If would be very interesting to see if any of the Credit Suisse traders had a substantial
short position in the stock before the downgrade. I have a distinct memory three bond traders.
"The government charged three former Credit Suisse traders on Wednesday with inflating the value of mortgage bonds as the housing market collapsed, a rare criminal prosecution of Wall Street executives for their conduct during the financial crisis." February 1, 2012, 7:41
Just business as usual for these gentlemen, another day.
Key to watch always is how we trade and volume. The actual content of most of these type of downgrades is opinionated and subject to debate on future decisions from management. Minor effect, long term for all purposes but helpful for short term entries, IMO.
Quiet whispers between key large trading desks, is the undercover action for these plays. Some short action, a little fear and panic from analysts, leads to selling. Opportunity presents to buying these dips at reduced prices, facilitating exit of short term players and entry for new longer term larger investors.
