KOSPI and KOSDAQ Both Hit Record Highs; Buffett Indicator Debate Resurfaces
The KOSPI rose as much as 2.2% intraday to a fresh record of 6,622 points, pushing Korea's total market capitalization above 6,000 trillion won for the first time. The KOSDAQ likewise climbed past 1,124 points, breaking through a previous high it had struggled to clear for some time. Foreign investors were net buyers of about 460 billion won and institutions bought more than 1 trillion won, with financial investment firms and pension funds among the institutional buyers, forming a broadly favorable supply-demand backdrop. On the KOSDAQ, institutions also turned net buyers, supporting the rally.
Despite the broad advance, the picture at the individual stock level was mixed. On the KOSPI, 500 stocks rose while 360 fell; on the KOSDAQ, 940 rose while 650 fell — a meaningful share of decliners even amid a record-setting session. Investors holding stocks that rose less than the index, or fell outright, could feel a sense of relative deprivation despite the overall market strength.
With the KOSPI eyeing 7,000, the Buffett Indicator — market capitalization relative to GDP — returned to the spotlight. Under Warren Buffett's framework, a ratio above 200% of GDP is generally read as a sign of overvaluation; with Korea's GDP at roughly 2,500 trillion won, the current market cap already exceeds twice that level, putting the market above that threshold. Still, some argued the comparison oversimplifies matters, since GDP is a backward-looking stock measure while listed companies' earnings — a flow measure — are running nearly double last year's levels. Because GDP tends to lag, whether the market's advance constitutes a bubble will hinge on whether future GDP and corporate earnings growth catch up, and a recent GDP reading that came in roughly double consensus was cited as an encouraging sign.
Against this backdrop, Hyundai Department Store jumped 15.8% to a fresh high, while traditional domestic-demand names Hanwha Galleria and Lotte Shopping, along with food and beverage stocks, also advanced. Since a genuine economic upturn requires both exports and domestic demand to improve together, the day's strength in retail names was seen as a meaningful signal.
