Description

债券指数编制方法、装置及计算机可读存储介质
本申请基于巴黎公约申明享有2018年05月16日递交的申请号为2018104699719、名称为“债券指数编制方法、装置及计算机可读存储介质”的中国专利申请的优先权,该中国专利申请的整体内容以参考的方式结合在本申请中。
技术领域
本申请涉及数据处理技术领域,尤其涉及一种债券指数编制方法、装置及计算机可读存储介质。
背景技术
交易所交易基金(Exchange-Traded Funds),简称ETF,是一种在交易所上市交易的、基金份额可变的一种开放式基金。ETF按标的资产不同,分为股票ETF,债券ETF等,目前国内市场上,股票ETF较多,债券ETF存在着巨大的空白,而且现有的债券ETF基本是国债为主的债券ETF,信用债ETF非常匮乏,因此,市场上为了推动债券ETF研发,填补市场空白,开发信用债ETF就有了现实的需求。
若要构建针对信用债的债券ETF,就需要编制该信用债的债券指数,但是由于目前的市场上的债券ETF的构建方案主要是针对国债设计的,其指数编制方案也是适用于国债的,并不适用于信用债,因此,目前亟需能够适用于信用债的债券指数编制方案。
发明内容
本申请提供一种债券指数编制方法、装置及计算机可读存储介质,其主要目的在于解决现有技术中没有适用于信用债的债券指数编制方案的技术问题。

获取全部成分券在前一个交易日的总市值,以及前一个交易日的债券指数的数值;
获取全部成分券在当前交易日的总市值;
根据获取的全部成分券在当前交易日的总市值、全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第一指数计算规则计算当前交易日的债券指数。
此外,为实现上述目的,本申请还提供一种计算机可读存储介质,所述计算机可读存储介质上存储有债券指数编制程序,所述债券指数编制程序可被一个或者多个处理器执行,以实现如上的债券指数编制方法的步骤。
本申请提出的债券指数编制方法、装置及计算机可读存储介质,确定目标交易所的债券指数的成分券,成分券是从该目标交易所的所有上市债券中筛选出的符合预设筛选条件的债券;获取全部成分券在前一个交易日的总市值,以及前一个交易日的债券指数的数值;获取全部成分券在当前交易日的总市值;根据获取的全部成分券在当前交易日的总市值、全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第一指数计算规则计算当前交易日的债券指数。本申请中将符合预设筛选条件的债券作为债券指数的成分券,并根据交易日里的成分券的市值预设的指数计算规则计算当前交易日的债券指数,实现了针对信用债的债券指数计算方案。

