On CAPS, 36% of the 273 members who have rated Public Storage believe the stock will underperform the S&P 500 going forward.

Just last week, one of those Fools, All-Star joryko, wrote that the Public Storage bear case all boiled down to price:

Tremendously overvalued by almost any basic valuation technique. Graham number sits at only $66 using 2012's EPS estimates. Forward P/E above 20 and 5 year PEG is 3.5

I understand that it is a relatively safe and predictable company but it has bounced up way too high, even with its dividend.

[Public Storage] might be a well run company but it will not outperform the S&P 500 at these prices.
