Korea Pension Fund Buys ₩1.8 Trillion in Samsung and SK Hynix Shares to Cushion Intel-Shock Semiconductor Selloff

The Quick Take

• South Korea's pension fund bought ₩1.8 trillion worth of Samsung Electronics and SK Hynix shares over two days to stabilise the market against the Intel earnings shock.
• Samsung Electronics fell 2.84% and SK Hynix dropped 3.87% in pre-market trading after the Philadelphia Semiconductor Index plunged 3.37% overnight.
• The Kospi rebounded 2.24% on institutional buying strength, with the pension fund's record near-₩900 billion single-day purchase anchoring market sentiment.

South Korea's national pension fund stepped in as a circuit-breaker following the Intel earnings shock that caused the Philadelphia Semiconductor Index to crash 7.20% in a single session. The fund's near-₩900 billion net purchase on a single day — ranking among the largest single-day net buys in the fund's history — combined with SK Hynix's own share buyback program of approximately ₩20 trillion, provided the institutional demand shock absorber that prevented the Kospi from following the US semiconductor selloff into deep correction territory. The Kospi closed up 2.24% despite the external semiconductor index rout.

The event illustrates a structural feature of Korean equity markets: the national pension fund (NPS) and corporate buybacks from semiconductor majors routinely serve as the market stabilisation mechanism during external shock events. For international investors monitoring Samsung Electronics and SK Hynix — which together represent approximately 25-30% of Kospi market capitalisation — the government-backed institutional demand acts as an effective put on the semiconductor sector. AMD and Micron, the US peers that also fell 7-8% during the same session, lack a comparable state backstop mechanism.

Market participants should watch whether the institutional buying continues over the following sessions or whether it was a one-time shock response — sustained buying would signal the NPS views current semiconductor valuations as fundamentally undervalued. The macro variable determining the thesis is the trajectory of DRAM and NAND demand recovery, particularly HBM memory demand from AI accelerator programs at NVIDIA and AMD, which is the primary revenue driver for SK Hynix's high-value product line. Any supply-side commentary from Samsung or SK Hynix management at upcoming investor events will be particularly significant.
