See-through yoga pants are pretty funny, so lululemon athleticas (LULU) recall of such and the resulting profit warning Monday had a whiff of whimsy to it. But considering this mistake seriously hits the one thing that keeps lululemon shares very highly valued its big sales gains it will surely bring forward the question thats been on a lot of lulu investors minds lately. That is: can lululemon continue to deliver what Wall Street expects of it?

Well get a better idea on Thursday, when lululemon reports fourth quarter results and updates first quarter forecasts. From Mondays recall announcement, we already know a few things. Pants that make up about 17% of all bottoms sold in its stores are too opaque, and lululemon is pulling them off the shelves. That will put about a 4% dent in sales in the first quarter, according to the warning, which had been expected to rise about 30%. Comparable store sales gains in the first quarter are expected to be between 5% and 8% instead of the 11% earlier predicted. The company is still working on a profit estimate for the quarter.

While most retailers would kill for a 6% comp sales gain these days, lululemon is no ordinary retail investment. Wall Street expects very big sales and profit gains from lululemon, as evidenced by its share valuations, including PE ratio. Take a look at lululemons forward price to sales ratio compared to Under Armour (UA), a competitor that is also wildly popular with investors.

Even before the exposure problem, lululemons same store sales growth was forecasted to slow from great gains that propelled the stock in past years. While the shares still have a lot of fans the companys $100-plus yoga pants are still hugely popular worriers have emerged recently. Concerted competition from Nike (NKE), Under Armour and department stores may eventually eat at lululemons great profit margins. Manufacturing problems not unlike the one that led to see-through pants have hurt sales at couple of times before. Bank of America Merrill Lynch has a sell rating on the shares.

The two stock charts below show lululemons share price since its 2007 IPO, and then a close-up of the change in price since it announced the recall Monday morning. Perhaps there are clues there about lululemon shareholder intentions. Was the level of selling these two days commensurate with the news delivered? Or does it seem this was the excuse a lot of shareholders were looking to take profits? You decide.
