Lululemon had many things going for it this Christmas season which should boost revenue in 4Q more than expected, according to Sharon Zackfia of William Blair in a note. The analyst says “store traffic was robust during our pre- and post-Christmas checks, and similar to last year, there was little markdown activity prior to Christmas.” Zackfia also says unseasonably mild weather helped holiday traffic. She now expects revenue growth to be 16% in 4Q, up from 15% previously and ahead of guidance of between 13% and 14%. She estimates 4Q EPS up 14% to $5.02, ahead of consensus of $4.95 and guidance of $4.85 to $4.93.
