Fig. 1 is the flow chart of the fund rebalancing judgment method in one embodiment of the invention, as shown in Figure 1, a kind of base
Golden rebalancing judgment method, comprising the following steps:
Step S1, preset configuration file: preset configuration file, configuration file include in the database of fund transaction system
Have to the preset time threshold of single fund, weight threshold and judges type.
For investor, the risk for only investing single fund is larger, therefore judgement rebalancing object of the invention is fund
Combination, rather than single fund, therefore the fund transaction system in this step can be and can carry out in any prior art
A plurality of types of funds, the system traded such as currency class, equity class, bond class fund.In fund transaction system, in advance in number
According to configuration file is arranged in library, all single funds that can be bought and sold in fund transaction system are configured, respectively preset time
Threshold value, weight threshold and judge type.
It is to buy in start to needing rebalancing in fund combination specifically, time threshold is set as a fixed duration value
Preset time is poor, is arranged as unit of one day.The weight threshold present weight that is single fund in fund combination and when buying in
Default weight is poor.Judge that type includes long type when being judged as the fixation of foundation with duration, the weight for being judged as with weight foundation
The composite type that long type and weight threshold type successively judge when threshold type, fixation.The setting of configuration file can use
It is as shown in table 1 below:
Table 1
Step S2 calculates weight: when the combination of generation fund is bought in fund transaction system, record fund combination is bought in
Time calls the weight calculation script that is preset in fund transaction system, calculates single fund in fund combination when buying in
Initial weight, and timing daily calculate the present weight of single fund in fund combination.
In fund transaction system, weight calculation script is set in the database in advance, and weight calculation script is for calculating
The present weight of single fund in initial weight of the single fund when buying in, the fund combination bought in.Weight calculation script
Calculation method when calculating weight is as follows: it is always golden that initial weight=single fund when single fund is bought in buys in amount of money ÷
Volume, the present weight of single fund=(the buying in the amount of money+single fund day income of single fund) ÷ always hold position the amount of money.
Therefore when the combination of generation fund is bought in fund transaction system, the total amount in fund transaction system is also obtained
Buy in the amount of money with single fund, it is subsequent daily, go back single fund in timing acquisition fund transaction system day income, base
The amount of money of always holding position of gold combination., can periodically sometime when calculating the present weight of single fund daily in this step, it can
To be a certain moment after 3 point in the afternoon fund day of trade, as 3 points of timings in 30 minutes every afternoon calculate in fund combination
The present weight of single fund.
Step S3 judges whether to need rebalancing: the single fund in fund combination judged whether to need rebalancing,
The single corresponding judgement type of fund judges single fund from when buying according to type is judged in the preceding reading configuration file of judgement
Between to current time time difference whether arrival time threshold value, or initial weight when buying in present weight weight difference whether
Weight threshold is reached, if reaching, exports TRUE signal, otherwise exports FALSE signal.
It, can be after periodically calculating single fund present weight daily, successively to single in fund combination in this step
Fund judged one by one, judge sequence can be according to fund combine in after single fund buys in the sequencing sequence of time
Judgement is also possible to carry out judging after how much stroke waits sequence to single fund name, can also be and mention to single fund name
Judge after taking first letter of pinyin to sort.It is first corresponding in reading configuration file to sentence before judging whether to need the judgement of rebalancing
Any class when disconnected type belongs to fixed in long type, weight threshold type or composite type, then according to judge that type selects to be
Using time threshold judgement or weight threshold judgement, judging result is finally obtained.Judgement side when judgement is fixed when long type
Method are as follows: the single fund of the current time-of single fund buy in the time whether arrival time threshold value.When judging weight threshold type
Judgment method are as follows: whether initial weight when the single fund of the present weight-of single fund is bought in reaches weight threshold.Judgement
When composite type, then successively long type and weight threshold type when fixing are judged.The TRUE signal that finally exports or
FALSE signal is for giving other models corresponding trigger signal.
The present embodiment carries out time and weight threshold to the single fund in fund combination after preset configuration file
Dual judgement, it is determined whether rebalancing.The mode of above-mentioned judgement rebalancing can combine Vehicles Collected from Market to fluctuate in real time, optimize fund
Combination carries out organic adjustment to fund combination, realizes the maximization of investment return.
In one embodiment, after weight calculation script is called, calculate in the following way: weight calculation script is from base
Obtained in golden transaction system fund combination when buying in buy in the time, total amount, single fund buy in the amount of money, single fund is bought
The calculation of fashionable initial weight are as follows: initial weight when single fund is bought in be equal to single fund buy in the amount of money divided by
Total amount；Weight calculation script obtained from fund transaction system single fund day income, fund combination the amount of money of always holding position,
The calculation of single fund present weight are as follows: the amount of money of buying in that single fund present weight is equal to single fund adds single base
Day the sum of the income of gold, divided by the amount of money of always holding position.
