CNBC "Halftime Report" trader Jon Najarian bought shares of Best Buy on Monday, after spotting unusual activity in the options market.

Najarian, who is leading CNBC Pro's Model Portfolio competition this year, up 11 percent, believes the bulls are shopping for more upside on the stock.

In the past week, shares of BBY rallied 24 percent, after the consumer electronics retailer reported better-than-expected sales and raised its guidance ahead of estimates.
