuer-disclosure channels to check whether a filing or corporate action coincided with the move.
This workflow produces a reproducible record. A third-party table can still be useful for screening, but retain its provider name, as-of date, and adjustment note beside every copied figure.
A consistent comparison method
When comparing two dates, two websites, or two chart settings, use the same sequence each time:
- Align the session. Match the Korean trading date and confirm that neither row is an intraday quote from a different time.
- Align the price treatment. Choose raw close for reporting the historical trade record, or adjusted close for a split-consistent return series. Label the choice.
- Measure both absolute and percentage change. The won difference shows the cash movement per share; the percentage normalizes it by the starting price.
- Measure the intraday range. Subtract low from high, and compare that range with recent sessions.
- Normalize volume. Divide the session’s shares by a stated rolling average or by the 17,773-share average displayed for the Investing.com period. State which baseline you used.
- Check liquidity in value terms. Transaction value can reveal whether a large share count actually represented substantial trading activity.
- Document delay and source. A delayed exchange display and an end-of-day vendor file are different observations even when their dates match.
KOSDAQ rules that change how a move looks
KRX states that KOSDAQ quote increments vary from KRW 1 to KRW 100 according to the share-price level. The minimum visible step on a quote screen is therefore not constant across all prices. A one-tick change at one level cannot be compared mechanically with a one-tick change at another level.
KRX also describes daily price-fluctuation limits that are usually plus or minus 15% from the previous close, together with volatility-interruption cooling periods. A sharp displayed move can therefore be approaching a limit or followed by a pause rather than representing a continuously traded path from one price to the next. When a chart shows a sudden straight-line move, inspect the session status and interruption notices before interpreting it as uninterrupted demand or supply.

Current context for a 017000 chart
NICE CompanySearch’s 16 October 2026 snapshot supplies the following context. These figures describe that snapshot; they are not a valuation conclusion and should not be carried forward without a new date.
| Metric | Value | How to treat it |
|---|---|---|
| Close | KRW 2,175 | Issuer-snapshot close for 16 October 2026. |
| Change | +KRW 25 | Change reported by NICE for that snapshot. |
| 52-week high | KRW 4,470 | Historical reference, not a target price. |
| 52-week low | KRW 1,975 | Historical reference, not a support guarantee. |
| Market capitalization | KRW 25.4 billion | Snapshot value that moves with price and share-count changes. |
| Common shares | 11,668,027 | Reported share count for the snapshot. |
| Foreign ownership | 3.81% | Ownership statistic, not a forecast of foreign buying or selling. |
| PER | 5.67 | Earnings multiple shown by NICE; the period and methodology belong to the provider. |
| PBR | 0.31 | Book-value multiple shown by NICE; not a standalone valuation verdict. |
| EPS | KRW 494 | Earnings-per-share figure in the snapshot. |
| BPS | KRW 9,170.16 | Book value per share in the snapshot. |
Use these numbers to describe the market context around a chart, not to infer that the shares are cheap, expensive, safe, or likely to rise. Multiples depend on the provider’s accounting period, the price date, and whether earnings or book value have changed since the snapshot.

Start with the price path
Look at the sequence of closes first, then inspect each day’s high-low range. A close near the high can indicate that the session finished near its upper traded area; a close near the low indicates the opposite. Neither pattern proves what will happen next, especially in a thin market.
Separate gap, range, and close-to-close moves
For the 23 September example, the open was KRW 2,330 and the prior close is not supplied in the row. You can therefore calculate the open-to-close move (−KRW 10, about −0.43%) and the intraday range (KRW 60), but not a valid close-to-close percentage without the prior session’s reference close. Keeping those calculations separate prevents a common chart-reading error.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteUse volume as confirmation, not a verdict
Mark sessions that are several times the chosen baseline, then ask what the price did on those sessions and whether a disclosure or exchange notice explains the activity. A volume spike with a flat close can represent heavy two-sided trading; a spike with a large move can represent concentrated directional trading. The bar itself cannot identify the participants or the reason.

Troubleshoot common data problems
“The quote is different from yesterday.”
Check whether one page is showing today’s delayed last trade while the other shows the previous official close. Compare the timestamp and label before comparing the number.
“The historical chart does not match the downloadable table.”
Look for an adjusted-close toggle. Charts often default to adjusted data for continuity, while tables may show raw closes. Select the same treatment on both views and check for split adjustments.
“Volume looks implausibly large or small.”
Confirm that the unit is shares rather than lots or transaction value, and that the date is a full Korean session rather than a partial, delayed display. Compare the row with the 17,773-share displayed average and with neighboring sessions.

Verify which reference close the provider uses, whether it rounds before calculating, and whether the displayed price is adjusted. Recalculate from unrounded raw closes when possible, then retain the provider’s stated figure separately.
“The chart shows a sudden jump and then no trades.”
Check KOSDAQ price limits and volatility-interruption cooling periods. A pause or limit condition changes the path by which trades can occur and should be recorded beside the chart.
What the numbers cannot establish
Price, volume, and valuation fields describe market observations; they do not identify a cause. A high-volume rise could coincide with a disclosure, a change in ownership, short-term positioning, or unrelated order-flow effects. Check issuer disclosures through KRX-linked channels before attributing the move to news.
Likewise, the 52-week range, PER, PBR, EPS, BPS, market capitalization, and foreign-ownership percentage are context fields from a dated snapshot. They are not a recommendation, a fair-value estimate, or evidence of future performance. The available tables contain no attributable person-level quotation that adds a verifiable explanation, so the most defensible account stays with the dated measurements and exchange rules.
A recordkeeping template for future checks
For each observation, save a row containing:
- Issuer: Shinwon Construction Company (신원종합개발), ticker 017000, KOSDAQ.
- Session date in the Korean market calendar and your retrieval timestamp.
- Source and whether the display is delayed.
- Currency (KRW), raw or adjusted close, and any corporate-action note.
- Open, high, low, close, close-to-close change, and volume.
- Rolling-volume baseline and transaction value, if available.
- Relevant KRX or issuer-disclosure reference checked before assigning a cause.
Keeping those fields together makes a later comparison meaningful: you can tell whether a difference came from the market, the date, the price adjustment, the unit, or the data feed rather than treating every mismatch as a bad quote.
