According to an analysis by a fund manager at China Merchants Fund, the recent rally in small-cap stocks is driven by four primary forces. First, a technical rebound followed a significant correction, with the CSI 1000 Index experiencing a maximum drawdown of over 25%, creating inherent momentum for a bounce-back. Second, long-term capital has been making contrarian allocations, with CSI 1000-linked ETFs seeing sustained large net inflows, providing a liquidity base for small-cap stocks.
Third, the extreme crowding in the large-cap style has reached a critical point, triggering a convergence. The crowding level for small-cap factors once dropped to a historic low of -1.00, making the extreme overcrowding in large caps a precondition for a style rotation. Fourth, a broad monetary easing cycle, combined with a rebound in tech and growth stocks, has lifted risk appetite. Small-cap stocks naturally exhibit greater elasticity during periods of sentiment recovery.
Assessing the Rally's Sustainability
Whether the rally is sustainable requires cautious optimism. While there is a foundation for the rebound to continue, it will likely unfold as a structural repair process with wide fluctuations. The core support for sustainability comes from fundamentals: the full-year consensus estimate for net profit growth of the CSI 1000 Index is 25%, significantly higher than the approximately 8% for the CSI 300 Index. This profit growth gap is at its widest in recent years, serving as a fundamental anchor for small-cap outperformance. Additionally, valuation digestion in small and mid-cap stocks limits the downside potential for the index.
A key concern, however, is that the liquidity disadvantage of micro-cap stocks will be amplified in a low-turnover, stock-picking market. Therefore, the mid and small-cap stocks represented by the CSI 1000 Index are expected to perform more steadily than extreme micro-cap names.
Market Outlook
The A-share market is likely to transition from the "pyramid-style concentration" seen in the second quarter to a "dumbbell-plus-diffusion" mixed structure. The market is expected to maintain wide fluctuations in August, with small and mid-cap stocks potentially outperforming periodically, though the process will have its setbacks. Stock selection must be validated by interim earnings reports.
Four major catalysts to watch include: first, the acceleration of mergers and acquisitions, with 100 A-share companies changing their actual controllers this year, making small and mid-cap companies prime targets for industrial capital and state-owned enterprises. Second, the realization of earnings from hard-tech AI sectors, including computing power, semiconductor equipment, and humanoid robots, where order volumes are rising, and the interim report season is a key period for verification. Third, continued policy and liquidity support, focusing on whether net inflows into CSI 1000-related ETFs can persist, the pace of monetary easing, and the timing of policies for specialized and new "little giant" companies.
Summary
Whether the current rally can evolve into a larger bull market depends on three factors: the sustainability of capital inflows, whether interim earnings can validate the profit growth gap, and whether the crowding level in the tech thematic can decrease further, freeing up capital to flow into small and mid-caps. All three factors are currently moving in a favorable direction, but each step requires data verification. For the CSI 1000 enhancement strategy, a diversification of Alpha factors and strict risk control are employed to try to generate stable excess returns for holders.
