Starting from early 2025, the A-share Free Cash Flow Index officially entered the sight of ETF investors as an innovative strategy. In just over a year, the sector has rapidly expanded, and as of March 31, 2026, there are 30 ETFs tracking cash flow-related indices in the entire market, with a total scale exceeding 45 billion yuan. Entering 2026, in the market environment of physical re-inflation, the attention on free cash flow strategies continues to rise. As investors become increasingly familiar with this concept, their focus has become more detailed: what are the differences between different free cash flow indices? Today, we will focus on three free cash flow targets that select stocks from the entire market — the China Universal CNI Free Cash Flow Index (980092.CNI), the CSI All Share Free Cash Flow Index (932365.CSI), and the FTSE China A-Share Free Cash Flow Focus Index (888888.FI) (hereinafter referred to as China Universal, CSI, and FTSE, respectively), and delve into their differences. **1\. "Stock Selection Code" Unveiled** Free cash flow is the net cash flow available for discretionary use after deducting capital expenditures. This indicator filters out targets with high profit quality and strong cyclical resilience, which can support sustainable dividends through relatively stable cash flow and achieve relatively superior long-term returns through endogenous growth potential. Therefore, free cash flow can serve as a core indicator for measuring a company's true profit quality and value creation capability. Currently, most free cash flow indices in the market primarily use **free cash flow rate (free cash flow/enterprise value)** as the core stock selection indicator, filtering for targets with high "cash flow cost-effectiveness," rather than simply companies with high absolute cash flow. Essentially, it balances the dual logic of high free cash flow and low valuation. The compilation schemes of China Universal, CSI, and FTSE are generally similar: they all exclude financial and real estate industries from the liquid stocks in the A-share market, preferentially selecting targets with higher free cash flow rates, using free cash flow weighting, setting a 10% individual stock weight limit, and conducting quarterly adjustments. The core differences mainly lie in the **negative exclusion** rules: China Universal adds an additional requirement for **ROE stability**, excluding the bottom 10% of companies with ROE fluctuations over the past 12 quarters, while also setting stricter thresholds for the ratio of operating cash flow to operating profit, reflecting **emphasis on profit quality.** CSI places greater emphasis on **cash flow sustainability**, requiring positive operating cash flow for five consecutive years, and when excluding based on profit quality, it divides the indicator's denominator by total assets, thereby imposing stricter constraints on high-debt and high-leverage companies. FTSE integrates **quality, volatility, and growth** across three dimensions, using FTSE's proprietary factor system, which more reflects the stock selection standards for A-share cash flow from a foreign investment perspective. **Table: Comparison of Different Free Cash Flow Index Compilation Schemes** Note: Data comes from the index company's official website, as of March 31, 2026. **II. "Component Portrait" Full Perspective** After clarifying the differences in compilation logic, let's take a direct look at the differences in the holdings of the three indices in terms of industry and market capitalization distribution. **Overall, the three cash flow indices have a relatively balanced coverage in terms of industry and market capitalization scale, with moderate concentration and a market capitalization structure leaning towards mid to large caps.** **Table: Comparison of Market Capitalization Distribution of Different Free Cash Flow Indices** Note: Data comes from Wind, as of March 31, 2026. In terms of industry distribution, the weighted industries of the China Securities Index and the National Securities Index are quite similar, with the top four being automobiles, home appliances, oil and petrochemicals, and transportation. Among them, the automobile industry accounts for about 13.7% in the China Securities Index, making it the largest industry, followed by transportation, oil and petrochemicals, and home appliances, accounting for 12.4%, 9.8%, and 9.1% respectively. The National Securities Index moderately overweights the automobile sector to 19.7% based on a similar industry structure, **with a reasonable combination of cyclical and manufacturing sectors**; the FTSE, affected by growth dimensions, has a higher allocation in home appliances (18.6%) and telecommunications (12.1%), with almost no exposure to oil and petrochemicals. **Figure: Industry Comparison of Different Free Cash Flow Indices** Note: Data comes from Wind, as of March 31, 2026. **III. "Practical Performance" Showdown** After discussing the compilation logic and holdings portrait, we ultimately need to focus on performance as a hard indicator to see how the three indices perform in different market environments. From a long-term perspective, the performance of the National Securities Index and the China Securities Index is highly similar: since 2014, the annualized return of the National Securities Free Cash Flow Index has reached 20.7%, while the China Securities All Share Free Cash Flow Index is at 20.4%, with a Sharpe ratio of 0.90, outperforming the FTSE China A-Shares Free Cash Flow Focus Index's annualized return of 18.6% and a Sharpe ratio of 0.85. **Figure: Performance Comparison of Different Free Cash Flow Indices** Note: Data from Wind, from January 1, 2014, to March 31, 2026, using total return index. Further focusing on the comparison between the National Index and the CSI Index, it can be seen from the annual performance that in a bull market with widespread gains, the aggressiveness of the National Index may be slightly inferior to that of the CSI Index; however, once the market enters a downward adjustment phase, the defensive properties of the National Index become more prominent. This was particularly evident during the three consecutive years of the bear market from 2021 to 2023: the National Index Free Cash Flow achieved positive returns for three consecutive years, demonstrating relatively strong performance resilience. In summary, although the three free cash flow indices for the entire market are generally derived from the same source, each has its own focus: the National Index and the CSI Index are purer value indices, with long-term performance leading over the FTSE Cash Flow Index that incorporates growth factors; specifically, the National Index Free Cash Flow Index, with its stricter profitability stability screening, shows better defensive resilience in a declining market. Since 2026, the market has continued to experience fluctuations and adjustments, with accelerated rotation of hotspots, highlighting the importance of index defensiveness. As of March 31, 2026, the National Index Free Cash Flow Index achieved a year-to-date return of 7.4%, demonstrating an independent performance in a volatile market and showcasing its "winning through stability" allocation value. For investors looking to implement a cash flow strategy and solidify the ballast of their portfolios, it is advisable to pay special attention to the **Free Cash Flow ETF E Fund (code: 159222), which tracks the National Index Free Cash Flow Index, as well as the corresponding feeder funds (Class A: 024566, Class C: 024567)**, utilizing a disciplined true profitability strategy to navigate market fluctuations and capture long-term value ### Related Stocks - [563770.CN](https://longbridge.com/en/quote/563770.CN.md) - [159276.CN](https://longbridge.com/en/quote/159276.CN.md) - [159222.CN](https://longbridge.com/en/quote/159222.CN.md) - [159201.CN](https://longbridge.com/en/quote/159201.CN.md) - [560120.CN](https://longbridge.com/en/quote/560120.CN.md) ## Related News & Research - [SNAP changes in 2026: How stricter rules and rising food prices impact millions of American families](https://longbridge.com/en/news/286801784.md) - [US cyber agency CISA exposed reams of passwords and cloud keys to the open web](https://longbridge.com/en/news/286937105.md) - [Americans Have Spent $41 Billion Extra On Gas Since Iran War Began As Inflation Pressures Spread Across Economy](https://longbridge.com/en/news/286750219.md) - [Nippo Doubles Year-End Dividend After Beating Medium-Term Profit Targets](https://longbridge.com/en/news/287042912.md) - [Asia Distillates-Window activity lackluster; June spot sales remain underway](https://longbridge.com/en/news/287041353.md)
