很多同行消失了
Zhong Guo Ji Jin Bao· 2025-11-09 13:02
【导读】"很多同行消失了!"单一策略遇冷,私募转型多策略 "原来跟我们一批做CTA的,很多都已经消失了。"一位以CTA策略起家的私募负责人感慨道。据他透 露,国内一家规模曾超百亿元的CTA策略私募,如今规模已萎缩至不足5亿元,已搬到隔壁办公楼,而 更多同期成立的机构早已没了声音。 不仅是CTA私募,还有债券、主观多头等管理人,也以不同方式布局多资产领域,发行多策略产品。其 背后的逻辑是,单一策略收益率下行,或容量有限,抗风险能力不足,通过多资产、多策略布局,可以 实现风险的分散与收益来源的多元化。 记者了解到,私募转型多策略并非易事,需要重塑一套投研框架,对投资团队、交易系统与风控标准提 出更高要求。私募看好多策略的崛起,逐步从小众走向主流。最新备案数据也印证了这一转向,今年10 月,多资产策略私募产品备案数量达到122只,占比升至12.27%,仅次于股票策略。 CTA策略曾是私募行业的"明星赛道",但单一策略的局限性如今愈发凸显。 "光做CTA还是不够丰富,天花板太低了。"前述私募负责人表示,核心原因在于期货市场容量有限,远 不及股票市场的体量。这几年,不少CTA私募规模缩水明显,反观股票类私募,今年诞生了 ...

Core Insights - The value of FOF (Fund of Funds) allocation strategies is being reinforced in the current market environment, with a rapid increase in its share among high-net-worth clients' asset allocations [1][2] - The FOF strategy is expected to become a mainstream asset allocation tool in the domestic market, driven by a large fund product market, long-term capital inflows, and improved investor awareness [2][3] FOF Development Potential - The demand for wealth management is shifting from "single appreciation" to "stable diversification," making FOF strategies increasingly attractive due to their multi-asset and multi-strategy advantages [1][2] - The domestic market has a rich base asset pool, with non-monetary public fund scale exceeding 22 trillion yuan and private fund scale exceeding 12 trillion yuan [2] Multi-Dimensional Allocation Framework - FOF strategies require investors to set target volatility based on their risk tolerance, forming a three-layer framework of "macro direction, mid-level strategy selection, and micro fund selection" [3] - The FOF strategy allows for diversified asset allocation and strategy dispersion, mitigating extreme risks from single assets while capturing multi-dimensional returns [2][3] Risk Control Mechanism - The core of FOF risk control lies in "double dispersion," which provides a more robust safeguard compared to traditional funds that only diversify single asset risks [4][5] - The first layer of dispersion involves diversifying underlying fund assets, while the second layer focuses on diversifying strategies and managers to avoid "same-source risk" [5] Future Outlook - The potential for FOF products in the domestic market is significant, with expectations for the introduction of quantitative and hedging strategies to enhance risk-return profiles and product attractiveness [5]

Currently, the profits of most commodities are at relatively low levels in reality. In terms of expectations, the price level has basically bottomed out, and policy support and demand recovery will continue to boost inflation. Globally, fiscal and monetary policies are gradually entering a synchronous expansion cycle. Therefore, the long - term trend of the commodity market is gradually taking shape, volatility is expected to gradually increase, and the profit expectation of CTA is gradually strengthening [2]. - The short - to medium - term strategy environment is moderately favorable. Intraday liquidity has continued to recover, with a historical quantile of around 0.7; intraday volatility has remained high, with a historical quantile of around 0.9; and trend smoothness has slightly improved, with a historical quantile of around 0.7.

The precious metals and non - ferrous metals indices increased, while the energy and chemical, industrial products, agricultural products, and black indices decreased. Among stock index futures, the IC, IF, and IH indices rose, and the IM index fell. Treasury bond indices generally declined. For CTA style factors, the 20 - day time - series momentum and long - short 50% roll - over factors performed best, while the 20 - day cross - sectional momentum and 5 - day time - series momentum factors performed worst [6]. - **Commodity market**: The net value of most commodity sector indices declined, and most volatilities increased.

All types of CTA strategies posted small profits. For example, the China Merchants Futures CTA short - to medium - term strategy index rose 0.06%, and the medium - to long - term strategy index rose 0.36% [28][38]. 02 Strategy Market Environment - **Short - to medium - term strategy environment**: Intraday liquidity continued to recover, and volatility remained high.

Core Viewpoint - The article presents a metaphorical exploration of various investment strategies in the private equity space, likening them to legendary weapons, each with unique strengths and weaknesses, suitable for different market conditions and investor preferences [2][6]. Group 1: Investment Strategies - The first strategy, "Qinglong Yanyue Dao" (Subjective Long), relies heavily on the fund manager's ability to select stocks and time the market, performing well in bullish markets with clear themes [9][10][15]. - The second strategy, "Xuedizi" (Quantitative Long), utilizes complex algorithms to identify stocks based on specific metrics, excelling in active markets with high trading volumes [18][20][23]. - The third strategy, "Zhuge Lian" (Macro Hedging), involves top-down asset allocation across stocks, bonds, and commodities, generally effective in diverse market conditions but can fail during extreme events [26][30][31]. - The fourth strategy, "Fang Tian Hua Ji" (CTA Strategy), focuses on futures markets, capturing trends regardless of price direction, suitable for markets with significant price movements [33][35][39]. - The fifth strategy, "Taiji Shuang Jian" (Market Neutral), aims to generate absolute returns by hedging market risks, effective in bear and volatile markets but may underperform in bull markets [41][45][48]. - The sixth strategy, "Ruan Wei Jia" (Fixed Income +), combines high-quality bonds with a small allocation to riskier assets, providing stability but vulnerable to rising interest rates [50][53][56]. - The seventh strategy, "Xiu Hua Zhen" (Arbitrage), exploits price discrepancies across markets, generating small but cumulative profits, effective in volatile conditions but reliant on market efficiency [58][61][63]. Group 2: Strategy Suitability - Each strategy is designed for specific market conditions, with subjective long strategies thriving in bullish environments, while quantitative strategies excel in active trading scenarios [15][23]. - Macro hedging strategies are versatile but can falter during extreme market events, while CTA strategies benefit from significant price trends [31][39]. - Market neutral strategies provide a buffer against market downturns, whereas fixed income plus strategies are contingent on interest rate movements [48][56]. - Arbitrage strategies are most effective in volatile markets but depend on the quick correction of price discrepancies [63]. Group 3: Conclusion - The article concludes by encouraging investors to choose strategies that align with their risk preferences, highlighting the importance of understanding each strategy's unique attributes and market applicability [67][69].
