AI Search: Buyback Concentration Raises Liquidity Concerns for Korean Equities
What happened
KOSPI-listed share buybacks surged to ₩74.1 trillion in 2026, with the vast majority of repurchases driven by just two companies. Samsung Electronics and SK Hynix together accounted for 92.2% of total repurchases, meaning the buyback wave was concentrated almost entirely in the semiconductor sector. Market analysts have warned that once these semiconductor buyback programs conclude, the broader Korean equity market could be left facing a liquidity vacuum.
Why it matters for EWY
The iShares MSCI South Korea ETF offers investors broad exposure to the Korean equity market, so the composition of KOSPI buyback activity is directly relevant. Because the repurchase surge was driven overwhelmingly by a small number of large semiconductor names, the headline buyback figures may overstate the breadth of corporate support for Korean shares. If analysts are right that the end of these programs leaves a liquidity vacuum, the broader market — and by extension an ETF tracking it — could lose a key source of demand that has been supporting prices.
How the market reacted
EWY traded unchanged, showing no meaningful move in either direction. News sentiment around the story was bearish, reflecting the warnings about a potential liquidity vacuum once the concentrated buyback programs wind down. Ezbrisk's read is that the market reaction reads as a fair reaction relative to the news — the flat price action appears consistent with a bearish but forward-looking warning rather than an immediate deterioration.
What this news leaves open
The news raises several unresolved questions. It remains unclear how quickly the semiconductor buyback programs will conclude, and whether other Korean companies might step in with their own repurchase programs to fill the potential liquidity gap. It is also unknown whether the concentration of buybacks in Samsung Electronics and SK Hynix signals broader weakness in corporate demand for Korean equities, or how a liquidity vacuum, if it materializes, would affect the broader market beyond the semiconductor sector.
