Near as I can tell stocks have little to do with the US debt rating. When I bought stock I usually used a broker, not the Gov. Clearly there is some market funny business a foot. Note the volume of late is extreme, its a giant spike. So whats rocking the boat? Some institution but which is unclear.
What is clear a lot of folks went for the mutual fund retirement programs that will fail. Perhaps that's the news at hand. Its not social security that is not funded, but the mutual funds.
