NEW YORK -- European snack company Mondelez (MDLZ) has been running, and the bulls are looking for a breakout. 

OptionMonster's Heat Seeker tracking system detected the purchase of about 12,500 December 40 calls Wednesday, most of which priced for 34 cents. Volume was almost seven times the previous open interest in the strike, which indicates that new money was put to work. The trade was highlighted by optionMONSTER co-founder Jon "DRJ" Najarian on CNBC's "Halftime Report" on Wednesday. 

Long calls lock in the price where stock can be bought, allowing investors to profit from a rally while risking much less capital than they would need to own shares. The contracts can also generate significant leverage if the stock moves higher. 

Mondelez, part of the old Kraft Foods empire, rose 1.05% to $39.10 on Wednesday. Although that was its highest closing price ever, the stock remains below last summer's intraday high of $39.54. 

The options have clearly shown the way in this name, handing our customers profitable upside trades in February and July, followed by a big winner to the downside in August. 

More than 25,000 contracts changed hands in the name overall Wednesday, almost five times its daily average for the last month. Total calls outnumbered puts by a highly bullish 37-to-1 ratio.
