KOSPI 200 (KODEX 200)

Buy KODEX 200 (KOSPI 200 ETF). The article shows a broad risk-on move tied to easing Iran escalation (lower oil/inflation risk) plus strong technicals: Kospi is above its ascending trendline, and holding above the 50/100-day EMAs and Ichimoku cloud. With the index near the all-time high, momentum can carry it toward KRW 8,925 and then the KRW 10,000 psychological level.

Key Risk: Trump reverses again and Iran escalation spikes oil prices, instantly breaking the risk-on/inflation relief story.

Samsung Electronics (005930)

Buy Samsung Electronics. It’s the clearest large-cap beneficiary in the piece (up ~12%) and it’s a high-liquidity way to own the tech-led surge. If the market is rotating into “AI/tech growth” ahead of major global tech events (SpaceX IPO), Samsung typically catches incremental flows, and the broader Kospi breakout supports follow-through.

Key Risk: Semiconductor demand expectations roll over (or a major export/geo-policy shock hits chips), causing tech leadership to fade even if the index stays strong.

  • The Kospi Index jumped by nearly 10% today.
  • The rally coincided with the Wall Street surge on Thursday.
  • Crude oil prices retreated sharply after Trump’s new statement on Iran.

The Kospi Composite Index jumped by nearly 10% today, June 12, and moved closer to the all-time high. It jumped to KRW 8,430, a few points below the record high of KRW 8,925. This article highlights the top reasons behind the rally in South Korean stocks.

Kospi Index jumps after President Trump’s statement on Iran

The Kospi Composite Index surged, mirroring the performance in global stocks. In the United States, the Dow Jones, Nasdaq 100, and S&P 500 indices jumped by over 1.75%. 

Similarly, other global indices like the Hang Seng, Shanghai, and NIFTY 50 also resumed rising on Friday.

The rally is happening after President Trump sent mixed signals on the Iran war. In his first statement on Thursday, he warned that he was planning a major assault against Iran, including taking Kharg Island, where Iran exports over 90% of its oil.

Such a move would mark a major escalation, leading to higher crude oil prices as Iran has vowed to respond more harshly. For example, Iran can hit all major energy plants in the region, including in countries like Saudi Arabia, Qatar, and Kuwait.

Iran also has tools in place to shut down the Red Sea, where 12% of oil passes through. It can do that directly by launching attacks against ships, and also by using Houthis. Just this week, Yemen warned that it would block all Israeli-linked ships from entering the region.

Trump then changed his mind on Thursday and said that he had canceled his planned attacks. He also said that the US and Iran were close to a deal that will be signed in Europe as soon as this week. 

To be clear: this is not the comprehensive deal that Trump has always wanted. Instead, it is a deal to start nuclear talks and reopen the Strait of Hormuz. A comprehensive Iran deal will be negotiated after that, with Trump keen on having a better one than the JCPOA.

A deal that reopens the Strait will be good for South Korea as it would lower crude oil prices and inflation. 

Technology stocks lead ahead of the SpaceX IPO

The Kospi Index is also rising as investors wait for the upcoming SpaceX IPO, which is set to happen later today. The company has already raised over $75 billion in assets, with reports suggesting that it has received orders worth four times than that. In its first report, Oppenheimer boosted its target for the stock, pointing to this demand.

As a result, technology companies have done well today. Samsung Electronics, the biggest South Korean company by far, jumped by 12%. SK Hynix jumped by 8%, with its market cap nearing the $1 trillion mark. 

SK Square, which owns a large stake in SK Hynix, jumped by 13%. The other top gainers were companies like Hyundai Motor, Samsung Life Insurance, Samsung C&T, and KB Financial.

The daily chart shows that the Kospi Index has jumped in the past few days. It has moved above the ascending trendline that connects the lowest swings since May 4 this year. 

The index has also held steady above the 50-day and 100-day Exponential Moving Averages (EMA). It jumped above the Ichimoku cloud indicator. 

Therefore, the most likely scenario is where it continues rising, potentially to the year-to-date high of KRW 8,925. A move above that level will point to more gains, potentially to the key resistance at KRW 10,000.
