...this might put a damper on our hopes for inclusion in the S&P 500. I'm not sure how those two arms of the agency interact, but this seems like it would make that less likely...
I spoke a few months ago with a friend who is an executive at S&P. He assured me that there are walls separating those who rate stocks and bonds from those who determine which companies are added or deleted from the S&P 500.
There were only 19,000 shares traded after hours today. The price action is meaningless.
The S&P rating of Tesla Motors debt appeared in the TSLA news section of my TD Ameritrade account through Dow Jones an hour and a half before the regular market close today. The share price actually closed higher than at the time that report appeared in my account.
