KOSPI forward P/E sinks to 5.78x, below 2008 crisis trough
South Korea's KOSPI index has fallen into its cheapest valuation in more than two decades, with a forward price-to-earnings ratio that now undershoots even the depths of the 2008 global financial crisis.
The KOSPI index tumbled 8.8% this week, pushing its 12-month forward P/E to 5.78 times — the lowest since 2004 and below the 2008 crisis trough.
"The current valuation already reflects a severe earnings recession scenario, and even under the most adverse assumptions, the risk-reward profile has turned positive," Goldman Sachs strategists led by Timothy Moe said in a July 17 report.
The index has now fallen roughly 25% from its June 22 peak, with technology, construction and retail stocks leading the decline. The KOSPI's forward price-to-book ratio has retreated to 1.43 times from its June peak, while forward return on equity remains elevated at about 25% — a divergence Goldman described as "rare." Excluding Samsung Electronics Co. and SK Hynix Inc., the broader market trades at 8.79 times forward earnings, still below its historical average, according to UBS.
The valuation collapse reflects a convergence of global semiconductor selling and a momentum reversal that has swept through Korean equities. But with foreign investors turning net buyers this week for the first time in recent weeks, and the government moving to curb speculative leveraged ETF trading, the market may be approaching an inflection point. Goldman maintained its 12-month KOSPI target of 12,000 points, while UBS kept its 9,200 target but shifted to a barbell strategy favoring defensive and value names.
Goldman's stress test showed that even if KOSPI earnings per share were slashed 41% — matching the worst-case decline during the 2008 financial crisis — and applying the crisis-era valuation multiple of 13 times, the index would still sit at about 8,965 points, well above current levels. The analysis underscores how deeply the selloff has overshot fundamental deterioration.
Foreign Flows Turn Positive, But Structure Remains Fragile
Foreign investors recorded net buying of about 190 billion won ($136 million) in KOSPI this week, Goldman data showed, with inflows concentrated in auto (196 billion won) and retail (118 billion won) sectors. Technology stocks, however, saw net selling of 766 billion won, highlighting persistent divergence. The Korean won strengthened 1.2% against the U.S. dollar and 1.5% against the yen this week.
Despite the weekly inflow, year-to-date foreign net selling in KOSPI stands at about 16.1 trillion won, underscoring the scale of the broader exodus. Goldman's Korea equity risk barometer reads minus 2.7, still deep in risk-off territory. Retail investors bought a net 953 billion won this week, while institutions sold 1.19 trillion won.
Leveraged ETF Crackdown Accelerates Deleveraging
South Korea's Financial Services Commission announced a temporary halt on new listings of single-stock leveraged exchange-traded products, effective immediately, alongside a sharp increase in the minimum cash margin requirement to 30 million won ($20,300) from about 3 million won, set to take effect Aug. 5. The regulator also banned marketing of existing products and plans to raise the minimum trading unit to 20 from one in November.
The measures target a market segment that had surged in popularity around Samsung Electronics and SK Hynix before the selloff. UBS analysts said the 30 million won cash requirement — equivalent to about 27% of the median third-income-quintile household's financial assets — would significantly curb retail participation. The market had already begun self-correcting: total single-stock leveraged ETF assets fell to about 1.7 trillion won from a June 25 peak of 2.4 trillion won. Investors who bought at the May 27 launch date are sitting on losses of 30% to 32%, while those who bought at the June 25 peak have lost 44% to 55%.
Leveraged ETF turnover in July has reached 54% of SK Hynix's daily trading volume and 24% of Samsung's, according to UBS, meaning ETF-related flows may have amplified stock-level volatility beyond what headline asset sizes suggest. The regulatory tightening should reduce this structural distortion over time, though near-term volatility is likely to remain elevated given uncertainty around AI demand and potential earnings revisions at Korea's two largest chipmakers.
Margin debt has declined to 33 trillion won from a peak of 38 trillion won, while investor deposits have risen to 110 trillion won, suggesting the broader leverage system remains manageable. The margin call receivable ratio rose to 3.8%, with broker receivables at 1.5 trillion won, but the margin-to-equity ratio remains stable at about 0.5%.
