Is the turnaround finally working? Maybe - just maybe. Sales rose 7.1%, to $12.3 billion, and operating income 32%, to $556 million, in fiscal 2007. The key: innovation. Since 2005, Sara Lee has accounted for almost half the new bakery products in the U.S., and Barnes plans to launch 75 new products in 2008. The stock price, alas, has barely budged. Investors worry that margins will stay slim because of increased marketing spending.
