先假设债券价格不变,(事实上不可能)一般债券的利息不会特别高与市场水平,如果说市场利息是5%,这个公司债券是30%,市场价格不变,我看您也不敢买,这个不敢买就是风险,就是出售方无法返还本金的风险 (counter party risk。出售方利用高的利息(premium)吸引购买者是有一定原因的。出售方可以有能力支出利息,但是无力偿还本金,投资者还是得不偿失啊。
normally,coupan rate=risk-free rate+maturity premium+liquidity premium+default's compensation
so,if coupan rate 's higher, normally,it means that the latter three terms of the equation above are larger,we can't say that's good
