Asian Retail Investors: Seohak Ants to NISA and SIPs — 2026-09-06

Top developments

Korean Retailers Rotate from Chips to Leveraged ETFs

In early September 2026, Korean retail investors ("Seohak Ants") significantly reduced holdings in individual semiconductor stocks like Nvidia, Micron, and SK Hynix ADRs. Instead, they poured capital into leveraged ETFs, particularly the Direxion Daily Semiconductor Bull 3X Shares (SOXL), purchasing $430.95 million worth this month alone. This shift indicates a desire for amplified exposure to sector rebounds without single-stock risk, even as the KOSPI fell nearly 4% due to foreign and institutional selling.

Korean Retail Buying Plummets After July Rout

Retail net buying of domestic Korean stocks plunged to 5.4 trillion won in August, a tenth of the levels seen in June, as approximately 12 trillion won ($8.7 billion) of retail money left the market. This exodus followed a bruising home market correction, driving the biggest rush into US markets in six months and reviving risks to the won. The data highlights the fragility of domestic retail sentiment when faced with sustained volatility.

Japanese NISA Weekly Rankings Favor Index Funds

For the week of August 31 to September 4, 2026, Rakuten Securities' NISA account rankings showed continued dominance by broad index funds in both the "Tsumitate" (accumulation) and "Growth" investment categories. The weekly buy amount rankings highlighted steady accumulation into global equity indices, reflecting a persistent preference for passive, low-cost strategies among Japanese retail savers utilizing the new NISA framework.

Local view

Donga Ilbo (Korea) reports that "Seohak Ants" have sold major semiconductor individual stocks while buying leveraged ETFs, creating a divergent investment pattern where they bet on the sector's direction rather than specific companies. The article notes that this behavior reflects a high risk-tolerance profile among Korean retail investors despite regulatory tightening on single-stock leveraged products.

Newtalk News (Taiwan) highlights a paradox in Taiwan's high-dividend ETF market: while returns have been strong (up to 45% in some cases), the number of beneficiaries in 23 passive high-dividend ETFs dropped by approximately 489,000 people between January and August 2026. This suggests that many retail investors are taking profits or rotating out despite performance, possibly due to valuation concerns or better opportunities elsewhere.

Context & numbers

• Korean SOXL Holdings: Korean retail investors now hold approximately 27% of the total market capitalization of the SOXL ETF, making them the largest cohort of investors in this leveraged product.
• Korean Short-Term Bond Inflows: Amid rising interest rate concerns, Korean retail investors bought 125.6 billion won ($90 million approx) of US short-term bond ETFs in the past week, signaling a defensive pivot alongside their aggressive equity bets.
• Indian SIP Performance: Recent reports highlight that 10 mutual funds have delivered returns of over 20% on 10-year SIPs, with Nippon India Small Cap leading the pack, reinforcing the long-term efficacy of SIPs despite recent market volatility.

On the radar

• Korean Regulatory Watch: Monitor the impact of the increased minimum deposit requirement (30 million won) for leveraged single-stock ETFs, which has already removed these products from the top 50 net-buying lists in August.
• Taiwan ETF Dividends: Investors are watching the September dividend season for high-dividend ETFs like 00940, which is expected to pay a record-high 0.055 TWD per unit, potentially attracting renewed inflows after the recent beneficiary drop.
