Description

Technical Field

[0001] The present invention relates to the field of fund portfolio adjustment technology, and in particular to a fund portfolio adjustment method and system. Background Art

[0002] In fund investment advisory services, portfolio rebalancing is a core component of preserving and increasing the value of client assets, but traditional rebalancing methods suffer from significant flaws. Existing technologies rely on manual grouping and categorizing client holdings. While attempting to group clients holding the same component funds, they overlook the differences in actual holdings within the same group. This can lead to mismatched portfolios and low fund utilization during rebalancing. When managing multiple portfolios or processing a large number of client rebalancing requests, manual operations are not only inefficient but can also lead to idle funds and missed market opportunities due to omissions or delays. System performance also faces bottlenecks when processing large-scale transactions. Furthermore, fund switching and regular subscription and redemption operations must be performed independently, preventing dynamic adaptation. This makes it difficult to balance efficient rebalancing with timely funding in complex scenarios with portfolio deviations. For example, specialized funds such as QDII require rapid rebalancing to respond to exchange rate fluctuations. However, traditional methods, limited by manual intervention and a single model, cannot achieve rapid fund turnover through the intelligent combination of fund switching and subscription and redemption. These problems have resulted in significant deficiencies in the accuracy, efficiency, and market responsiveness of existing portfolio adjustment solutions. There is an urgent need for a solution that can automatically handle multi-mode portfolio adjustments, dynamically match customer needs, and improve capital utilization. Summary of the Invention

For funds from different companies or partially convertible scenarios, a multi-round matching algorithm dynamically matches redemption and rebalancing ratios, ensuring immediate fund connection and preventing idle funds. The hybrid model design further balances efficiency and flexibility. Using preset timeliness weights and risk preference parameters, it simultaneously allocates partial ratios of the same fund to both conversion and redemption paths. This leverages the T+0 arrival advantage of TA conversions to quickly respond to market changes, while also handling complex deviation scenarios through cyclical matching within the redemption and rebalancing queues, maximizing fund utilization. The system's automatically generated rebalancing instructions cover all scenarios, from precise matching to partial matching, and ultimately automatically switching to simulated redemption mode, eliminating manual grouping errors and performance bottlenecks. Compared with the existing technology, the present invention shortens the portfolio adjustment cycle by more than 50% and reduces the idle fund rate to below 5%. Especially in the portfolio adjustment of time-sensitive funds such as QDII, through hybrid mode and dynamic parameter adjustment, it ensures that customers can capture market opportunities while accurately controlling risks and returns, significantly improving the intelligence and competitiveness of investment advisory services. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] For purposes of illustration and not limitation, the present invention will now be described with reference to embodiments thereof and the accompanying drawings, in which: Figure 1 1 is a flow chart of a fund portfolio adjustment method according to an embodiment of the present invention; Figure 2 Schematic diagram of the structure of the fund portfolio adjustment system in an embodiment of the present invention; Figure 3 Schematic diagram of the structure of an electronic device in an embodiment of the present invention. DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0016] It should be noted that, in the absence of conflict, the embodiments of the present application and the features thereof can be combined with each other. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0017] refer to Figure 1 This embodiment discloses a fund portfolio adjustment method, comprising the following steps: S100: Perform a difference analysis on the current fund holdings and the target fund holdings of the fund investment advisory portfolio, and the difference analysis results include the funds that need to be adjusted and the adjustment ratio.

[0018] Before conducting a discrepancy analysis, obtain current and target fund holdings data from the fund custody system or portfolio management platform. Data fields include fund name, fund company identifier, and holding ratio. Fund-related data is aligned by fund name or unique code to ensure a one-to-one correspondence between the current holdings and the target fund list. If there are new funds added to the target holdings or funds removed from the current holdings, they are automatically marked as requiring full subscription or redemption. Furthermore, based on the fund company identifier, each fund in the current holdings is compared against the target holdings. Fund pairs with the same fund company are selected and converted. For example, if Fund A (Fund Company X) in the current holdings and Fund B (Fund Company X) in the target holdings belong to the same company, they are marked as convertible. The remaining funds in the current holdings and the target holdings are not marked or can be marked as non-convertible.

[0019] Difference analysis is the calculation of holding differences, and the results include redemption ratios and subscription ratios. When the difference between the current fund holding ratio and the target fund holding ratio is positive, the result is the redemption ratio, meaning the current fund needs to redeem that ratio. When the difference between the target fund holding ratio and the current fund holding ratio is positive, the result is the subscription ratio, meaning the target fund needs to subscribe to that ratio. For example, if the current Fund A holding ratio is 30% and the target position is 20%, the redemption ratio is 10%; if the current Fund B holding ratio is 15% and the target position is 25%, the subscription ratio is 10%. For the above-mentioned convertible fund pair, that is, the current holding Fund A and the target holding Fund B belong to the same fund company, then if the difference between the current Fund A holding ratio and the target Fund B holding ratio is positive, the difference is the redemption ratio; otherwise, it is the subscription ratio.

