Slightly off-topic, but in 2011 when Moody's downgraded the US credit rating, we all were saying "well, Moody's is feeling a bit moody". The US continued to struggle in fits and spurts in some industries. But lately, it has been all "risk-on" for most traders. We have been through a few "asian asset bubbles" before. Whether this is the big one is anybody's guess, but sometimes the broken doomsday clock gets the time…
That was S&P. It coincided with the SEC and the Justice Department investigating them for fraudulently overrating mortgage back securities.
Moody's downgraded on June 2 2011... or should I say at least "changed outlook to negative"
