Cbeyond Inc. (NASDAQ: CBEY) cut to Underperform at BofA/ML.

Cisco Systems Inc. (NASDAQ: CSCO) maintained as Outperform with a $25 target at Credit Suisse, but it said that it is migrating in its stage from a growth company to a value company.

Discover Financial Services (NYSE: DFS) named Bull of the Day at Zacks and cut to Hold at Argus.

Credit Suisse changed their methodology for covering stocks yesterday and the changes affected about 65 U.S. companies and 20 or so Canadian companies. Most resulted in downgrades, many of which went from an already cautious stance of Neutral to a much worse Underperform rating. The wave of downgrades would make a simple market observer think a crash was coming.
