Lululemon, which my firm, Belus Capital Advisors, rates a sell, will announce its second-quarter earnings on Sept. 11, its second full period with CEO Laurent Potdevin at the helm. When it announced its first-quarter earnings in June, Lululemon warned about sales and profits in large part because of investments being made in the supply chain and product quality. For the second quarter, Lululemon called for revenue of $375 million to $380 million based on a comparable-store sales decrease in the low- to mid-single digits. Earnings per share are expected to be in the range of 28 cents to 30 cents.
