I thought Moody and S&P ratings were for bonds or debt not equity which is what people seem to be talking about. Sure the stock will continue to be devalued by the continuous bad news. From what I understand is the lowering of rating means that those willing to loan Sony money are going to ask for higher interest rates to compensate for the perceived increase in risk. That would mean that you are better off buying a Sony corporate bond than an actual stock.
From what I see from Sony's financial report is a struggling company but the numbers aren't as bad as they could be. The restructuring is bringing in some improvements. I am not counting out sony yet. In my opinion though I would sell the television portion of Home Entertainment Division and downsize the imaging product and solutions division. Finally, (I know this won't be popular here) I would take a good look at the game division. With the poor Vita sales and the continued decline of the PSP and PS3, I just can't see where they are going. To me it looks like they are putting a lot of faith in a breakout success from the PS4. With its current poor handling of this division, I am genuinely concerned about the Game divisions future. My advise would be to either beef up support of the PS3 and PSP in order to bring in as much short term profits as possible or "relaunch" the Vita with a better marketing front, some first party games, and a more consumer concious price.
