KOSDAQ -3.26% Crash, Yet Battery ETFs Lead: Why Did Secondary Battery Stocks Rise?

KOSDAQ closed down 3.26%, and KOSPI down 1.46%.

On a day when almost everything fell, secondary battery stocks became the talk.

Both index figures are confirmed closes for October 26.

The news and moves below were collected as of 2026-10-27 14:30 KST.

Retail investors are asking the obvious question.

"Everything fell, so why is the battery sector being talked about?"

Let's go through the headlines one by one.

Why Did Secondary Battery Stocks Rise?

"Chinese ESS makers give up on US business."

That article is what sparked the rally in domestic battery names.

ESS, or energy storage systems, are large battery installations that store electricity.

A headline says a Chinese rival is pulling out of the US market.

That is likely why domestic battery stocks caught investors' eyes.

You should check the full article for the details.

Why Do Battery ETFs Top the Return Rankings?

The headline says batteries swept the top spots in 3-month ETF returns.

The 3-month window reflects recent trends, not a single day's move.

Whether batteries held up on a down day for the index needs to be checked separately through stock-level prices.

Is There Bad News Too?

Yes.

Lithium supply is growing, and EV demand is slowing.

A headline on the same day also flagged wobbling secondary battery stocks.

The signals are mixed.

There is also a headline that global tech fell on AI funding concerns.

How Is the Market Mood?

US sector moves (most recent trading day)

Energy: +2.60%

IT and Semiconductors: +0.49%

Consumer Discretionary: -1.66%

Consumer Staples: -1.92%

Only energy rose strongly, while consumer sectors lagged.

On Polymarket, the "yes" bet on no rate change after the October meeting stands at 94%.

So, Up or Down?

Downside factors

• KOSDAQ -3.26%, confirmed 10/26, index pressure
• Lithium supply expansion, slowing EV demand, wobbling
• AI funding concerns, continued weakness in global tech

Support factors

• Chinese ESS makers exiting US business, easing competition
• Battery ETFs, top 3-month returns
• Rate hold, Polymarket "yes" at 94%

I'll look at intraday prices and volume by stock first.
