China’s A-share market is shifting from a phase of broad liquidity expansion to one of ample existing liquidity but limited marginal inflows, according to a new strategy report from Huachuang Securities. The index may still grind higher, but the power of liquidity alone to stretch valuations has visibly faded. The fundamental driver of any future bull market, the brokerage argues, is migrating from monetary tailwinds toward earnings growth — and the question of “who provides the next wave of capital” has become the market’s defining puzzle.

Huachuang’s baseline scenario holds that the A-share market does not lack potential incremental capital in aggregate. Rather, the era in which — as seen in the second quarter — a relentless flood of new money rapidly inflated sector valuations has likely passed. The market is transitioning toward a structure of “abundant stock, differentiated flows.” Breaking this baseline requires one or more of four catalysts: sustained allocation from institutional investors under pressure from the liability-side interest spread squeeze; fresh foreign inflows triggered by an easing in financial conditions; an expansion of mutual fund liabilities; or a restart of household deposit migration into equities.

Should foreign capital, mutual funds, and household deposits all ignite simultaneously, the market could re-enter a phase of aggregate liquidity expansion, reopening both the slope and the ceiling of index appreciation.

Eight Sources of Capital, Each Playing a Distinct Role

Huachuang identifies eight categories of incremental capital, each with its own rhythm, risk appetite, and market impact:

1. Insurance funds — capital with high certainty but a smooth, gradual pace. Under regulatory “hard constraints” pushing large state-owned insurers to allocate 30% of new premiums to A-share investment, Huachuang projects insurance capital to contribute roughly 549 billion yuan in incremental space over the next 6–12 months. The pace will accelerate if the liability-side spread pressure widens or new premium growth surprises to the upside.

2. Foreign capital — continuous strategic overweighting as Chinese assets’ relative appeal grows, likely to accelerate on a stabilising and appreciating RMB and a narrowing China-US interest rate differential.

3. Private funds — performance-driven, structurally elastic capital. Their acceleration hinges on a positive feedback loop: AI-led tech rallies rebuild performance, which in turn drives new subscriptions.

4. Leveraged funds (margin financing) — emotional amplifiers under upgraded risk controls. After the sharp deleveraging of July, margin sentiment is slowly healing, with total volume expected to expand gently and structurally cautiously.

5. ETFs — catalysts for consensus around industrial trends. While broad-based scale ETFs have acted as counter-cyclical stabilisers over the past two years, future incremental space is expected to tilt toward industry- and theme-based ETFs as carriers of industrial-trend capital.

6. Household deposit migration — a lagging incremental force that accelerates only after profit-making effects spill over broadly to retail investors. This channel is currently in a phase of temporary moderation.

7. Mutual funds — reparative incremental capital that returns as profit-making effects revive. New fund issuance may rebound, but its susceptibility to market swings means mutual fund inflows are more of a repair dynamic than a steady, normalised flow — inherently less persistent than insurance money.

8. Asset management products (trusts, bank wealth-management products, brokerage asset-management plans) — low-risk-preference, follow-on capital that is most sensitive to volatility and enters only after profit-making effects are firmly established.

The Four-Stage Relay: From Short-Term Money to Long-Term Anchors

Huachuang argues that incremental capital over the next six months will most likely enter through a relay race: short-term funds ignite the move → industrial-trend funds take the baton → household and prudent capital diffuse outward → long-term funds provide the floor. This progression is essentially a gradual switch in risk appetite from high to low and in decision-making horizons from short to long. It will also drive a market style rebalancing — from high-elasticity thematic plays toward core assets with earnings support and dividend-paying blue chips offering stable returns.

Each type of capital shapes the market differently: margin financing and private funds determine short-term elasticity; mutual funds and ETFs determine structural direction; household deposit migration determines the upper bound of market space; and long-term funds such as insurance determine the bottom-line support.

Stage One — Counterattack Launch: Trading-oriented funds lead. As the market reverses from a bottoming consolidation, the primary marginal increments come from the fastest-reacting margin and private funds. They determine the slope, not the direction; they amplify short-term amplitude but cannot independently sustain a trend. Their impact manifests primarily as periodic volatility magnification.

Stage Two — Profit-Making Effects Emerge: Industry- and theme-ETF, mutual fund, and foreign capital take the baton. As the rebound persists and profit-making spills from isolated hotspots into related industrial chains, capital increments broaden. The market transitions from thematic rotation toward more industrially-logical main lines, with pricing efficiency and capital focus both rising markedly.

Stage Three — Trend Confirmation: As profit-making diffuses to wider household cohorts, deposit migration and prudent asset-management products become the dominant marginal increments. This stage features broad-based diffusion, elevated turnover, and a style shift from pure high-elasticity themes toward a “dumbbell” allocation of dividend-low-volatility and large-cap blue chips.

Stage Four — High-Level Maturation: Long-term capital represented by insurance comes to the fore. Throughout the entire market cycle, insurance money maintains a steady inflow. When the marginal inflow velocity of all other capital types slows in Stage Four, insurance becomes one of the few forces still capable of providing continuous marginal support. Its long-standing preference for high-dividend assets offers substantive bottom-line support during volatility, reducing both the depth and duration of corrections.

Risks to the Thesis

Huachuang cautions that macroeconomic recovery may fall short of expectations; historical patterns do not guarantee the future; and the capital-flow projections rest on multiple key assumptions tied to overall market judgements. If those assumptions deviate from reality — or if market conditions change violently — actual outcomes may differ materially. The four-stage transmission is an ideal-path construct, not an inevitable forecast. Its full unfolding depends on multiple conditions: corporate earnings repair, domestic liquidity environment, foreign risk appetite, and the restoration of household risk appetite. The market faces black-swan risks from volatility and geopolitical conflict that could alter the rhythm of capital flows at any time.
