Based on the aggregated intelligence of 125,000-plus investors participating in Motley Fool CAPS, the Fool's free investing community, online jeweler Blue Nile (NASDAQ:NILE) has received the distressing two-star ranking. While one-star stocks have been the worst performers, our data has shown that two-star stocks still lag the market by a significant margin and should be approached with caution; conversely, highly rated stocks have outperformed the S&P.

Over on CAPS, 61 of the 174 All-Star members who have rated Blue Nile -- or 35% -- believe the stock will underperform the S&P 500 going forward. These bears include goofyfool and TSIF, both of whom are ranked near the top 10% of our community.

Last month, goofyfool noted that the Blue Nile bear case all boiled down to price: "Overvalued on most fundamental ratios (P/E, P/S, P/B, and P/CF), margins are shrinking, and oh yeah, we're in a recession."

In a pitch from two weeks ago, TSIF also questions the seemingly steep valuation:

While ROE/ROA are very respectable and NILE has no debt ... [a]ctual book value is $1.05 PER share on a $23 stock ... [which] would be scary even for a stock that was soaring. Either I'm out of my element here or this company was not living up to potential before the recession. Even in a recession, engagement/wedding bands might not be discretionary, but number of carats is! Maybe I'm jaded here, but this diamond doesn't have the luster that its price tag is demanding.
