The Secret of SK Hynix Hitting the Daily Limit Up… The Shocking Structure of How Foreign Investors Profit / Why Leverage Regulation Only Begins Now? | Oh Hyun-jin, Team Leader

Summary

Oh Hyun-jin Team Leader analyzes the record 17.91% KOSPI surge, explaining how foreign hedge funds exploited leveraged ETFs to accelerate declines, and how short-covering and mechanical buying fueled the rebound. He then provides tactical sector ideas: overweight Samsung and SK hynix within semiconductors while trimming other S7 names; buy semiconductor equipment and construction stocks on the Gwangju cluster catalyst; accumulate undervalued securities stocks; watch LG Corp and Doosan Tesna for AI and foundry tailwinds; and reduce bank and insurance exposure as market normalization favors cyclicals over defensives.

• Leverage regulation started today, offering some relief after the crash, but the damage was already done.
• Foreigners systematically exploited inverse leveraged ETFs and short-selling, creating a self-reinforcing selloff that was then reversed by short-covering.
• The semiconductor rebound was triggered by Amazon/Meta/Microsoft confirming AI datacenter capex and seeing sustained cloud demand.
• Investors should focus semiconductor exposure on Samsung Electronics and SK hynix, while reducing other S7 members as the bounce continues with heavy resistance.
• Semiconductor equipment (Tes, Wonik IPS, Eugene Tech) and construction (Daewoo, Hyundai, DL, Samsung E&A) are direct plays on the nearly finalized Gwangju semiconductor cluster.
• Korean securities stocks at 5–6x PER offer a cheap rebound play; conversely, bank and insurance defensives are likely to lag as the market normalizes.
• LG Corp may deserve a re-rating if its Exaone AI model gains recognition; Doosan Tesna is positioned for Samsung foundry recovery.
• Gwangju Shinsegae reflected local cluster expectations, rising 6% in Nextrade, highlighting a niche beneficiary.
