A Bartiromo Bounce?

Most stocks that CNBC anchor Maria Bartiromo mentioned in a positive way on her Midday Call program in early 2000 had started moving up sharply about 10 minutes before her report, while stocks she mentioned in a negative way had moved down, according to a new study by Jeffrey Busse and Clifton Green, finance professors at Emory University's Goizueta Business School. The study supports the notion that Wall Streeters have fed Bartiromo market-moving information and traded before she aired it. In his book Trading with the Enemy, Nicholas Maier alleges that his former boss, trader and pundit Jim Cramer, was one of those who gamed Bartiromo. Cramer denies the accusation. Says CNBC: "We firmly stand by the work, ethics and integrity of Maria."
