South Korean Retail Investors Drive US Equity Surge, Holdings Near $200 Billion Fueled by AI Stocks
South Korean investors are rapidly becoming a dominant force in US equities, with their American stock holdings now approaching an impressive $200 billion. This significant surge positions them among the globe’s most aggressive and influential buyers of top artificial intelligence companies, profoundly impacting Wall Street.
Despite this remarkable growth and their formidable presence on Wall Street, Lee Young-gon, Head of Research at Toss Securities, notes that South Korean investors are still in the nascent stages of their journey into US equity investments.
In a recent interview with The Korea Herald, Lee explained, “Korean retail investors have only recently begun allocating substantial capital to the US market, a trend that’s just a few years old.”
He reiterated, “Korea, in many respects, remains in the foundational phases of US equity investment.”
This growth trajectory has been exceptionally rapid. From a mere $4.66 billion in US stock holdings in 2018, Korean investor capital doubled to $8.42 billion in 2019, then dramatically surged to $37.34 billion in 2020, and has continued its ascent to an astounding $193.74 billion by June.
While this substantial sum still accounts for approximately 0.2 percent of the massive $75 trillion US stock market, South Korean investors exhibit considerably greater influence within specific high-profile equities. Notably, they have occasionally appeared among the largest shareholders of companies like Tesla, standing alongside global investment giants such as BlackRock and Vanguard.
Lee attributes this impact to a key characteristic: “Korean retail investors typically concentrate their investment portfolios.”
Despite their increasing influence in public markets, South Korean investors frequently face exclusion from highly coveted private-market investment opportunities, exemplified by ventures like SpaceX. This challenge may persist, especially as investors keenly anticipate potential future initial public offerings (IPOs) from emerging AI sector leaders such as OpenAI and Anthropic.
However, Lee anticipates a gradual shift in this dynamic, predicting that global issuers will increasingly acknowledge the substantial scale and growing influence of Korean capital on the world stage.
He emphasized, “The sheer volume of Korean investment can no longer be deemed insignificant. My hope is that South Korean investors will gain the recognition they deserve and not be overlooked in future opportunities.”
This burgeoning trend in overseas investing has also significantly transformed Toss Securities. Capitalizing on the escalating South Korean appetite for US equities, the brokerage firm has successfully surpassed numerous larger competitors in the realm of international stock trading. Last year, Toss Securities achieved an industry-leading position, generating 449.4 billion won ($293 million) in overseas stock custody commission revenue.
During the first quarter, overseas stock commissions experienced a robust 43.5 percent year-on-year increase, reaching 124.4 billion won. This substantial rise contributed to a phenomenal 117 percent leap in operating revenue, totaling 340.5 billion won, while operating profit simultaneously climbed 34.3 percent to 111.7 billion won.
A pivotal factor underpinning this success is Toss Securities’ innovative fractional share trading service, introduced in 2022. This service empowers investors to acquire portions of typically high-priced US stocks, making diverse portfolios accessible with relatively modest capital investments.
Despite a recent trend where an increasing number of South Korean investors have reallocated capital back into domestic equities, spurred by a strong rally in the local stock market and government-backed tax incentives, Lee firmly emphasized the enduring importance of US stocks as a core component of long-term investment portfolios.
He affirmed that artificial intelligence (AI) continues to be the preeminent theme across global markets, noting that the pioneering companies defining and advancing this transformative industry remain predominantly concentrated within the United States.
Lee stated, “While certain Korean chipmakers are undoubtedly benefiting from the expansive AI boom, the foundational companies that are truly shaping and leading the entire AI industry are predominantly based in the US.”
He concluded, “From a strategic long-term investment perspective, continuous exposure to the US market is essential for investors, as it hosts a broader spectrum of companies poised to significantly benefit from the sustained growth of AI.”
Bringing over 25 years of extensive industry experience, Lee began his distinguished career as an analyst at Hanwha Investment & Securities in 2000. His professional journey also includes tenures at Hana Securities and a significant role as Chief Investment Officer at KNT Investment, prior to his appointment at Toss Securities in 2023.
