On CAPS, 29% of the 966 members who have rated lululemon believe the stock will underperform the S&P 500 going forward. These bears include Gti303 and noahfarb.

Earlier this month, Gti303 wrote that the lululemon bear case boiled down to price: "LULU is a great company, great growth, great product, and very green ... however, the stock price is unjustified at this point ... even though there is a pending split."

In fact, lululemon currently sports a forward P/E of 36.4. That represents a clear premium to listed competitors Finish Line (12.8), Gap (10.3), and Nike (16.2).

CAPS member noahfarb elaborates on the lululemon bear case:

Good company. Way overpriced. At this basis, investors are paying not only for the success of their current NA growth strategy, but are also paying for growth beyond NA, which is very uncertain. This is a company that may do very well over the next several years, but that's already priced in. Definitely "UNDERPERFORM".
