임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 95% confidence The document is titled '임원ㆍ주요주주 특정증권등 소유상황보고서' which translates to 'Report on Ownership Status of Certain Securities by Executives and Major Shareholders.' It contains detailed information about securities ownership changes by an individual named 양명훈, including dates, share quantities, and ownership percentages. The document is a formal report submitted to regulatory bodies such as the Securities and Futures Commission and the Korea Exchange. It is not an annual or quarterly financial report, nor is it a general regulatory announcement or a proxy statement. It specifically reports insider share ownership changes, which aligns with the definition of Director's Dealing (DIRS). The document length is 2453 characters, which is consistent with a detailed insider transaction report rather than a full financial report or announcement. Therefore, the correct classification is DIRS with high confidence.

자기주식처분결과보고서
Transaction in Own Shares Classification · 100% confidence The document is titled '자기주식처분결과보고서' which translates to 'Report on Disposal of Treasury Shares'. It details the disposal of treasury shares by SK Hynix, including dates, quantities, prices, and related information. The document is relatively short (2287 characters) and focuses specifically on the results of treasury share disposals. This matches the description of 'Transaction in Own Shares' filings, which report on the company's buying back or selling its own shares. There is no indication that this is an announcement of a report or a certification, nor does it contain comprehensive financial statements or other report types. Therefore, the correct classification is POS (Transaction in Own Shares).

This matches the definition of a Major Shareholding Notification, which involves reporting changes in significant share ownership levels. The document length is 2451 characters, which is consistent with a detailed notification rather than a full financial report or announcement. Therefore, the appropriate classification is Major Shareholding Notification (MRQ).
