Asian stock markets have delivered impressive performance this year, yet surprisingly, the primary driver behind this rally has not been overseas capital. Goldman Sachs asserts that local retail investors are increasingly becoming a significant force in marginal market pricing. Take South Korea as an example: its market has surged 82% year-to-date, while foreign investors have been net sellers of approximately $62 billion over the same period. Japan presents a different pattern—the market has shown significant strength alongside an inflow of about $66 billion in foreign capital. Although foreign fund flows in these two countries are opposite, they share a commonality: local retail investors have consistently entered the market through channels such as spot trading, ETFs, and derivatives, essentially absorbing foreign selling pressure in South Korea and providing incremental support in Japan. Data from Goldman Sachs reveals that since late February, South Korean retail investors have accumulated net purchases of around $35 billion in stocks, with local ETF net inflows also reaching about $35 billion during the same period. More importantly, retail participation channels have expanded from spot trading to include ETFs, stock index futures, and single-stock futures, forming a more diversified funding base. This indicates that local capital is not merely playing the role of "buyers of last resort" but is gradually becoming a dominant force driving market gains. Goldman Sachs maintains a positive outlook on North Asian markets and believes that continued participation from retail funds will provide ongoing support. In terms of specific allocations, the firm is overweight on South Korean, Japanese, and Chinese markets, explicitly favoring A-shares over H-shares.
Foreign Outflows Do Not Equate to Market Pessimism While many investors view foreign capital outflows as a sign of declining risk appetite, Goldman Sachs argues that the current fund movements do not represent a typical risk-off shift. The report indicates that the South Korean market has experienced approximately $62 billion in net foreign outflows this year, but these outflows have been concentrated in a few heavyweight stocks rather than a broad sell-off across the entire market. Meanwhile, data from Goldman Sachs Prime Services shows that hedge funds, overall, continue to increase their allocations to South Korea and other North Asian markets. This suggests that recent foreign outflows are more akin to rebalancing by long-term funds based on index weightings and asset allocation, rather than a systemic bearish view on the region's prospects. Goldman Sachs believes this is also a key reason why the market has maintained its strength despite foreign capital reductions. Leverage Not at Extreme Levels, Sentiment Provides Multi-Dimensional Support As the market continues to rise, investors have begun to worry whether retail enthusiasm has evolved into a bubble. Goldman Sachs acknowledges that margin balances in North Asian markets have reached historical highs, and leveraged ETF assets have grown significantly—leveraged ETF assets in South Korea alone amount to approximately $30 billion. However, Goldman Sachs contends that current leverage levels remain manageable. When measured as a percentage of free-float market capitalization, related metrics have risen but have not reached historical extremes. Moreover, strict margin and financing regulations in the region impose constraints on leverage expansion. Therefore, while leveraged funds may amplify short-term volatility, they are not yet sufficient to pose systemic risks. Goldman Sachs further notes that this round of retail participation is not limited to fund inflows but is evident across multiple dimensions. Over the past year, new account openings in North Asian markets have shown noticeable growth, and small-cap stock turnover rates have increased significantly. The firm's constructed retail sentiment indicators reveal that participation enthusiasm is particularly prominent in the South Korean market, with Japanese and Chinese market sentiment also remaining positive. The growth in new accounts, increased trading activity, and sustained fund inflows collectively form important pillars of support for the current market.
