casapinos, there's sometimes a trade to be had in the rights arbitrage. e.g. if you can long RRN for less than 32p below you can short RR. You then close when the arb narrows or take up the rights to net off the RR. short.
That's what quite a few traders, including me, did with HMSO/HMON because there was a very good arbitrage to be had, with HMON trading way below the logical level. I think that was due to the extraordinarily deep rights (25 for 1 as I recall), smack in the middle of a FTSE relegation (how daft is that, when you have index funds in the mix).
Whilst to the uninitiated it may look risk neutral there's always the danger of the short side being called in at very short notice, as they tried to do with HMSO.
