固定收益类别中的莠草(1)
在不能为投资组合创造价值的各种资产类别中,除美国国债以外的固定收益类别是最主要的一种。在固定收益资产类别中,虽然无违约风险、不可赎回、享有美国政府完全信用担保的美国国债在投资组合中扮演最基本的角色、赋予投资组合价值并使其有别于其他组合,但是,投资级别公司债券、高收益债券、外国债券和资产支持证券包含诸多缺点,因此不能把它们纳入精心构建的投资组合中。固定收益资产类别中,非核心资产占据一大部分。许多市场参与者将资产配置到公司债券和房屋抵押贷款支持证券中,寄希望于在不承担额外风险的同时创造出增量收益。投资者要理解固定收益资产类别中各种投资品种的缺点,特别是理解这些品种能否发挥固定收益资产类别在组合中应当发挥的作用,这样有助于做出合理的组合决策。
