What Is It / Concept Explanation

An investor looking for all currently available CSI 300 index funds on the market can open our fund screening tool. This tool integrates public mutual fund data (sourced from the Asset Management Association of China and exchange announcements) to display funds in a 'normal subscription' status as required by regulations. 'Available' means the fund is open for subscription, has not suspended sales, and has not been liquidated early. With this tool, you can avoid digging through individual fund company websites and view the latest lists of equity, mixed, bond, money market, index, and QDII funds all in one place.

Principles & Formulas / Algorithm

The screening logic behind the tool is based on three data layers:
1. Fund Status Marker: Exchanges and clearing agencies (CSDC) update the 'available/unavailable for subscription' status daily. The tool only reads records marked as 'available'.
2. Key Metrics Calculation: The '1-Year Return' shown in the list is calculated using the Time-Weighted Return (TWR):
Return = (Ending NAV + Dividends During Period) / Beginning NAV − 1
Annualized Volatility = Standard Deviation of Weekly Returns × √52
3. User Filters: Your selected fund type, company, years since inception, and AUM (Assets Under Management) range are translated into SQL queries to filter matching funds from the database.

Why is this design logical? Using time-weighted returns eliminates the impact of cash inflows and outflows, truly reflecting the fund's management capabilities. Volatility uses weekly data to balance sensitivity and stability. Status markers come from official clearing systems, ensuring the list is genuinely 'buyable'.

How to Use This Tool / Step-by-Step Guide

Click the Fund Type dropdown and select 'Equity'. If you only want passive index funds, select 'Index'.
Type 'E Fund' in the Fund Company input box (supports fuzzy matching; typing the first few letters is enough).
Check the Years Since Inception: Click the 'Over 3 Years' option to filter out newly launched funds.
In the 1-Year Return (%) range boxes, enter 10 on the left and 50 on the right (representing a 10% to 50% return).
Click the 'Search' button. The table below will refresh immediately, displaying all available funds that meet your criteria.
The table includes columns such as Fund Code, Name, Type, 1-Year Return, Maximum Drawdown, and Management Fee. Click any column header to sort the results.

Complete Example / Practical Walkthrough

Let's take 'searching for E Fund equity funds established for over 3 years with an AUM of over 1 billion' as an example.
Open the fund screener above:
• Select Equity from the 'Fund Type' dropdown.
• Enter E Fund in the 'Fund Company' input box.
• Click Over 3 Years under 'Years Since Inception'.
• Enter a minimum value of 10 in the 'AUM (100M)' range box and leave the maximum blank (meaning no upper limit).
• Click 'Search'.
The table will now display about 3 funds (sample data):
Fund code 110011, name 'E Fund Small and Mid Cap Mixed', type Mixed (not strictly differentiated here, just for illustration—actual equity funds have an 80% minimum position limit). 1-Year Return 25.3%, Maximum Drawdown -18.2%, Management Fee 1.50%.
Interpretation: This fund has above-average returns over the past year, but its maximum drawdown is nearly 20%, making it a higher-volatility product. Investors should make decisions based on their own risk tolerance.

More Examples / Multi-Scenario Comparisons

Counter-example: Relaxing criteria leads to too many results. Without changing other conditions, simply change 'Years Since Inception' to 'No Limit' (uncheck the box). The search results increase to 37 funds, including many newly launched funds established less than half a year ago. These funds have a NAV just over 1, and their 1-year return data is incomplete, offering low reference value.
Comparison: Differences in selecting return ranges. Searching for the same 'E Fund equity funds, over 3 years old, AUM over 1 billion', but changing the return range to 0%–5% yields 2 funds (e.g., E Fund Consumer Industry, 1-year return 4.2%). This suggests you might be in a market downturn or the fund's strategy is highly defensive. You can use this tool to quickly compare the distribution of funds across different performance ranges.

How to Interpret Results / Meaning of Values

Key Metric	Interpretation Range	Meaning
1-Year Return	> Category Average + 10%	Outstanding performance; monitor sustainability (check for concentrated holdings)
	Category Average ± 5%	Average level; filter further based on costs
	< Category Average - 10%	Exercise caution; potential style mismatch or management issues
Maximum Drawdown	< -30% (Equity)	High risk; suitable for aggressive investors
	-10% to -30%	Medium risk; most balanced funds fall in this range
	> -10%	Lower volatility, but potential return upside may also be limited
Management Fee	≤ 0.5% / year	Low cost; suitable for passive strategies or long-term holding
	1.0% - 1.5% / year	Industry average for active management
	≥ 2.0% / year	Verify if performance offers excess compensation

The data in the table is based on the CSI fund classification benchmarks. You can click the fund code in the tool to view the complete historical NAV trend to assist your decision-making.

Common Misuses / Pitfalls to Avoid

Only looking at return rankings and ignoring fees: Class A shares might have a 1.5% subscription fee vs. Class C with no subscription fee; for short-term holding, Class C is more cost-effective. The 'Fee' column in the tool's table defaults to Management Fee + Custodian Fee. Click for details to see the actual total cost.
Equating 'Available' with 'Recommended': The list only reflects the subscription status; it does not mean the fund is of high quality or suitable for you. Especially when the fund's AUM is too small (< 100 million), there may be liquidation risks, which the tool does not automatically exclude.
Ignoring the timeliness of NAV accuracy: Return data is generally calculated based on T-1 day NAV, and same-day subscriptions are confirmed at the next day's NAV. Pay attention to the data date labels when using the tool.
Misusing fund type filters: Some funds are nominally 'Mixed' but actually maintain equity positions above 80% long-term. Selecting 'Equity' will miss these funds. It is recommended to look at 'Mixed' first, then judge based on holding ratios.
Available list ≠ Guaranteed purchase: Some funds set daily subscription limits (e.g., a maximum of 10,000 per account daily). The tool cannot display these limits; you need to check the fund announcements.

Frequently Asked Questions (FAQ)

1. Why isn't 'E Fund Blue Chip Selected' in the list when I search for it?

The fund may be in a suspended subscription or limited status. The tool only displays 'Available for Subscription' statuses. After 2021, the E Fund Blue Chip Selected managed by Zhang Kun faced multiple purchase limits, during which it was removed from the list. You can switch to the 'Suspended Subscription' tab in the tool to view historical data (if the tool provides this feature).

2. Does the available fund list include newly launched funds (IPOs)?

Yes. As long as the fund contract takes effect and enters the normal subscription and redemption period, it is considered available. However, funds in their initial offering period (subscription period) are usually not on this list because the fund has not yet been established. We display funds in their offering period separately in the 'New Funds' section.