In fund transaction system when fund combination is bought in, will record fund combination when buying in buy in the time, total amount,
Single fund buys in the amount of money, therefore when calculating initial weight, weight calculation script is available from fund transaction system
Calculation to these information, initial weight when single fund is bought in is as follows:
Initial weight=single fund when single fund is bought in buys in amount of money ÷ total amount；
In fund transaction system, daily fund transaction after, will record the same day single fund day income, fund
The amount of money of always holding position of combination, therefore when calculating present weight, weight calculation script from fund transaction system it is available to
The calculation of these information, single fund present weight is as follows:
The present weight of single fund=(the buying in the amount of money+single fund day income of single fund) ÷ always holds position gold
Volume.
The present embodiment specifies calculation used by weight calculation script, available by above-mentioned calculation
Original number used by initial weight and present weight when single fund is bought in fund combination, especially present weight calculate
According to being daily real-time fund data, the status of current single fund can be accurately determined, provide the number of confirmation for subsequent judgement
According to foundation.
In one embodiment, as shown in Fig. 2, according to type is judged, when judging single fund, using following judgement side
Method:
Judge single fund judges long type when whether type is fixed, buys in if so, judging that current time subtracts
Time whether arrival time threshold value, if reach if export TRUE signal, otherwise export FALSE signal, the judgement class of single fund
Long type when whether type is fixed, if it is not, then entering the judgement of weight threshold type；
Judge single fund judges whether type is weight threshold type, if so, judging the current power of single fund
It subtracts whether weight when buying in reaches weight threshold again, if reaching, exports TRUE signal, otherwise export FALSE signal；It is single
A fund judges whether type is weight threshold type, if it is not, then entering the judgement of composite type；
Judge single fund judges whether type is composite type, if so, judging that current time subtracts buys in the time
Whether arrival time threshold value, TRUE signal is exported if reaching, if it is not, continuing to judge that the present weight of single fund subtracts to buy
Whether fashionable weight reaches weight threshold, if reaching, exports TRUE signal, otherwise exports FALSE signal, single fund
Judge whether type is composite type, if it is not, then exporting FALSE signal.
It is solid when entering into unused judgment method first by judging the judgement type of single fund when judging
In timing long type judgment method, then need to judge that current time-buys in whether the time reaches time threshold and then export correspondence
Signal.When entering in weight threshold type judgment method, then need to judge through the calculated present weight-of weight calculation script
Whether initial weight reaches weight threshold and then exports to induction signal.When entering in composite type judgment method, then need successively
Judge that current time-is bought in after whether the time reaches time threshold, whether present weight-initial weight reaches weight threshold, into
And it exports to induction signal.If exporting TRUE signal, then it is assumed that it needs to carry out rebalancing measure, if output FALSE signal,
Think without carrying out rebalancing measure.
The present embodiment carries out the judgement of various ways by above-mentioned the case where being directed to different single funds, can be according to base
The golden market status judges fund combination, judges whether to need rebalancing measure.
In one embodiment, when exporting FALSE signal, then the single fund in fund combination is sentenced into next day
It is disconnected whether to need rebalancing.
When all single funds determine in combining to fund, when the signal of output is FALSE signal, then recognize
For weight calculation script timing in next day without carrying out rebalancing measure, can be waited to calculate single base in fund combination at this time
Then the present weight of gold recycles and judges whether to need rebalancing to the single fund in fund combination.
In one embodiment, also contain in configuration file to the preset rebalancing mode of each fund, as output TRUE
When signal, it is believed that fund combination needs to be implemented weight and restores rebalancing, will according to rebalancing mode corresponding in configuration file
TRUE signal is exported to corresponding rebalancing model.Rebalancing mode include need to recalculate the rebalancing mode of weight, and
Without calculating the rebalancing mode of weight；The corresponding rebalancing model of rebalancing mode for needing to recalculate weight is mean value side
Differential mode type, with the initial weight for recalculating the fund combination；Rebalancing mode without calculating weight is corresponding again
Balance model is fund tune storehouse model, to readjust the weight of single fund in the fund combination.