本申请目的的实现、功能特点及优点将结合实施例,参照附图做进一步说明。
具体实施方式
应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
本申请提供一种债券指数编制方法。参照图1所示,为本申请一实施例提供的债券指数编制方法的流程示意图。该方法可以由一个装置执行,该装置可以由软件和/或硬件实现。
在本实施例中,债券指数编制方法包括:
步骤S10,确定目标交易所的债券指数的成分券,其中,所述成分券是从所述目标交易所的所有上市债券中筛选出的符合预设筛选条件的债券。
信用债是指政府之外的主体发行的、约定了确定的本息偿付现金流的债券。例如企业债就是一种信用债。以下以上海证券交易所作为目标交易所,对本申请实施例的方案进行说明。
确定截止日期,从目标交易所在该截止日期之前的所有上市债券中筛选出符合预设筛选条件的债券,作为该交易所的债券指数的成分券。以上海证券交易所为例,以下简称上交所,统计其在2018年3月28日之前上市的所有债券,从中筛选出符合预设筛选条件的多个债券作为证券指数的成分券。在一些实施例中,预设筛选条件中的筛选指标主要包括剩余期限、主体评级和信用评级、发行规模。预设筛选条件为:剩余期限在预设时长以上,主体评级和信用评级均在预设级别以上,发行规模在预设数量以上的上交所上市公司债债券。当上市债券同时满足以上条件时,判定该上市债券满足所述预设筛选条件。其中,剩余期限是指债券距离到期剩余的时长。
上述预设时长、预设级别以及预设数量的选择可以根据交易所的上市债券的实际情况进行合理设置。优选地,在一实施例中,预设时长为1年,预设数量为20亿,预设级别为AA级。关于发行规模,基于债券规模越大,资 产配置容量越高的逻辑,指数的标的选在债券发行规模20亿以上,为后期的债券ETF复制提供了现实的操作空间。此外,关于预设级别的设置,市场上现存的一些指数,其主体评级和信用评级设置的门槛较低,基本上涵盖了所有投资级以上的公司债债券,这样的指数作为一个代表公式债整体的指数是无可厚非的,但是作为债券ETF的跟踪标的则是不合适的。而且市场上现存的一些指数没有考虑剩余期限的问题,这对于债券ETF的跟踪标的也是不合适的,因为如果复制的债券的成分券的剩余期限过短,基金会面临频繁调仓的问题,导致面临补券风险,造成交易成本增加,影响整个基金的收益水平。
例如,以上海证券交易所作为目标交易所,从其对应的数据库获取上交所的每只上市债券对应的各个筛选指标的数据,截止到2018年3月28日的数据,上交所未到期的公司债债券共有1535只,按照上述条件能够筛选出符合条件的成分券有400只。
步骤S20,获取全部成分券在前一个交易日的总市值,以及前一个交易日的债券指数的数值。
步骤S30,获取全部成分券在当前交易日的总市值。
步骤S40,根据获取的全部成分券在当前交易日的总市值、全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第一指数计算规则计算当前交易日的债券指数。
在确定成分券之后,根据成分券的市值计算目标交易日的债券指数,在本实施例中采用的第一指数计算规则是利用成分券在当前交易日的前一个交易日的总市值、前一个交易日的债券指数的数值以及在全部成分券在当前交易日的总市值来计算当前交易日的债券指数的数值。由于对于第一个交易日来说,其指数是确定的,即该指数在第一个交易日的初始值为100。在每个交易日结束后,可以获取到成分券的总市值,因此,就可以计算得到第二个交易日的债券指数的数值,以此类推,可以计算得到或许每一个交易日的债券指数的数值。
其中,第一指数计算规则是通过交易日里的每个成分券的收盘价数据以及成分券上市首日的发行规模数据设计的,可以表示为如下公式:
Figure PCTCN2018102134-appb-000001
其中,index T+1为当前交易日T+1的债券指数,index T为当前交易日的 前一个交易日T的债券指数,∑P i T+1Q i为全部成分券在当前交易日的总市值,∑P i TQ i为全部成分券在前一个交易日的总市值。
上述公式中,P i T+1为T+1交易日的债券i的收盘价,Q i为发行规模,所有债券在一个交易日结束后的收盘价与发行规模的乘积之和为总市值。T交易日的总市值的计算方式同理。
本实施例提出的债券指数编制方法,确定目标交易所的债券指数的成分券,成分券是从该目标交易所的所有上市债券中筛选出的符合预设筛选条件的债券;获取全部成分券在前一个交易日的总市值,以及前一个交易日的债券指数的数值;获取全部成分券在当前交易日的总市值;根据获取的全部成分券在当前交易日的总市值、全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第一指数计算规则计算当前交易日的债券指数。本申请中将符合预设筛选条件的债券作为债券指数的成分券,并根据交易日里的成分券的市值预设的指数计算规则计算当前交易日的债券指数,实现了针对信用债的债券指数计算方案。
进一步地,由于随着时间的推移,指数的成分券会不断扩容,即成分券的数量会不断增加,这就意味着债券指数的计算需要不断调整基期,因为当新的债券上市后,它必须被纳入到指数的计算当中,那么就必须根据上市时的市值对债券总市值进行加总调整。基于上述原理,在指数编制过程中,需要不断地根据新上市债券对指数进行重新校准,这样不仅顺应了上交所债券市场容量的扩张,而且使得指数能够真实的反映整个上交所公司债的整体变化趋势。因此,基于上述第一实施例提出本申请方法的第二实施例。在该实施例中,在所述获取全部成分券在当前交易日的总市值的步骤之前,所述方法还包括步骤:
检测当前交易日相对于前一个交易日是否有新上市债券且新上市债券中有满足所述预设筛选条件的债券;
若当前交易日相对于前一个交易日没有新上市债券,或者新上市的债券中没有满足所述预设筛选条件的债券,则执行所述获取全部成分券在当前交易日的总市值的步骤;
若是,则根据满足所述预设筛选条件的新上市债券更新成分券,并确定新增成分券的发行总数量;
获取更新后的全部成分券在当前交易日的总市值;
根据更新后的全部成分券在当前交易日的总市值、更新前的全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第二指数计算规则计算当前交易日的债券指数。
在本申请中,采用在第一计算规则的分母项中增加调整项的方式得到第二计算规则,其中,第二计算规则的表达式如下:
Figure PCTCN2018102134-appb-000002
其中,∑P i T+1Q i为更新后的全部成分券在当前交易日的总市值,∑Q j为新增成分券的发行总数量。债券在上市交易的第一天,其发行面值为100,因此将100与新上市的符合预设筛选条件的债券的总发明规模的乘积作为调整项。
也就是说,在该实施例中,在每一个交易日都需要检测该交易日是否有新上市债券,并判断这些新上市债券是否满足预设筛选条件,当有满足预设筛选条件的时候,用第二计算规则计算本交易日的债券指数,否则,仍然用第一计算规则计算本交易日的债券指数。
本实施例的方案,考虑到随着时间的推移,指数的成分券会不断扩容,设计了可以不断调整基期的指数编制方法,实现了对指数重新校准,不仅顺应了上交所债券市场容量的扩张,而且使得指数能够真实的反映整个上交所公司债的整体变化趋势。

