Major indices

  • KOSPI 5,554.22 -7.57%
  • KOSDAQ 760.82 -7.65%

Today was less about which industry fell than about the whole market being emptied at once. The KOSPI closed 7.57% lower at 5,554.22 and the KOSDAQ 7.65% lower at 760.82, with sell-side sidecars and circuit breakers triggered in both markets; only 91 KOSPI and 197 KOSDAQ names advanced, against 812 and 1,495 decliners respectively. Just 4 stocks set 252-session highs while 56 set new lows, so the floor gave way at the single-stock level as well, not only in the indices.

What held up was domestic consumption and pharmaceuticals, the demand that does not track the cycle; what gave way was the whole set of growth and heavy-industry sectors that had carried the market this year. Not one of the 43 semiconductor names we track closed higher, with power grid, robotics, hydrogen and EV batteries following, and consumer staples was the only industry with a positive average move. Even so, Samsung Biologics, Yuhan and BGF Retail rose. The industry and stock-level moves are laid out under 'Industry movers' below.

The move to cut risk was not confined to equities. The three-year government bond yield fell 1.6bp to 3.867% and the ten-year 6.8bp to 4.193% as demand flowed into bonds, while gold rose 0.43% to 4,144.22 dollars an ounce and silver fell 2.3%, concentrating the safe-haven bid in gold. The won closed at 1,338.6 per dollar, 1.9 won stronger than the previous day, barely moving relative to the slide in equities. As of October 13 investor deposits stood at 100.0983 trillion won, down 340.6 billion won from the prior observation, and credit-financed trading at 34.2529 trillion won; on the same day forced liquidations rose by 32.3 billion won to 59.3 billion won and their share climbed to 5.6%, a sign that leveraged positions are starting to be sold out involuntarily. KOSPI non-arbitrage program flows were net sellers of 143.8 billion won, taking the five-session total to 4.5325 trillion won of net selling.

The trigger was pulled in the United States. September consumer price inflation came in above expectations, reviving talk of a further Federal Reserve rate increase (Digital Daily), and together with the dispute over the profitability of AI investment it pushed US technology shares lower overnight; in Korea that arrived today as a slide in the large semiconductor names led by Samsung Electronics and SK hynix. Foreign investors sold more than 3 trillion won net on the main board, an eighth consecutive session of selling (Herald Business), and in power equipment a run of target-price cuts made the falls at Sanil Electric and Hyosung Heavy Industries especially steep (Seoul Finance). Korea's weight in the emerging-market index stood at 19.08% on October 13, down 2.17 percentage points in a week, widening the gap with Taiwan, which held at 29.41%. On relative strength semiconductors remain the leading industry, yet by today's move they fell the most, and Doosan Tesna, the leading individual name, fell 4.44%. What actually rose on the day was KODEX Consumer Staples, up 1.73%.

The index closes, percentage moves and the circuit-breaker halts are facts confirmed in closing reports from several outlets, while the advance-decline counts and the industry and single-stock moves are figures this site compiles itself. The account that US inflation and the AI profitability dispute lie behind the fall comes from brokerage commentary relayed by the press, so how much of a 7% decline it explains remains unclear. Investor deposits, credit-financed trading, forced liquidations and the emerging-market weights are as of October 13, and crude prices as of October 6. The won figure is compiled on a different basis and may differ from the move reported in foreign-exchange closing coverage.
