CEO, Lululemon Athletica
There's no Savasana in sight for Day or her fast-growing yoga apparel company, Lululemon Athletica (. The Canadian retailer's stock is up 40% this year, and 290% since Day, a former Starbucks exec who got her start as Howard Schultz's assistant, took the top spot at the company in 2008. Day has demonstrated her strategic gifts in the role: she's won over Lululemon's loyal flocks by cultivating a sense of scarcity around the pricey yoga gear (discounts are rare). The counter-intuitive move is working: Lululemon expects $1.4 billion in sales this year. That's up more than $300 million from 2011 and well ahead of the crop of competitors, like Gap's Athleta, which have begun to sell fashion-forward sportswear at slightly lower prices. --EF )
