同学你好
ABS是标的资产不是住房贷款 (non-mortgage)的结构化产品。通常的标的资产包括:automobile loans;automobile lease receivables;credit card receivables;student loans;bank loans;accounts receivable(理论上,一个资产可以产生分层的现金流,就可以作为ABS的标的资产),其优点与MBS相同。他的优点是 Can express views on consumer credit:可对消费信贷表达意见,例如,经济开始向好,消费信心开始提振,应该买入ABS;经济下行,消费降级,信用卡可能违约,导致ABS风险变大。
ABS是资产池类的资产,但是ABS通常不分层。

Collateralized Debt Obligations(CDOs):本质是一揽子负债放到一个资金池中进行证券化 (security backed by a diversified pool of one or more debt obligations),按不同优先级分为多个tranche。 (Super senior tranche,Senior tranche,Mezzanine tranche,Equity tranche)
关于CDO的几个重要结论
Correlation tend to be highly negative,can profit by selling the subordinated,buying the senior tranche.
Correlation tend to be highly positive,can profit by buying the subordinated,,selling the senior tranche.
Correlation↑,the value of equity tranches usually↑(relative to the value of senior and mezzanine tranches).
相关性提高,应该买次级产品,equity tranches价格更便宜。
Advantages优点
◼ Relative value:CDO的估值可能与构成CDO的标的抵押品的估值不同。
◼ Leveraged Exposure to Credit:融资成本低于构成CDO的标的资产的收益,因此有杠杆。
Disadvantages缺点
◼ Do not provide much diversification. 没有提供分散化。(因为CDO的抵押品通常是企业贷款或者企业债,由于基础资产就集中在这两种类型上,所以分散化效果差)
◼ Do not offer unique exposure to a sector or market factor. 没有提供某个板块或市场因素的特定敞口。
