Summary

After two days of circuit breakers, KOSPI surged 18% and SK Hynix hit the daily limit. CEO Kim Dong-yeop attributes the bounce to strong US big tech earnings, a short squeeze, and a hedge fund liquidation averted, but warns the move is a reaction to abnormal selling rather than a trend reversal. He expects KOSPI to trade in a range and favors oversold semiconductors, data center infrastructure, secondary batteries, and shipbuilding, while suggesting heatwave stocks as a light touch.

  • KOSPI soared ~18% and KOSDAQ 11.6%, with SK Hynix hitting the upper limit after two consecutive days of historic crashes.
  • The rebound was fuelled by strong US cloud earnings, a short squeeze, and the avoidance of a large hedge fund forced liquidation.
  • CEO Kim Dong-yeop views the rally as a correction of abnormal flows, not a sustainable trend, and sees KOSPI floor near 5,262 with resistance around 7,000.
  • He is bullish on oversold semiconductor and equipment stocks, expecting their rebound to continue next week.
  • Data center infrastructure plays (construction, emergency power) are highlighted due to Korea's AI data center expansion.
  • Secondary battery sector shows early signs of bottoming, aided by quarterly profit recovery and supportive oil prices.
  • Shipbuilding stocks, including engine and equipment names, benefit from US desire to source outside China and strong earnings.
  • Heatwave theme stocks are mentioned only as a light, short-term tactical trade with no long-term conviction.
Ideas
Kim Dong-yeop CEO, Decenter 14:56
KOSPI range-bound between 5,200 and 7,000.
The intraday low of 5,262 on KOSPI is likely a near-term floor that will be hard to break. However, the rally is driven by short squeezes and abnormal factors, not a fundamental trend change. The index will likely trade in a box range roughly between 6,000-6,500, with upside capped around 7,000, and a sustainable breakout above 7,000 is unlikely for now.
Kim Dong-yeop CEO, Decenter 18:23
Oversold Korean semis and equipment will rebound.
The crash was an abnormal sell-off driven by forced liquidations, and US big tech earnings (Amazon, Microsoft, Google) showed strong cloud revenue growth, while AI capex guidance remains robust. The consensus was wrong to call SK Hynix results an earnings shock; the company is actually performing well. Oversold semiconductor and semiconductor equipment stocks will continue their rebound into next week, led by SK Hynix and Samsung Electronics, with substrate and other materials/equipment names also participating.
Kim Dong-yeop CEO, Decenter 19:43
Data center infrastructure stocks set to rise.
AI data center build-out is a structural theme; Korea plans 18 GW of data center capacity by 2035-2040. This will create persistent infrastructure bottlenecks in power, water, and transmission. Construction stocks and emergency power generation companies that supply data centers should benefit from this expansion and the resulting chip and power shortages.
Kim Dong-yeop CEO, Decenter 20:52
Secondary battery sector is bottoming out.
The three major battery makers swung to a quarterly operating profit for the first time in several quarters. High oil prices are reducing the EV affordability problem, helping demand. The sector is quietly bottoming out, presenting a recovery trade in secondary battery materials stocks.
Kim Dong-yeop CEO, Decenter 21:24
Korean shipbuilding to prosper on US needs.
The US will not use Chinese ships for commercial or military purposes, and Korea has a strong position in the global shipbuilding market. Korean shipbuilders just reported massive earnings improvements. Shipbuilding stocks, including engine and equipment makers, remain attractive and should capture a significant share of the potential 100 trillion won US shipbuilding market.
Kim Dong-yeop CEO, Decenter 22:45
Heatwave theme stocks offer short-term bounce.
Heatwave stocks can offer a short-term bounce after a 2-3 day correction when hot weather persists, but they melt away as soon as temperatures drop. This is a light, tactical trade, not a high-conviction position.
