On CAPS, 35% of the 617 members who have rated lululemon believe the stock will underperform the S&P 500 going forward. These bears include All-Star STAINEDGLASSER, who is ranked in the top 10% of our community, and bofors.

This past summer, STAINEDGLASSER tapped lululemon as a particularly sour opportunity: "Yes Yoga is a big trend right now, however their clothing is not unique, not that attractive, and is expensive! My gut tells me that in this economy, people are still watching their bucks and these items won't make the buy list."

While lululemon has experienced some steady growth in recent years, many in our community think its shares are just too hot to touch right now. The stock is up 77% over the past year and trades at a lofty price-to-cash flow of 26 -- a premium to publically traded foes Nike (15.2), Finish Line (5.6), and even the high-flying Under Armour (24.2). With the apparel industry as fickle as it is, CAPS member bofors believes lululemon shares are primed for the proverbial pullback:

(1) [lululemon] appears maintained a ceiling at $45 for the last six months. ...
(4) [lululemon's] P/E ratio of 37 cannot be maintained because its growth rate has to slow.
(5) [lululemon's] products are clearly overpriced fads, whose novelty is certainly wearing off years after their introduction.
(6) [lululemon's] revenue will be affected by discount and non-discount imitators including Nike. ..

In short, although [lululemon]continues to be an extremely successful company it appear quite that the rapid downfall of its share price is being widely anticipated and promoted. Otherwise, it has a very clear pattern of wide oscillation currently.
