IR Disclosure Red Flags in Korea: What to Verify in DART Before You Trade

A price move before a Korean company’s IR event is a reason to verify the public record, not proof that anyone traded on inside information. Before acting, build a timestamped source trail: find the IR-event notice, locate any fair or timely disclosure covering the headline, open every attachment, and check for later corrections. If the claim exists only in a presentation, news story, or social post—and the underlying material filing cannot be found—pause the trade.

Use this disclosure ladder

Record	What it establishes	What it does not establish
IR schedule or event notice	When and why the presentation was planned	That every statement in the event was already public
Fair or timely disclosure	The market-wide release of forecasts, provisional results, plans, or a material event	That the first version remains current
Correction or follow-up filing	What changed and when the issuer amended the record	That an earlier price move was unlawful

Verify the timestamps before deciding

Check in this order: search the company in DART’s advanced filing search; compare the filing time with the headline and price move; open the original document and attachments; then search the same subject for “revised” or corrective filings. Use KIND’s IR schedule to confirm the event, but do not treat a calendar entry as the material disclosure itself.

KRX distinguishes timely disclosure, inquiry disclosure, voluntary disclosure, and fair disclosure. Its fair-disclosure rule is designed so important information intended for selected recipients is disclosed to the market first. A later FSC enforcement release may show how authorities handled a completed case; it is not a shortcut for accusing a different company. Missing, conflicting, or corrected documents are a stop signal for further verification—not a buy or sell signal.

If the public trail is complete and you still choose to trade, separate that conclusion from execution: review market-order versus limit-order risk and size the trade through the risk-management decision hub.

Educational use only: this checklist does not determine whether a legal violation occurred and is not a recommendation to trade any company.
