On CAPS, 69% of the 1,042 members who have rated Overstock believe the stock will underperform the S&P 500 going forward. These bears include chinamantsan and TMFBiggles.

Just last week, chinamantsan touched on a few of Overstock's negatives: "Just can't compete in the online marketplace now. With receiving less traffic to their website and fewer conversions on sales, I think Overstock will be going away soon."

Currently, Overstock even trades at a particularly lofty PEG ratio of 4.8. That represents a premium to rivals Amazon (3.6), eBay (1.3), and Wal-Mart (1.1).

CAPS member TMFBiggles elaborates on the Overstock bear case:

If you can't do well selling supposedly bargain-basement stuff in the current Grouponzi economy, then why expect a turnaround when people eventually decide to loosen the belt buckle?

P/E is high and earnings trending south, double whammy for future drops. Angry, defiant CEOs are never (or very rarely) confidence-builders.
