On CAPS, 34% of the 517 members who have rated Zillow believe the stock will underperform the S&P 500 going forward.

Just last week, one of those Fools, All-Star JakilaTheHun, wroted that the Zillow bear case all boiled down to price:

Complete insane at nearly 20x revenues. Zillow is a rapidly growing firm and may have a bright future, but too many investors misunderstand the dynamics with the company. Zillow is not like LinkedIn (LNKD.DL) or Netflix (NFLX -3.92%). LNKD and NFLX both have high operating leverage, which means that for every dollar of incremental revenue, a very large chunk of that goes to profit. Z is closer to the other end of the spectrum, as it has to spend a considerable amount of money to generate each incremental dollar of revenue.

Given the dynamics with Z, it should sell closer to 3x-5x revenues. That's assuming you buy into the thesis that it's a high-growth company with a good future in the industry (which I think is reasonable, but it's still not a given). That would put its valuation closer to $15-$25; quite a bit below the current price of $75. I think Zillow is extremely overvalued right now.
