SK hynix Sold ADRs High, Then Bought 40 Trillion Won of Its Own Stock Low

SK hynix plans to buy 24.07 million of its own common shares on the open market and cancel all of them, at a planned cost of 40.0043 trillion won, or about $27 billion, the largest such program in the history of the Korean stock market ^[1]. It committed to that roughly a month after raising more than $2.6 billion by issuing American depositary receipts to U.S. investors at a price about 50% higher than the current level ^[2].

The arithmetic is the point. The planned outlay implies roughly 1.66 million won per share ^[16]. Repurchasing at a level 50% below the issue price means retiring stock at about two thirds of what the ADR buyers paid a month earlier, a discount near 33% ^[3], and spending roughly ten times the ADR proceeds to do it ^[17]. The Wall Street Journal, which flagged the sequence on the 20th, first called the decision a "head-scratcher," noting the shares were still up about 470% from a year earlier despite a recent correction ^[4]. It then landed on the timing, calling the sequence "in contrast to the past behavior of U.S. companies" and consistent with selling high and buying back lower ^[5].

That contrast is the useful part for anyone allocating capital in a cyclical business. According to the Journal, in the quarter the dot-com market peaked, buybacks by S&P 500 companies hit a record, yet the real buyback yield, measured against index market capitalisation, was only 1.2% ^[6]. Three years later, with prices lower, the dollar value of buybacks had shrunk about 40% while that yield rose by roughly a third ^[7], to something close to 1.6% ^[18]. The 2007 to 2009 sequence rhymed: record buybacks at the 2007 peak, then an 85% collapse by the spring of 2009, after prices had fallen ^[8]. Executives who know their own businesses best, the paper noted, tend to be aggressive buyers when the stock is expensive and passive when it is cheap ^[9]. It also recalled Warren Buffett's criticism of the blanket claim that buybacks harm shareholders, alongside Berkshire Hathaway's own decision to halt repurchases for nearly two years while accumulating cash ^[10].

The sell side is treating the program as a floor rather than a valuation event. Barclays keeps an overweight rating and a $300 target on the ADRs, calling the stock undervalued at about 3.8 times expected earnings this year ^[11]. Nomura stayed positive on high-bandwidth memory share and AI-driven profit growth ^[12]. Citigroup's Peter Lee said the buyback could act as a meaningful near-term floor and support the downside ^[13]. CLSA's Sanjeev Rana said the 40 trillion won meets investor expectations and raised the prospect of further buybacks or a special dividend later ^[14]. JP Morgan counted 39.4 million shares pledged for cancellation over the past eight months, including this 24.07 million ^[15], which implies about 15.33 million shares committed in earlier tranches ^[19]. Some investors read the size as confidence in cash generation rather than share-price defence ^[20].

What to watch: whether the shares are actually acquired and cancelled near the planned 40.0043 trillion won cost ^[1], or whether the average price paid drifts up as the stock recovers; whether the follow-on returns Rana floated arrive ^[14]; and whether SK hynix repeats the equity-issuance-then-repurchase sequence at the next cycle peak, which is where the discipline would be tested rather than demonstrated ^[2].
