KOSPI Versus KOSDAQ: Venue, Disclosure and Peer Context

First correct the symbol example

A previous draft used 035720.KQ as a KOSDAQ example. That is not a safe example: native code 035720 refers to Kakao, which is associated with the KOSPI market, so attaching a KOSDAQ-style vendor suffix can misroute or fail. The corrected examples here are Samsung Electronics native code 005930 on KOSPI and Kakao Games native code 293490 on KOSDAQ.

Common vendor forms are 005930.KS and 293490.KQ, but KRX and OpenDART records are the identity sources. Provider suffixes remain provider metadata.

1. What the markets describe

KRX describes KOSPI as its main-board market and notes large global corporations such as Samsung Electronics. KRX describes KOSDAQ as a market launched in 1996 to provide capital for startup and small-to-medium companies, with technology, biotechnology, culture, entertainment, software, and games prominent in its history.

These descriptions are context, not a rule that every KOSPI company is mature or every KOSDAQ company is speculative. Listing requirements, liquidity, free float, governance, profitability, and business risk must be checked at issuer level.

2. Build a venue verification record

Use KRX's listed-company search to confirm market, company, native code, shares, and listing status. Then use OpenDART for the exact business report or annual financial filing. Save the receipt number, filing date, reporting period, consolidated or separate statement, units, and language used.

OpenDART's English XBRL viewer warns that taxonomy revisions can make some tables differ from the submitted business report and directs readers to the existing DART viewer for accuracy. That warning belongs in the research record. XBRL is useful for structured extraction, but material conclusions still need the filed report and notes.

3. Venue is not the peer-selection thesis

Samsung Electronics and Kakao Games demonstrate why a cross-market comparison cannot stop at KRX. One has manufacturing assets, device and component segments, inventory cycles, and large capital expenditure. The other depends on game portfolios, launches, user engagement, platform economics, intellectual property, and acquired intangibles. A shared KRW reporting currency does not make their margins or cash reinvestment comparable.

For Samsung, a defensible operating peer set may begin with semiconductor or electronics companies and then reconcile segment mix. For Kakao Games, a defensible set may begin with Korean game publishers and then reconcile platform, geography, development ownership, release slate, and capitalization of development costs. Market venue remains a liquidity and governance field, not the reason for inclusion.

4. Normalize share classes, KRW units, and fiscal periods

Korean issuer names can have ordinary and preferred securities with nearby codes. Verify the intended class before combining price and earnings. Store whether values are KRW, thousands, millions, or billions of KRW; a unit-scale error can be one thousand times larger than an FX error.

Compare exact year-ends and do not rank the two filing examples in the table: they represent different fiscal years and unrelated businesses. A synchronized peer analysis should use filings for the same operating period or clearly reconstruct trailing periods. When translating to another currency, use dated rates and preserve native KRW beside converted values.

5. Disclosure and governance checks

Read related-party transactions, controlling shareholders, treasury shares, share-based compensation, convertible securities, guarantees, and material subsidiaries. Review KRX notices for trading status and corporate actions, and use DART for amendments. A later correction or amended business report should supersede the earlier extracted version in the data pipeline without deleting the audit history.

Translation can obscure legal meaning. Store the Korean document link even when using the English XBRL view, and flag machine-translated interpretations for human review. Do not convert a disclosure label into a U.S. GAAP term merely because the English words appear similar.

6. Korea research checklist

• Verify company name, native six-digit code, KOSPI or KOSDAQ market, and current listing status.
• Map the provider suffix only after the KRX identity is confirmed.
• Confirm ordinary versus preferred share and the exact price currency.
• Save the OpenDART receipt number, filing date, period, units, statement scope, and amendments.
• Build peers from business model, segment mix, customers, capital intensity, and cycle exposure.
• Normalize KRW unit scale and fiscal periods before calculating margins or valuation.
• Inspect related parties, treasury shares, dilution, guarantees, and corporate actions.
• Retain Korean source links and mark translation-dependent judgments for human review.
