LuLulemon Athletica (LULU) is surging in after hours on guidance and the announcement of a $100 million stock buyback. The question though is whether guidance is enough to really move the stock higher. LuLulemon guided to an EPS of $2.11 to $2.16 for the year with analysts at $2.12. The Q4 estimates actually appear below analyst estimates though the company did provide a encouraging data point that business had picked up. In the end though, why would one want to pay $67 in after hours for a stock only positioned to earn around $2.15 for the year?Disclosure: No position
