BlackBerry Revival Rewards Watsa’s Patience With Huge Gain Bloomberg 1/27/2021 Michael Bellusci (Bloomberg) -- Day traders have pushed BlackBerry Ltd.’s share price to levels not seen in more than nine years. They’ve also given a jolt to a Canadian investment company that got crushed in last spring’s market crash. BlackBerry soared as much as 52% Wednesday in New York after a brief trading halt. The stock reached its highest level since 2011, and is up about 300% this year. That is repaying the patience of Prem Watsa and his Fairfax Financial Holdings Ltd., which owns 8.3% of the software firm’s shares, according to data compiled by Bloomberg.
