The panic in the Korean market is being reported misleadingly
Korean market circuit breakers are a delayed reaction to US sell-offs, not independent panic, due to trading hour differences.
- Global market correlation remains high, with Korean equities acting as a lagging indicator for US downturns.
- Circuit breakers indicate significant volatility and potential continued downside pressure from US markets.
Yes, the KOSPI hit circuit breakers but this is largely a catch-up move following Friday’s sell-off in the US .
The Korean market’s regular session runs from 09:00 to 15:30 KST (20:00 to 02:30 ET), with extended/off-hours trading from 07:30 to 18:00 KST (18:30 to 05:00 ET).
US equities trade from 09:30 to 16:00 ET in the regular session with extended trading running from 04:00 to 20:00 ET.
So today’s move is less the Korean market pricing in what happened in the US after its own market had closed...
I disagree. People often get panicked when they see a 10% drop but forget that KOSPI is up like 80% YTD and over 150% from last year’s lows.
Beside the point. Apparently you missed how Korean market is supported by crazy leverage.
They expected to go up forever, when it started dropping, people began losing money they don't have, so they started selling ASAP, more people hit their stop loss and started selling -> doom loop.
They had to shut the market down because it was minutes away from plummeting with absolute panic.
If you can't handle a 10% drop in the market, you may have over leveraged yourself a bit...
The Korean "sidecar" circuit breakers are to stop automated/algorithmic trading software from going absolutely haywire (algorithmic selling/buying loops). They make it so an actual human has to take a look at what's happening. It's not related to individual investor panic.
It is time-to-buy-Lambo selling
I don’t think you can attribute it only to this. Kospi doesn’t like oil shocks either, missiles are flying and oil spiked.
Let's not forget the Korean market also went down on Friday.
Let's not forget the US chip stock companies also fell Thursday lol.
Nah the KOSPI was also down 7% on Friday. Its down another 7+% today... AI chip stocks Samsung and SK Hynix along with LG electronics are tanking. I wouldnt be surprised if AI chip related stocks on the nasdaq tank some more on US market open too. Pergaos the great correction is finally upon us?
Oh cmon let them feel smart because they finally understood how time zones work and feel the need to tell the entire world about it.
A 10% movement for KOSPI is just a normal Tuesday
I think 50% of the entire index is just 2 companies
Time to load up on skhynix
Aren’t many Korean traders also really degen.
Quite the opposite, lots of trading on margin
Today's KOSPI trades
- Domestic +15,045
- Foreign -8,441
- Institutes -8,693
Koreans are still very bullish.
