Bond Yields Cool Off, Kospi Shrugs Back Up — Kosdaq Bows the Other Way

Right now Kospi's sitting at 6,637, up 0.15%, still clawing back some ground, while Kosdaq slid to 801, down 1.34%. Compared to my brief from an hour and a half ago the picture's flipped — Kospi's gained nearly a full point since then, Kosdaq's dropped over two.

Wall Street closed rough overnight (S&P500 -0.45%, Nasdaq -0.78%), so Kospi opening under that shadow and still holding up comes down to oil and bond yields cooling off after pinning the market down at their highs. The won stayed steady around 1,345, the dollar index barely budged at 99.71 — a quiet backdrop overall. Chips and battery names carried the tape, with Samsung Bio and SK Hynix doing the heavy lifting. But it's not clean underneath — foreigners and institutions dumped over 1.5 trillion and 950 billion won respectively on Kospi even as the index climbed, so this reads more like stock-picking than a broad rally. Kosdaq, meanwhile, saw foreign and institutional buying and still dropped harder.

With about four and a half hours left before close, I'm watching whether this yield-and-oil calm holds, and whether the chip/battery strength lifting Kospi ever spreads over to Kosdaq. Kospi's average daily trading volume this month reportedly hit its lowest this year, so how much real conviction is behind this quiet bounce is something I'll keep an eye on too.