[0020] The above-mentioned redemption ratio is classified into the redemption queue, and the application ratio is classified into the application queue.

[0021] S200: Based on the results of the difference analysis, pattern matching is performed on the portfolio adjustment ratio. The patterns include fund conversion pattern, simulated subscription and redemption pattern, and mixed pattern.

[0022] Based on the difference analysis results in step S100, according to the matching relationship of the fund companies corresponding to the funds that need to be adjusted, fully convertible fund pairs, fully non-convertible fund pairs and partially convertible fund pairs are screened out. The adjustment ratio of the fully convertible fund pairs is marked as the fund conversion mode. In this embodiment, the fund conversion mode is TA conversion; the adjustment ratio of the fully non-convertible fund pairs is marked as the simulated subscription and redemption mode; the adjustment ratio of the partially convertible fund pairs is marked as the mixed mode. Fund conversion mode: based on the conversion relationship between the current fund holdings and the fund company of the target fund holdings, the adjustment ratio of the convertible fund is directly converted into shares; simulated subscription and redemption mode: the redemption ratio is dynamically matched with the adjustment ratio through multiple rounds of matching algorithms, and subscription and redemption instructions are generated to achieve instant subscription and redemption; mixed mode: the allocation ratio is calculated for the current fund holdings, and based on the allocation ratio, part of the ratio is simultaneously allocated to the fund conversion mode and part of the ratio to the simulated subscription and redemption mode to complete the direct share conversion and instant subscription and redemption of the fund holdings.

[0023] For the fund conversion mode, based on the difference analysis results, the marked convertible fund pairs are obtained, and the conversion threshold value of the fund pairs is calculated. and Fund The conversion priority parameter , wherein the conversion threshold is calculated based on historical data, and the calculation formula is: ,in is the historical average holding deviation, which, for example, represents the average holding deviation of the fund in the past 30 days; is the standard deviation, which means the position deviation The standard deviation of is a tolerance parameter, which is set manually; the conversion priority parameter ,in, For the Fund liquidity, For the The switching cost of the fund, It is the liquidity weight coefficient, which is set according to the liquidity and conversion cost of the fund.

[0024] Based on the conversion priority parameter rank the conversion priorities of the fund pairs; According to the fund pair, matching conversion is performed, and the matching conversion rules include exact matching, partial matching and termination conversion, wherein, Exact matching can be performed by: If the absolute difference between the current fund holding ratio and the target fund holding ratio , and the target fund has no holdings, a one-to-one share conversion instruction is generated, where Funds currently held The holding ratio, Funds in target holdings holding ratio; for example, if the current holding ratio of Fund A of the same fund company is 20%, the target holding ratio of Fund B is 20%, and the user has no target holding fund, a 20% share conversion instruction will be generated.

[0025] Partial matching can be performed by: like , then the conversion ratio is determined to be , based on the conversion priority order, the conversion ratio is determined and calculated. and The difference is the remaining proportion, and the remaining proportion is transferred to the ordinary redemption queue. In this embodiment, the ordinary redemption queue is a simulated redemption mode, which does not participate in the execution of the fund conversion mode.

[0026] Terminate conversion: If , the fund conversion will be terminated and the fund manager will be notified.

[0027] The technical solution of this step effectively avoids the error caused by manual judgment of whether the position deviation is convertible. and and tolerance Quantify acceptable deviations. For example, the conversion threshold T of the current holding fund A and the target holding fund B is 0.53%. If the current deviation from the target is 0.3%, an exact match is performed. If the deviation is 1.5%, the conversion is terminated directly. By introducing the priority parameter , funds with high liquidity and low conversion costs can be given priority to maximize capital efficiency.

[0028] For the simulated redemption mode, generating a redemption instruction to achieve instant redemption includes the following steps: S1: Based on the difference analysis results, obtain the redemption ratio and subscription ratio in the redemption queue and subscription queue, and adjust the redemption ratio and subscription ratio of the funds in the redemption queue and subscription queue based on the preset weight parameters. and Calculation Fund The weighted ratio : ,in, For the Fund The redemption ratio, For the Fund The application ratio, is the preset market volatility dynamic weight, For the Fund It should be noted that the same fund can only have a redemption ratio or an application ratio. When calculating the weighted ratio, if one of them exists, the other one is 0.

[0029] For example, the redemption queue includes Fund A: RA = 22%, Fund B: RB = 10%, and the subscription queue includes Fund C: SC = 10.49%, and Fund D: SD = 55%. Fund A's weighted ratio WA = (22%)·(1+0.8·0.5) = 22%·1.4 = 30.8%; Fund C's weighted ratio WC = (10.49%)·(1+0.8·1.0) = 10.49%·1.8 ≈ 18.9%.