In the database of fund transaction system when preset configuration file, in addition in such as table 1 to single fund preset time
Threshold value, weight threshold and judge to have preset rebalancing mode outside type, according to rebalancing mode, TRUE signal is exported to correspondence
Rebalancing model.At this point, the setting of configuration file can be using as shown in table 2 below:
| Single fund name | Time threshold | Weight threshold | Judge type | Rebalancing mode |
| A fund | 1 day | 5% | Long type when fixed | It needs to recalculate weight |
| B fund | 3 days | 10% | Weight threshold type | Without calculating weight |
| C fund | 5 days | 20% | Composite type | It needs to recalculate weight |
| D fund | 2 days | 10% | Long type when fixed | Without calculating weight |
Table 2
Mean shift mode is a kind of model for needing to recalculate weight, mean shift mode be by
The Risk Model that H.M.Markowitz (Harry's Markovitz) is proposed in nineteen fifty-two.Markovitz is defined as risk
The method of mathematical statistics is applied in the research of Portfolio Selection Based by the stability bandwidth of expected rate, and mean shift mode makes
The target mutually restricted can reach optimal counterbalance effect.Investor invests a given fund in the regular period
Before, knack, which is ordered, buys how which fund and fund distribute on these funds, and investor needs in the beginning from all possibility
Fund combination in the optimal fund combination of selection one, there are two decision objectives: as high as possible earning rate and as far as possible
Low uncertain risk, best target should be that the target for restricting the two mutually reaches optimum balance.Thus it sets up
The investment model come is mean shift mode, and the circular of mean shift mode is as follows:
Objective function: 2 (r of min бp)=∑ ∑ xixjCov(ri-rj)
rp=∑ xiri
Restrictive condition: 1=∑ xi(permit short sale)
Or 1=∑ xi xi> >=0 (no short sale)
Wherein rpFor fund portfolio yields, riFor the income of i-th fund, xi、xjFor the ratio between investments of fund i, j, that is, weigh
Weight, 2 (r of бp) it is portfolio investment variance (combination overall risk), Cov (ri、rj) it is covariance between two funds.In limitation item
X is solved under parti, make 2 (r of fund constitution's risk бp) minimum, it can be acquired by Lagrangian objective function.
Fund tune storehouse model is a kind of model without recalculating weight, and fund tune storehouse model only carries out in fund combination
Tune storehouse between single fund, and weight is transferred to target weight, target weight=initial weight when single fund is bought in+is matched
Set corresponding weight threshold in file.
The present embodiment, after to output TRUE signal, it is believed that fund combination needs to be implemented the side that weight restores rebalancing
Formula is further judged, by the selection of two kinds of different rebalancing strategies, can not only be led to all funds in fund combination
It crosses the pool that mean shift mode carries out again and adjusts weight, fund tune storehouse can also be passed through to the single fund in fund combination
Model progress is separately adjustable, to realize final maximum revenue.
In one embodiment it is proposed that a kind of fund rebalancing judges system, as shown in figure 3, including such as lower unit:
Configuration unit contains in configuration file to list for the preset configuration file in the database of fund transaction system
The preset time threshold of a fund, weight threshold and judge type；
Computing unit, when being bought in for fund combination to occur in fund transaction system, when buying in of record fund combination
Between, the weight calculation script being preset in fund transaction system is called, it is first when buying in calculate single fund in fund combination
Beginning weight, and timing daily calculate the present weight of single fund in fund combination；
Judging unit judges whether to need rebalancing, reads and match before judgement for the single fund in combining fund
It sets the corresponding judgement type of single fund in file and judges single fund from the time is bought in current time according to type is judged
Time difference whether reach the time threshold, or whether the weight difference of initial weight to present weight when buying in reaches weight
Threshold value exports TRUE signal if reaching, and otherwise exports FALSE signal.
In one embodiment, as shown in figure 4, judging unit includes following module:
Fixed duration type judging module, for judging long type when judging whether type is fixed of single fund, if
Be then judge current time subtract buy in the time whether arrival time threshold value, if reach if export TRUE signal, otherwise export
FALSE signal, single fund judge long type when whether type is fixed, if it is not, then entering weight threshold type judges mould
Block；
Weight threshold type judging module judges whether type is weight threshold type for judge single fund, if
It is whether the weight for then judging that the present weight of single fund subtracts when buying in reaches weight threshold, if reaching, exports TRUE
Otherwise signal exports FALSE signal；Single fund judges whether type is weight threshold type, if it is not, then entering composite class
Type judgment module；
Composite type judgment module judges whether type is composite type for judge single fund, if so, judgement
Current time subtract buy in the time whether arrival time threshold value, TRUE signal is exported if reaching, if it is not, it is single to continue judgement
The present weight of fund subtracts whether weight when buying in reaches weight threshold, if reaching, exports TRUE signal, otherwise exports
FALSE signal, single fund judges whether type is composite type, if it is not, then exporting FALSE signal.
In one embodiment it is proposed that a kind of computer equipment, including memory and processor, it is stored in memory
Computer-readable instruction, when computer-readable instruction is executed by processor, so that reality when processor executes computer-readable instruction
Existing following steps: the preset configuration file in the database of fund transaction system, configuration file are interior containing default to single fund
