Woofun AI reports that SK Hynix will enable two-way conversion between its American Depositary Receipts and Korean common stock starting July 29. While the Korea Securities Depository confirmed the mechanism, practical arbitrage faces significant hurdles for individual investors. Converting Korean shares to ADRs is restricted by the issuer's outstanding issuance limit, meaning available capacity depends on existing ADR volumes. Conversely, converting ADRs back to local shares has no specific cap.

Industry observers note that the process requires separate brokerage applications and foreign exchange procedures, varying by firm. Unlike standard equity trading, conversions cannot be executed instantly via mobile or online platforms, limiting the strategy's viability for retail participants seeking rapid price alignment.
