Abstract: We analyzed the earnings revision of MSCI South Korea index constituents for July 2026, with the index declining 24% from 3,228 to 2,462 and the 2026E consensus EPS falling 3.5% month-on-month from 328.1 to 316.8. Individual stock EPS revisions contributed an estimated 6.99 won to the index EPS change, with 45 stocks revised up versus 28 revised down. The largest drags on index EPS came from SK Hynix (000660 KS, impact -11.0 won) and Samsung Electronics (005930 KS, impact -5.2 won), both due to weight drift from sharp price declines of 35.2% and 21.4% respectively. Among individual stock EPS revisions, KAL (003490 KS) led gainers with a 50.8% increase and SK Innovation (096770 KS) rose 47.5%, while LG Display (034220 KS) saw the steepest cut at -68.5% and LG Chem (051910 KS) fell 39.5%.
