Why Lululemon stock surged 17 per cent in December

If there was any lingering doubt that CEO Laurent Potdevin had moved Lululemon Athletica past its troubles that started in 2013 with see-through tights, dismissive statements by the founder, boardroom infighting and stagnant same-store sales, it was banished in December. The company’s stock punched through its trading range of the past few years with a 17.4-per-cent gain on the back of quarterly results that exceeded analysts’ expectations.
