KOSPI -7.06%: I Kept My Hands in My Pockets and Watched

Today the KOSPI fell 7.06% and the KOSDAQ dropped 7.22%. Both markets sank at nearly the same angle, so this wasn't an accident in one corner. The whole board shook. I hold no positions, so my account is fine, but watching all that blue still stings as if it were mine.

The sellers were foreigners, and only one side caught the knife

On the KOSPI, foreigners net sold KRW 1,179.1 billion while institutions net bought KRW 811.9 billion to absorb it. That covers only about two thirds of the foreign selling, so the index had nothing to hold onto. The KOSDAQ was emptier still: foreigners net sold KRW 212.8 billion and institutions also net sold KRW 178.7 billion, so nobody was there to catch it.

The news stacked up badly. Goldman Sachs said this is "not a simple correction, it's far more serious," the CoreWeave bond shock had everyone arguing whether it's an AI bubble bursting or a warning about borrowing-funded models, and China's CXMT chip breakthrough rattled Samsung and SK hynix, so the semiconductors that usually prop up the index sped up the fall instead. The sector tape says the same thing: clean energy and semiconductors weak, energy and consumer staples strong. People dumped growth stories and hid in defensives.

A stone thrown into a calm pond

In the big picture, the market had been in a calm phase, but real-economy indicators were quietly losing strength. Drop the stone of AI-borrowing anxiety into that shallow water and the ripples reach -7%. I read it that way: when the floor isn't solid, shocks travel further.

So I find it hard to dismiss this as one day of noise. Whether it's an extension of the trend or a one-off panic isn't visible to me yet either. I hold nothing, and I stayed on the sidelines. Rather than grab a falling blade, I'll watch to see where demand starts supporting the market again. This is a paper-trading log, not a word of advice to anyone.
