Stock Downgrades: Messing With Texas Instruments

We welcome March this week but Groundhog Day clearly doesn't want to let go. Stocks slumped and volatility surged as Italian angst returned; investors have indeed been here before. The Dow (^DJI) plunged to its lowest level since January 23 after it became clear Rome remains torn between a convict and a comedian. (And you thought our politics were crazy.)

Pity our 16th president. Fresh from being the victim of a comedian who killed before a billion people, he had to watch from on high as Lincoln National (LNC) fell 4.71% and Lincoln Educational (LINC) lost 4.85% in especially torrid trading for the insurance and educational sectors.

BP Plc (BP), whose former CEO would like his "life back," tumbled 3.42% amid ongoing Gulf of Mexico legal angst. Cemetery stock StoneMor Partners (STON), whose clients are alas unlikely to enjoy what Tony Hayward so desires, surged 1.74% and fellow funeral firm Carriage Services (CSV) rose 2.38% after-hours. Amgen (AMGN) advanced 3.14% to top the S&P 500 (^GSPC). It stands at a fresh all-time peak after appropriately-named analyst Boris Peaker at Oppenheimer sung the biotech's praises.

Today in economics, new home sales for January and February consumer confidence are each expected to tick up at 10:00 a.m. Eastern, and Fed head Ben Bernanke begins two days of testimony on Capitol Hill.

Donnelley (RRD), Saks Inc. (SKS), TiVo Inc. (TIVO), and Vivendi (VIVHY) are all due to report results.
