Here’s the top reasons why the Kospi Index is falling today

The Kospi Index gapped lower on Wednesday as a global bond selloff weighed on risk appetite and heavy selling hit major technology stocks including Samsung Electronics and SK Hynix.

The index fell to around 6,473, roughly 10% below this week's high near 7,215.

South Korea long-term bond yields jump

The Kospi Index slumped, joining other top global benchmarks like the Nikkei 225 and Nasdaq 100.

South Korea's 30-year government bond yield rose to around 4.72%, extending a broader rise in long-term borrowing costs.

The move mirrors a global bond selloff driven by concerns over inflation, government debt and the outlook for interest rates.

Renewed uncertainty over US-Iran negotiations has added to those concerns.

Investors are increasingly wary that a resumption of hostilities could push oil prices higher, adding to inflationary pressure and potentially keeping interest rates higher for longer.

Brent crude rose above $91 a barrel on Wednesday, while West Texas Intermediate traded around $85.

Higher energy prices are particularly significant for South Korea, a major oil importer, because they can worsen the country's trade balance and add to inflationary pressure.

South Korean risks also jumped after Trump criticized the US defense pact with the country.

He praised North Korea’s Kim Jong Un and blasted South Korea’s president for not helping the US in its fight against Iran.

This means that South Korea may now be forced to boost its defense spending in the near term. 

Samsung and SK Hynix stocks are plunging

Meanwhile, the Kospi Index is also falling as its top constituent companies continue their strong downtrend.

Samsung Electronics stock dropped by 7.45%, while SK Hynix fell by 8.72%. As a result, SK Square, which holds a stake in SK Hynix, dropped by 10.84%.

This retreat coincided with the ongoing plunge in other top memory companies like Micron, Kioxia, and SanDisk.

All these companies have become highly volatile in the past few months as investors have remained concerned about their growth prospects.

Other top losers in South Korea were companies like Samsung Electr-Mechanics, Hyundai Motor, Samsung C&T, and Samsung Life Insurance. 

Kospi Index technical analysis

Kospi Index chart | Source: TradingView

The daily chart shows that the Kospi Composite Index has been in a slow uptrend in the past few weeks as technology companies rebounded. It moved from a low of 5,279 in July to a high of 7,215 points.

The index then gapped lower today, reaching a low of 6,493 today. On the positive side, it has still formed a bullish flag pattern, a common bullish continuation sign in technical analysis. It also sits above the 200-day Exponential Moving Average (EMA).

Therefore, the most likely scenario is where the index resumes rising and retests the resistance level of 7,215. A move above that level will point to more gains. If this fails, there is a risk that the index will drop further to 5,279.
