Add fuel to the fire! The world-leading South Korean stock market is about to welcome American retail investors' funds.

```

Since the beginning of this year, the South Korean stock market has topped major global markets with a rise of more than 75%, and it is now set to welcome incremental funds from American retail investors.

Recently, one of the largest online brokers in the U.S., Interactive Brokers, announced that it is opening direct trading channels for Korean stocks to American retail investors.

Interactive Brokers stated that eligible global clients can now directly trade Korean stocks through its platform, supporting same-day account opening, real-time execution, and institution-level transparent pricing, and claims to be the first large American brokerage to offer such services.

The opening of this direct trading channel is expected to accelerate the influx of individual American investors into the Korean market. Previously, American retail investors could only invest in the Korean market by trading ETFs listed in New York or a limited number of American Depositary Receipts (ADRs) of Korean companies.

According to Bloomberg, during IBKR's pilot run, global investors have poured almost record amounts of funds this week into Korea's benchmark index components. Seoul hedge fund Petra Capital Management partner Chan H. Lee stated:

Many people are excited about the opportunity to directly access the Korean market.

Highest gains in the world, South Korean stock market repeatedly breaks milestones

The strong performance of the Korean stock market in 2026 continues. The Korea Composite Stock Price Index has risen more than 75% this year, not only leading major global markets but also nearly matching last year’s historic increase.

This rally has repeatedly set new records. The total market capitalization of the Korean stock market has soared 71% this year to $4.59 trillion, successively surpassing the UK, France, and Germany, and recently overtaking Canada to become the seventh largest stock market in the world.

Meanwhile, Canada saw gains of only about 7% this year, with a total market capitalization of around $4.5 trillion.

Samsung Electronics' market cap recently exceeded $1 trillion, and SK Hynix's share price has more than doubled this year. Together, they account for about 45% of the Kospi Index’s weight, serving as the core engines driving Korea’s market cap surge.

Eugene Asset Management Chief Investment Officer Ha SeokKeun said:

Driven by the AI-powered memory chip cycle, Korea’s market capitalization is expected to expand further, while Canada’s market is constrained by its heavy concentration in energy and finance, with relatively limited room for growth.

Beyond semiconductors, earnings forecasts for non-chip companies accelerate simultaneously

The forces driving the Korean market are no longer limited to semiconductors. Foreign investors are now turning their attention to sectors such as power, defense, and shipbuilding to capture opportunities from Korean industrial competitiveness.

According to dynamic tracking data of analyst forecasts, excluding Samsung Electronics and SK Hynix, expectations for 2026 earnings per share growth of Korean listed companies have surged from about 20% at the start of the year to 48% by mid-April—a more than doubling of growth in less than four months.

Notably, this optimism is focused on the near term; earnings forecasts for 2027 have seen virtually no significant upward revision over the same period and remain in a narrow range of 14% to 15%.

This “hot now, cold later” pattern means the market highly recognizes the current performance momentum of Korea’s non-chip sectors, but has not yet extrapolated this unexpected growth linearly into the more distant future.
