Canadian investor Prem Watsa doubles down again on what was already a big investment in Research In Motion (RIMM), as a filing shows his Fairfax Financial (FRFHF.PK) goes to 51.9M shares - worth about $351M, a 9.9% stake. Watsa figures RIMM's undervalued and recovery could take three to five years.