在图2所示的装置1实施例中,存储器11中存储有债券指数编制程序01;处理器12执行存储器11中存储的债券指数编制程序01时实现如下步骤:
确定目标交易所的债券指数的成分券,其中,所述成分券是从所述目标交易所的所有上市债券中筛选出的符合预设筛选条件的债券。
信用债是指政府之外的主体发行的、约定了确定的本息偿付现金流的债券。例如企业债就是一种信用债。以下以上海证券交易所作为目标交易所,对本申请实施例的方案进行说明。
确定截止日期,从目标交易所在该截止日期之前的所有上市债券中筛选 出符合预设筛选条件的债券,作为该交易所的债券指数的成分券。以上海证券交易所为例,以下简称上交所,统计其在2018年3月28日之前上市的所有债券,从中筛选出符合预设筛选条件的多个债券作为证券指数的成分券。在一些实施例中,预设筛选条件中的筛选指标主要包括剩余期限、主体评级和信用评级、发行规模。预设筛选条件为:剩余期限在预设时长以上,主体评级和信用评级均在预设级别以上,发行规模在预设数量以上的上交所上市公司债债券。当上市债券同时满足以上条件时,判定该上市债券满足所述预设筛选条件。其中,剩余期限是指债券距离到期剩余的时长。
上述预设时长、预设级别以及预设数量的选择可以根据交易所的上市债券的实际情况进行合理设置。优选地,在一实施例中,预设时长为1年,预设数量为20亿,预设级别为AA级。关于发行规模,基于债券规模越大,资产配置容量越高的逻辑,指数的标的选在债券发行规模20亿以上,为后期的债券ETF复制提供了现实的操作空间。此外,关于预设级别的设置,市场上现存的一些指数,其主体评级和信用评级设置的门槛较低,基本上涵盖了所有投资级以上的公司债债券,这样的指数作为一个代表公式债整体的指数是无可厚非的,但是作为债券ETF的跟踪标的则是不合适的。而且市场上现存的一些指数没有考虑剩余期限的问题,这对于债券ETF的跟踪标的也是不合适的,因为如果复制的债券的成分券的剩余期限过短,基金会面临频繁调仓的问题,导致面临补券风险,造成交易成本增加,影响整个基金的收益水平。

获取全部成分券在前一个交易日的总市值,以及前一个交易日的债券指数的数值。
获取全部成分券在当前交易日的总市值。
根据获取的全部成分券在当前交易日的总市值、全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第一指数计算规则计算当前交易日的债券指数。
在确定成分券之后,根据成分券的市值计算目标交易日的债券指数,在 本实施例中采用的第一指数计算规则是利用成分券在当前交易日的前一个交易日的总市值、前一个交易日的债券指数的数值以及在全部成分券在当前交易日的总市值来计算当前交易日的债券指数的数值。由于对于第一个交易日来说,其指数是确定的,即该指数在第一个交易日的初始值为100。在每个交易日结束后,可以获取到成分券的总市值,因此,就可以计算得到第二个交易日的债券指数的数值,以此类推,可以计算得到或许每一个交易日的债券指数的数值。

上述公式中,P i T+1为T+1交易日的债券i的收盘价,Q i为发行规模,所有债券在一个交易日结束后的收盘价与发行规模的乘积之和为总市值。T交易日的总市值的计算方式同理。
本实施例提出的债券指数编制装置,确定目标交易所的债券指数的成分券,成分券是从该目标交易所的所有上市债券中筛选出的符合预设筛选条件的债券;获取全部成分券在前一个交易日的总市值,以及前一个交易日的债券指数的数值;获取全部成分券在当前交易日的总市值;根据获取的全部成分券在当前交易日的总市值、全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第一指数计算规则计算当前交易日的债券指数。本申请中将符合预设筛选条件的债券作为债券指数的成分券,并根据交易日里的成分券的市值预设的指数计算规则计算当前交易日的债券指数,实现了针对信用债的债券指数计算方案。

根据更新后的全部成分券在当前交易日的总市值、更新前的全部成分券在前一个交易日的总市值、前一个交易日的债券指数的数值以及预设的第二指数计算规则计算当前交易日的债券指数。
在本申请中,采用在第一计算规则的分母项中增加调整项的方式得到第二计算规则,其中,第二计算规则的表达式如下:

其中,∑P i T+1Q i为更新后的全部成分券在当前交易日的总市值,∑Q j为新增成分券的发行总数量。债券在上市交易的第一天,其发行面值为100,因此将100与新上市的符合预设筛选条件的债券的总发明规模的乘积作为调整项。