[0030] After calculating the weighted ratio of each fund, Sort the funds in the redemption queue and subscription queue from high to low. For example, Fund A (WA=30.8%) ranks first in the redemption queue, and Fund C (WC=18.9%) ranks first in the subscription queue.

[0031] S2: weighted ratio Sort from largest to smallest and select the fund with the largest weighted proportion in the redemption queue and subscription queue respectively; S3: If the redemption ratio of the fund corresponding to the largest weighted ratio in the redemption queue Greater than the adjustment ratio of the fund corresponding to the largest weighted ratio in the subscription queue , then set the pairing ratio to , and generate a redemption instruction, the redemption instruction is: redeem The redemption instructions are: redeem 10.49% of Fund A and subscribe to 10.49% of Fund C. At this point, the remaining redemption ratio of Fund A is 11.51%, and this remaining redemption ratio is re-entered into the redemption queue. The SC of Fund C in the subscription queue has been fully matched and is removed from the queue.

[0032] S4: If the adjustment ratio of the fund corresponding to the largest weighted ratio in the subscription queue Greater than the redemption ratio of the fund corresponding to the largest weighted ratio in the redemption queue , then set the pairing ratio to , and generate a redemption instruction, the redemption instruction is: redeem ratio, and subscribe to the target fund with the corresponding ratio.

[0033] S5: Loop through steps S1-S3, recalculating each step And sort until consecutive Wheel pairing efficiency , then the pairing is terminated, where is the preset threshold, ,in, is the sum of the pairing ratios of all fund pairs in this round of pairing, The total ratio of the redemption queue to the subscription queue at the beginning of this round. When the matching is terminated, if there is an unmatched redemption ratio, the funds will be transferred to the subscription queue of other funds with similar yields. If there is an unmatched subscription ratio, the funds will be transferred to the subscription queue of the money market fund.

[0034] S6: After the pairing is terminated, the subscription and redemption instructions generated in each round of pairing are merged, and it is ensured that each redemption instruction corresponds to a subscription instruction to achieve instant subscription and redemption.

[0035] For example, in round 1, the order is: redeem 10.49% of Fund A and subscribe for 10.49% of Fund C; Second round of instructions: redeem 5% of Fund B and subscribe for 5% of Fund D; Merged instructions: All redemption and subscription instructions are sorted by generation time and submitted to the fund trading system.

[0036] For hybrid mode allocation, this embodiment implements the dynamic allocation ratio calculation of the hybrid mode through the following steps, combining the time weight and risk preference parameters to balance the execution efficiency of fund conversion and simulated subscription and redemption modes: Obtain marked convertible fund pairs from the difference analysis results, that is, screen out the convertible fund pairs where each fund held by the current fund and the target fund belong to the same fund company; Initialize the time-sensitive weight parameters , risk preference parameters and balance coefficient For the parameters here, the timeliness weight refers to the redemption time of the fund. For example, if a fund is redeemed 3 days later, then ; Risk preference parameters Set according to the customer's risk level, for example, the risk preference parameter for conservative customers is 0.8, and the risk preference parameter for aggressive customers is 0.2; the balance coefficient The priority for balancing timeliness and risk is set to 0.6 in this embodiment. For the dynamic adjustment of the above-mentioned multiple parameters, the weight parameter is dynamically adjusted according to market conditions. and risk appetite parameters Specifically, when market volatility is high, increase To increase , speed up capital turnover; for risk-averse customers, increase To reduce , reducing conversion risks.

[0037] Based on preset time weight parameters and risk appetite parameters Calculate the blend ratio for each fund : ; Based on the mixing ratio Calculate the conversion ratio based on the rebalancing ratio of the convertible fund pair The conversion ratio includes the fund conversion mode ratio and the imitation subscription and redemption mode ratio, wherein the fund conversion mode ratio is: ; Imitation subscription and redemption model ratio: ; Execute the fund conversion mode position adjustment for the fund conversion mode ratio; Execute the imitation subscription and redemption mode position adjustment for the imitation subscription and redemption mode ratio. For example, the current holding ratio of fund A is 30%, and the holding ratio of target fund B is 20%. Then the current conversion ratio is is 10%, that is, 10% of Fund A needs to be redeemed. If the result is 0.2, 2% will be allocated to the target fund through the fund switching model, and the remaining 8% will be converted through the simulated subscription and redemption model. During the implementation of the hybrid model, the execution effect must be monitored. If the actual execution rate of the fund switching model is lower than the theoretical value, for example, only 1.5% of the 2% conversion target is completed, the remaining 0.5% will be automatically transferred to the simulated subscription and redemption model for completion.

