Burger King Holdings (BKC) is poised to edge higher this morning after it was upgraded from "hold" to "buy" at Deutsche Bank after a 60% underperformance relative to the market over the past year. "While the stock has bounced a bit recently, we see room for further upside from here as sales and margins remain well below cyclical peaks and as investors may begin to seek out cheaper names that can still benefit from a recovering economy," the broker said.

There is ample room for more analysts to jump on the stock's bandwagon. According to Zacks, the stock has earned 14 "hold" ratings and just four "strong buys." Should more of the brokerage firms jump shift to the bulls' camp, it could increase the buying pressure on the shares.

In fact, options players are already starting to make the switch to the bulls' camp. The International Securities Exchange (ISE) has reported more than five calls purchased to open for every one put purchased to open during the past 10 trading sessions. This ratio of calls to puts is higher than 76% of all those taken during the past 12 months, pointing to a rising optimism.

However, there is still room for optimistic sentiment to grow. The Schaeffer's put/call open interest ratio comes in at 1.29, which is higher than 74% of all those taken during the past 12 months. In other words, short-term options players have been more pessimistically aligned toward the shares only 26% of the time during the past year.
