For some a while I have been investing in retail bonds. With yields in saving accounts being so poor these are an alternative. There is risk involved as they are a non-protected product and some of the companies issuing, although themselves listed, carry risk.
If you invest at inception not only do you get good yields but also the potential for a capital gain as generally they list on the LSE at a higher price when the initial offer closes. A good example is the Tesco 5% Bond which listed at 100p but is now priced at 103.5/104.45
