KOSDAQ Fell 3.26%, Twice KOSPI's Drop: Why Did Small Caps Sink Harder?

KOSDAQ -3.26%, KOSPI -1.46%.

On October 26, KOSDAQ fell more than twice as much as KOSPI.

All figures are based on confirmed closing prices for 2026-10-26, collected at 08:20 on October 27.

Retail investor:

"Why does KOSDAQ hurt so much more than KOSPI..."

Let's start with what the news actually confirms.

How far did each index fall?

KOSDAQ: 727.21 (-3.26%)

KOSPI: 5,469.47 (-1.46%)

The gap in declines is 1.8 percentage points.

It was a day when the indexes were shaken hard.

Why did the two markets split this time?

Here is what the headlines confirm.

→ Semiconductors: Samsung Electronics and SK hynix fell together, with broad weakness

→ Mid and small-cap chips: Buying concentrated in AI and HBM beneficiaries, with stock picking

→ Robotics: Rose even as the index crashed 3%

One side sold off while the other rose.

Still, the headlines alone don't let us pin the gap on a single cause.

What happened in the US overnight?

Energy: +2.60%

IT and semiconductors: +0.49%

Real estate: +0.12%

Consumer discretionary: -1.66%

Communication: -1.78%

Consumer staples: -1.92%

Energy led, while consumer and communication names lagged.

IT and semiconductors edged up 0.49%.

The question for today's open is whether chips follow that lead.

What to watch at today's open

→ 1. Whether HBM-related stocks, weak yesterday, try to rebound

→ 2. Whether KOSDAQ's decline narrows faster than KOSPI's

→ 3. Whether robotics strength continues or pauses

Fed rate expectations: 93% chance of a hold at the October meeting (Polymarket)

The view leans toward rates being a modest factor.
