NEW YORK (TheStreet) -- BlackBerry stock advanced by 3.64% to $7.12 in Friday's trading session, after the smartphone maker received approval to more than double its share buyback program.

The company can now repurchase as much as 5.8% of its public float.

BlackBerry will be able to repurchase up to 27 million shares, compared to its previous limit of 12 million shares. 

From June 29 to January 26, the company purchased about 9.92 million shares at an average price of $7.43 per share.
