BlackBerry Rallies 19%; Quiet Holiday Week Could Test QNX Momentum
BlackBerry’s U.S. shares surged 18.95% Friday to $7.91. The stock in Toronto finished the day up 18.52% at C$10.88. With the U.S. market closed Monday for Memorial Day and no trading Sunday, the rally sets up a test this week to see if traders stick with BlackBerry as a software-growth name or if Friday was just a quick squeeze.
