Starbucks (SBUX) is set to have a good morning, as the company received an upgrade from UBS to buy from neutral. The brokerage also upped its earnings forecast for Starbucks to $1.14 per share in fiscal 2010, up from $1.09 per share. For 2011, UBS expects Starbucks to pull in $1.34 per share, seven cents better than the brokerage's earlier forecast. UBS believes that benign costs and Starbucks' ongoing productivity programs are key to the company's success. That said, UBS feels that McDonald's (MCD) foray into the world of frappes and smoothies could "cannibalize frappuccino consumers from Starbucks." Such a move could hurt Starbucks' bottom line.

Campbell Soup

The Wall Street Journal reports, however, that "should Starbucks indulge in Godiva, which Campbell put up for sale in August, it would be a departure from its modus operandi." Wall Street experts put the price of Godiva at around $800 million.

If Starbucks buys Godiva, it would be a huge mistake. The coffee retailer's shares are near a 52-week low, trading at under $26. They have a 52-week high of more than $40.

The doubts about Starbucks center around its long-term goal of having 40,000 stores worldwide. Investors are concerned that current same-store sales may be too weak to support that kind of expansion. If Starbucks goes into a second business without fixing its first, the company's stock could take another hit.

Godiva may seem like a sweet deal, but all it would do is take Starbucks' eyes off the ball.
