CVC's attempt to buy J Sainsbury appears to be over
http://news.independent.co.uk/business/news/article2442076.ece
with the 5Y CDS spread trading at ~45 bps, down from its peak of ~130 bps, but still above the spread of ~25bps 6 months ago.
However, as can be seen from the chart below, the share price hasn't decreased by as much. If it mirrored the CDS spread, i would expect it to return to below £5.00.

Two things to note:
- Usually share prices and CDS spreads move in opposite directions - if a company is in trouble the shares go down as the perception is that the company is worth less and the CDS spreads increase because there is more likelihood of default. A leveraged buyout is different. The CDS spreads increase because the buyout will be financed using debt, making the company more risky, and the share price usually increase because the potential bidder tends to offer more than the market value to tempt people to buy into the offer
- In common with several other entities (Nokia being one that springs to mind), Sainsbury does not have any unsecured debt outstanding

I used to hold SBRY when it paid a good yield (around 6%) but sold it when the dividend cut was announced. If I were to attempt to make money from my above beliefs, I would either
- Go short on SBRY stock
- If I was worried about a buyout still happening (and assuming I could trade CDS as a private investor), I would buy CDS protection as a hedge.