[0038] The hybrid allocation model addresses the inability of a single model to balance efficiency and timeliness. For example, while QDII funds require several days to arrive due to cross-border transactions, a portion can be transferred to the account on a T+0 basis through a fund conversion model, while the remaining portion is gradually processed through a simulated subscription and redemption model, avoiding reliance on an inefficient model. This hybrid allocation model has reduced the overall cycle time by 50%.

[0039] S300: Automatically generate a position adjustment instruction based on the pattern matching result, wherein the allocation ratio of the mixed mode is dynamically adjusted based on the preset time weight and risk preference parameters.

[0040] S400: During the execution phase of the position adjustment instruction, the transaction status is monitored in real time. If the position adjustment fails due to the following reasons, the position adjustment ratio of the corresponding fund pair will be marked as unfinished. : User reasons: insufficient account funds, position limit, frozen trading permissions; Fund reasons: target fund subscription and redemption suspension, quota sold out, conversion restrictions; System reasons: TA system failure, API interface abnormality; Screen candidate funds from the tradable target fund library: based on a preset yield similarity threshold , select from the tradable target fund library the funds whose yield difference with the original target fund is less than Funds to form a list of candidate funds; The proportion of the position will be adjusted according to the remaining capacity and liquidity of the candidate fund. Allocate to the candidate fund with the closest yield; if the remaining capacity of a candidate fund is greater than the rebalancing ratio , then directly allocate to that fund; if the capacity is insufficient, it will be allocated to multiple candidate funds in proportion to the capacity. For example, if the remaining capacity of candidate fund A is 10% and the remaining capacity of candidate fund B is 8%, D×(10% / 18%) will be allocated to fund A in proportion, and the rest will be allocated to fund B.

[0041] If all candidate funds cannot accommodate the rebalancing ratio If there is no eligible candidate fund, the proportion of Allocate to money market funds to ensure that the return on funds is no lower than the preset benchmark.

[0042] Generate a new reposition instruction. If it is successfully allocated to the candidate fund, generate the instructions of "redeem the original fund reposition ratio D" and "subscribe to the alternative fund ratio D"; otherwise generate the instructions of "redeem the original fund ratio D" and "subscribe to the money market fund ratio D".

[0043] It can be seen that S400 addresses the technical problem that traditional fund rebalancing methods cannot automatically handle rebalancing failures due to user or market anomalies (such as account restrictions, fund subscription and redemption suspensions), resulting in idle funds or loss of returns. By establishing an alternative fund screening mechanism based on yield similarity thresholds and a money market fund guarantee strategy, it achieves automated fault handling when rebalancing fails. That is, the system first screens candidate funds from the tradable fund library whose yield difference from the original target fund is within a preset threshold, and allocates them according to their capacity and liquidity. If it still cannot be completed, the remaining proportion will be forcibly transferred to the money market fund to ensure that the funds are always in an effective operating state, avoiding rebalancing interruptions or loss of returns due to anomalies of a single fund, thereby significantly improving the robustness and fund utilization of the rebalancing system. At the same time, the return benchmark of customer assets is maintained through dynamic replacement strategies, solving the defects of traditional methods that rely on manual intervention, have low processing efficiency and cannot guarantee fund returns.

[0044] To sum up, the fund portfolio adjustment method of this embodiment addresses the technical problems of low efficiency, insufficient capital utilization, inability to respond to market changes in a timely manner, and performance bottlenecks when handling multiple portfolios or a large number of customers in traditional manual adjustment. By constructing an intelligent adjustment method that is compatible with fund conversion and simulated subscription and redemption, it achieves the coordination of difference analysis, dynamic pattern matching and multi-round matching algorithms. First, by comparing current and target holdings, convertible fund pairs are screened based on fund company matching, and redemption and application queues with adjustment ratios are calculated. Second, a multi-mode matching strategy, comprising fund conversion, simulated application and redemption, and hybrid modes, is adopted to address the compatibility requirements of rapid conversion of funds within the same company and flexible adjustment of funds across companies. At the same time, adaptive termination conditions and exception handling mechanisms are introduced (based on yield similarity to screen alternative funds or money market funds as a backup) to ensure fund utilization and return benchmarks in the event of failed adjustments. Through parameterized control (such as conversion thresholds, weighting ratios, and hybrid ratio β) and automated instruction generation, manual grouping errors are eliminated, the adjustment cycle is shortened to minutes, and the idle fund rate is reduced to below 5%. In the adjustment of special funds such as QDII, timeliness is improved through a dual path of fund conversion and multiple rounds of matching. Ultimately, the accuracy, efficiency, and market responsiveness of adjustments are comprehensively improved, manual omissions and performance bottlenecks are significantly reduced, and the adjustment needs of large-scale customers are supported while maximizing fund utilization and return capture capabilities.
