On CAPS, 49% of the 1,740 members who have rated Salesforce believe the stock will underperform the S&P 500 going forward. These bears include smartin619 and Brooklynvestor.

Earlier this fall, smartin619 succinctly summed up the Salesforce bear case: "Increased competition will slow growth and make the current P/E unsustainable."

In fact, Salesforce sports a particularly lofty forward P/E of 66. That represents a clear premium to rivals like Microsoft (9), Oracle (11), and SAP (18).

CAPS member Brooklynvestor expands on the underperform argument:

Company is making too many acquisitions and becoming bloated. ... The "social enterprise" is a speculation. Free and cheaper alternatives (SugarCRM and MSFT Dynamics, for example) are encroaching, creating pricing pressure. Sales commissions and stock options are eating up the company's value. Oh and the valuation is absurd. I'm loving the risk/reward proposition of shorting [Salesforce].
