Over on CAPS, fully 697 of the 993 members who have rated Overstock -- some 70% -- believe the stock will underperform the S&P 500 going forward. These Fools include stan8331 and CAPS All-Star TheHuney.

Two weeks ago, stan8331 looked at the stock from a consumer standpoint:

I've bought a few things from overstock.com in the past, but for an extended period now, every time I visit the website I see overpriced stuff I don't need. Amazon.com and Buy.com offer better deals and better consumer experiences - I can't see Overstock.com gaining any ground in the foreseeable future.

In a pitch just one day later, TheHuney shares that sentiment, providing some numbers to reinforce those bearish observations:

... they are operating at a loss, and have been cash flow negative over the past nine months. I've never known anyone who shops at their website and I can't imagine any potential buyers lining up to make an offer for this company. Throw in fuzzy accounting over the past several years and a potential SEC investigation and this thing seems like it might be toast to me.
