Shares of SK Square, the South Korean tech holding company that controls a major stake in chipmaker SK hynix, tumbled 7.6% to ₩1,257,000 on June 5 as the stock's dividend payout date collided with a broader retreat in global semiconductor names, raising questions about whether the dip is a routine post-dividend adjustment or something more lasting. SK Square Sheds 7.6% on Dividend Payout Day — Is This a Predictable Reset or a Warning About the AI Chip Rally's Limits?
Shares of SK Square, the South Korean holding company whose crown jewel is a 20% stake in memory-chip giant SK hynix, slid 7.6% to ₩1,257,000 on June 5 — the day it pays its dividend — as two forces collided: a routine post-dividend adjustment and a global semiconductor rout triggered by softening AI-chip expectations.
The Dividend Math Explains Some, but Not All, of the Drop. SK Square's dividend of ₩1,550 per share was paid June 5, with an ex-dividend date of May 14. That tiny payout — yielding just 0.13% — cannot mechanically account for an 8% decline. The stock rallied from ₩1,233,000 on May 29 to ₩1,361,000 by June 4, suggesting traders bought ahead of the payout and are now unwinding those positions. Investors who entered purely for the dividend are locking in gains, amplifying selling pressure beyond the modest cash distribution.
A Global Chip Selloff Is Hitting SK Square Through Its Biggest Asset. Broadcom projected third-quarter AI chip sales of $16 billion, below analysts' estimates of $17.2 billion, and did not raise its 2026 AI semiconductor forecast.
The weakness spread industry-wide, with Broadcom plunging 15%, AMD falling ~6%, and the iShares Semiconductor ETF declining around 5%. SK hynix, which carries a market cap of $1.064 trillion and fell roughly 2.9% on June 4 , is SK Square's primary source of value. Any doubt about AI spending growth directly erodes the thesis for owning SK Square.
The Buyback Program Provides a Floor — But a Thin One. SK Square is currently executing a ₩40 billion share buyback running through June 25, 2026, and has cumulatively returned ₩710 billion through buybacks. That support is real but modest relative to the company's ₩162 trillion market cap . Meanwhile, last quarter's net income surged to ₩8.38 trillion from ₩3.28 trillion , driven overwhelmingly by SK hynix's AI-memory boom — making the holding company's fortunes almost entirely dependent on one bet.
The Bigger Question: Can a Holding-Company Discount Narrow During a Chip Downturn? SK Square essentially offers a discounted way to own SK hynix. But growing investor anxiety that AI infrastructure spending expectations may have become overly optimistic means that discount could widen, not shrink, if the semiconductor pullback deepens. With a beta of 1.96 — meaning the stock moves nearly twice as much as the broader market — shareholders should expect amplified volatility in both directions.
