Asian Retail Investors: Seohak Ants to NISA and SIPs — 2026-09-03
South Korean retail investors have poured approximately 10 trillion won into US stocks over the past two months, with a significant portion concentrated in leveraged ETFs like SOXL, prompting US exchanges to restrict price data feeds for some tickers. Meanwhile, Japan's NISA system continues to attract young investors, with purchases by those in their 20s surging 17-fold since inception, and Taiwan's high-dividend ETFs hit record highs ahead of a massive September dividend season.
Asian Retail Investors: Seohak Ants to NISA and SIPs — 2026-09-03
Top developments
Korean Retail Flows Surge to 10 Trillion Won in Two Months
Data released around August 30, 2026, indicates that South Korean individual investors net-purchased approximately 10 trillion won ($7.3 billion) in US stocks between July and August. This outflow from the domestic market coincides with the Kospi's correction, with retail buying exceeding net purchases in the local KOSPI market for the same period. The trend highlights the continued "Seohak Ants" (Western Ants) preference for US exposure despite regulatory pressures.
US Exchange Restricts SOXL Price Feeds Due to Korean Volume
In a significant move affecting leveraged trading, US exchanges have reportedly suspended weekly price data provision for certain tickers heavily traded by Korean investors, including the Direxion Daily Semiconductor Bull 3X Shares (SOXL) and others like KORU. Maeil Business Newspaper reported on September 1 that this action was likely triggered by SEC regulations regarding data provision limits when foreign investor concentration exceeds certain thresholds. This development underscores the sheer dominance of Korean retail capital in specific leveraged ETF products.
SOXL Holdings by Korean Investors Reach 27% of Market Cap
According to a report published on September 3 by Sisajournal, Korean retail investors now hold approximately 27% of the total market capitalization of SOXL. This concentration has made them "big hands" in the US leveraged ETF market. The report notes that while single-stock leveraged products have seen reduced activity due to new domestic regulations raising the minimum deposit requirement to 30 million won, demand has shifted aggressively toward index-based leveraged ETFs.
Japanese NISA Purchases by Young Investors Surge 17-Fold
New data compiled by Japan's Financial Services Agency and reported by BigGo Finance in late August reveals that annual NISA purchases by investors in their 20s have surged 17-fold since the program's launch, reaching ¥1.2 trillion in 2025. This demographic shift is critical for Japan's asset management industry, as it represents a long-term structural inflow into equity funds. Recent commentary from CBC Television (September 3) also highlights ongoing discussions about optimizing monthly contribution amounts under the new NISA framework.
Taiwan ETFs Hit Record Highs Ahead of September Dividend Season
Taiwan's high-dividend ETFs, such as 0056 and 00919, hit all-time highs in late August and early September, driven by strong AI-related sector performance and anticipation of dividend payouts. ETtoday reported on September 2 that 0056 reached a record price, with over 1.65 million beneficiaries. The momentum is fueled by a massive dividend season starting mid-September, where 33 stock-type ETFs will go ex-dividend, with 21 of them doing so on September 16 alone.
Local view
Sisajournal (Korea): The outlet describes Korean retail investors as becoming the "big hands" (major players) in the US leveraged ETF market, specifically noting their disproportionate influence on SOXL. The article warns that this concentration is so high that it has triggered structural responses from US exchanges, including data feed restrictions.
Maeil Business Newspaper (Korea): The paper reports exclusively that US exchanges have stopped providing weekly price data for SOXL and other Korean-favorite tickers. It suggests this is due to SEC rules limiting data provision when foreign ownership or volume exceeds specific caps, effectively creating "blind orders" for these assets and potentially dampening future investment enthusiasm.
CBC Television (Japan): In a segment aired on September 3, financial planners discussed whether the current NISA structure remains optimal for the 2026 economic environment. They highlighted the need for individuals to review their contribution amounts and asset allocation between the "Tsumitate" (accumulation) and "Growth Investment" slots, reflecting a maturing sentiment among early adopters.
