Summary

The key reason SK Square’s share price fell from the 2.1 million won range in June to the 1 million won range was the combination of SK Hynix’s decline and a wider holding-company discount. Because investors had effectively gained indirect exposure to a single Hynix stock, along with expectations for shareholder returns, the downside was amplified when those expectations reversed.

What this really means is that SK Square has not escaped its status as an undervalued holding company; it has become a high-volatility semiconductor substitute that had already priced in a narrowing discount.

What Happened

According to Maeil Business Newspaper, SK Square surged from the 300,000-won range early this year to reach the 2.1 million-won range in June, then fell back to the 1 million-won range. Over the same period, it moved almost as one with SK Hynix, which also experienced both sharp gains (surges) and sharp drops (plunges). This was not simply a synchronized decline. It resulted from asset value and the discount rate moving in the same direction.

SK Square is an investment company that owns about 20% of SK Hynix. Net asset value (NAV) is the value of assets after subtracting liabilities, and concentration is exceptionally high: about 98% of SK Square’s NAV is attributable to the value of its Hynix stake. When Hynix’s market capitalization falls, the numerator—NAV—declines; when market sentiment cools, the holding-company discount applied by the market also widens.

The same formula worked in the opposite direction. Daishin Securities raised its July target price for SK Square to 2.1 million won, applying a 30% NAV discount. The valuation simultaneously reflected Hynix’s share-price gains, a premium for its U.S. depositary receipt, and the possibility of higher dividends. The stock quickly priced in all three expectations, then during the correction forced investors to reassess their durability all at once.

Structural Background

Holding-company share prices are not determined solely by the value of their stakes. The discount rate depends on how much of the dividend received from subsidiaries is returned to parent-company shareholders, whether unlisted investment assets are monetized, and whether treasury shares are actually canceled. SK Square has been discussing a 210 billion won treasury-share cancellation and a 200 billion won cash dividend in 2026, giving it potential tools to narrow that gap.

However, even if Hynix’s HBM and server DRAM earnings rise, they do not flow directly into SK Square’s earnings in the same quarter. Hynix must first generate cash, its board must set dividend and treasury-share policies, and SK Square must then return the incoming funds. A time lag and decision-making risk remain between the semiconductor cycle and SK Square’s shareholder returns.

Stock and Industry Impact

  • SK Square faces both a decline in the value of its Hynix stake and an expanded NAV discount. Conversely, if the cancellation and dividend proceed as planned, it will have grounds to defend the discount rate.
  • SK Hynix is the starting point for HBM and server DRAM demand and earnings expectations. If shipment or pricing expectations weaken, the basis for valuing SK Square falls immediately.
  • Samsung Electronics is the comparison company for the memory cycle. Faster expansion of Samsung Electronics’ HBM supply would confirm broader industry demand, but could reduce Hynix’s competitive premium.
  • Holding-company industry sector faces a warning that rising asset values alone do not complete discount elimination. Only companies that connect cash inflows to cancellations can sustain a revaluation.

Bull vs. Bear Scenarios

The bullish path is one in which Hynix sustains shipments and earnings from high-value memory products while expanding dividends. If SK Square channels incoming cash into treasury-share cancellations or cash dividends, rising NAV and a narrower discount could again reinforce each other. That would explain why its share price could show greater elasticity than Hynix’s.

The bearish path is one in which slowing AI investment lowers expectations for Hynix’s earnings or SK Square’s returns fall short of market expectations. If the NAV discount widens again, SK Square’s recovery will be slow even if Hynix’s share price stabilizes. The very speed of its rise from the 300,000-won range early this year to the 2.1 million-won range in June could itself turn into a valuation burden.

Investor Action Points

  • In SK Hynix’s next-quarter earnings, check HBM shipments, server DRAM demand, and memory-price trends.
  • Use filings to verify whether SK Square’s 210 billion won treasury-share cancellation and 200 billion won cash dividend are executed on schedule.
  • Compare SK Square’s market capitalization with the value of its Hynix stake to calculate whether the NAV discount remains around 30%.
  • If only SK Square rises without a rebound in Hynix’s share price, first check whether new grounds for a narrower discount have emerged.
