Stocks in the news: AIG, UPS, Macy's, Toll Brothers

AIG (AIG) CEO Robert Benmosche has threatened to step down from the top job only three months after taking it as he struggles to deal with heavy government oversight and restrictions on pay to employees, according to the Wall Street Journal. Shares declined over 1.5% in premarket trading.

UPS (UPS), which is often seen as a bellwether to the economy, now expects growth in its volumes next year as the global economy gradually recovers, its CEO said on Wednesday, Reuters reported. UPS will hike shipping rates for 2010. He also expects the holiday season to be slightly better than estimated. Shares rose over 2% ahead of the bell.
