Multiple corroborating sources support the claim. The odaily article '506941' directly matches the claim's core assertions: after the ADR quiet period ended August 4, the market shifted to speculation about a stock split and improved dividends, with no official announcement yet, driven by the reopened disclosure window and the high 166.8 million won share price. Yahoo Finance ('SK Hynix Climbs as Investors Bet on Shareholder Return Plan') independently confirms the 7.9% share surge on shareholder-return expectations after the quiet period ended, and that no formal announcement had been made. BlockBeats, and the earlier odaily/PANews flashes, corroborate the July 10 ADR listing, the ~25-day SEC quiet period ending August 4, and market anticipation of buybacks/dividends. The one nuance is that primary analyst commentary emphasizes buybacks/special dividends more than stock splits, but the split-and-dividend discussion is explicitly documented in odaily '506941'. Overall the claim accurately reflects reported market sentiment.
