Wayfair shares slump as much as 16%, hitting a four-month low intraday, after the home goods retailer said it expects mid-single-digit topline growth year-over-year for the first quarter, which Jefferies considers to be conservative and attributable to colder weather to start the year. The company also said during the conference call that it sees 1Q gross margins “likely at the low end” of the 30% to 31% guidance range. Wayfair Chief Financial Officer Kate Gulliver joins Bloomberg Businessweek Daily to discuss. She speaks with Carol Massar and Tim Stenovec. (Source: Bloomberg)
