AI Infrastructure Boom Propels South Korean Stock Market Toward Historic Heights
As the Kospi continues its relentless upward march, financial analysts are aggressively raising their targets, with predictions now suggesting the benchmark index could soar as high as 11,700 points by the end of the year. Experts attribute this unprecedented bullish momentum to a massive structural supercycle in artificial intelligence (AI) semiconductors. Reflecting this optimism, target prices for Samsung Electronics and SK Hynix—the twin engines of the South Korean stock market—are being revised upward at an extraordinary pace.

On June 1, DB Financial Investment projected that the South Korean stock market will sustain its historic rally, fueled by non-stop global investments in AI infrastructure. The brokerage estimated that the Kospi could easily breach the "10,000-point milestone" in the second half of the year, potentially stretching to a peak of 11,700 points.

Turning Capital Costs into Explosive Returns
"With the surge in generative AI services catalyzed by OpenAI and the aggressive capital expenditure from global hyperscalers building massive data centers, South Korea’s semiconductor export growth is hitting historic milestones," noted Kang Hyun-gi, a senior researcher at DB Financial Investment. "For a stock market rally to be fundamentally sustainable, macro-investment returns must outpace capital costs. Currently, global macroeconomic indicators show this condition is being overwhelmingly met."

Taking the U.S. Federal Funds Rate as the benchmark for capital costs, the current nominal U.S. Gross Domestic Product (GDP) growth rate—which serves as a proxy for capital return—stands at 6% year-on-year. This significantly outpaces the borrowing cost of 3.75%, providing a highly favorable macroeconomic backdrop for equity markets.

"The structural signals for the market leaders in the semiconductor sector remain unequivocally bullish, ensuring that South Korea's upward momentum has plenty of room to run."

Considering these optimal domestic and international factors, DB Financial Investment widened the expected trading range for the Kospi in the second half of the year, setting the floor at 7,700 points and the ceiling at 11,700 points.

Brokerages Uniformly Reset Target Projections
DB Financial Investment is far from alone in its hyper-bullish outlook. A chorus of major financial institutions is now forecasting that the Kospi will establish a solid footing well above the 10,000-point threshold.

Global investment banking heavyweights have joined the chorus as well. Both JP Morgan and Morgan Stanley have set their bull-case scenarios for the Kospi at a historic 10,000 points. At the heart of this market-wide re-rating are Samsung Electronics and SK Hynix, recognized globally as the primary beneficiaries of the AI memory boom.

Massive Target Hikes for Tech Giants
On the corporate front, SK Securities issued a bold report on June 1, predicting that the current semiconductor upcycle will enjoy unprecedented longevity. The firm drastically increased its target price for Samsung Electronics to 610,000 KRW and SK Hynix to 4,000,000 KRW. Given that the two stocks closed at 349,000 KRW and 2,363,000 KRW respectively on Monday, these projections suggest the tech giants could nearly double their market caps from current valuations.

"Securing long-term supply agreements (LTAs) has provided these tech giants with high demand visibility for the next three to five years, while establishing a robust price floor that guarantees earnings stability," explained Han Dong-hee, an analyst at SK Securities. "Furthermore, the price of High Bandwidth Memory (HBM) is expected to rise by at least 50% next year compared to this year, dragging the entire memory sector into an era of prolonged, structural prosperity."

Looking further ahead into 2027, SK Securities upwardly revised its operating profit forecasts to an astonishing 570 trillion KRW for Samsung Electronics (a 10% upgrade) and 423 trillion KRW for SK Hynix (a 13% upgrade).

Foreign institutional investors are moving in lockstep. Nomura Securities recently updated its price targets, bumping Samsung Electronics from 340,000 KRW to 590,000 KRW, and SK Hynix from 2,340,000 KRW to 4,000,000 KRW. Nomura emphasized that both corporations should no longer be viewed through the lens of cyclical tech stocks, but rather re-rated fundamentally as 'structural growth stocks' due to the permanent shifts in global AI memory demand.
