On CAPS, 45% of the 1,274 members who have rated Salesforce believe the stock will underperform the S&P 500 going forward. These bears include Endeavor1 and All-Star TSIF, who is ranked in the top 0.5% of our community.

Late last month, Endeavor1 touched on the stock's seemingly unsustainable price run:

A great offering, that seems to have just ballooned in price from emotion. Lots of firms would seem to have made big money on this that they will look to book at the first sign of sustained weakness in the market. This stock could fall 20% and there be no change in any narrative from either side of speculation right?

While our community acknowledges Salesforce's leadership position in the CRM space, they can't seem to get over the stock's nosebleed valuation. Salesforce might be posting a healthy gross margin and solid growth rates now. But many Fools argue that the company lacks the competitive moat to prevent well-financed software behemoths like Oracle, Microsoft, and SAP from eventually cutting into them -- and deeply. If that ever happens, CAPS All-Stars like TSIF warn that the stock has plenty of room to plunge:

I've learned and can accept many metrics of price appreciation that warrants a high P/E, P/B. In a market mover company, with high margins, high growth, and a wide moat, I can learn to respect a much higher valuation than warranted by current results. In the case of Salesforce.com, however, margins and growth aren't anywhere near what would warrant a P/B of over 11. Insiders are selling their "gifted" shares in Million dollar increments on a regular basis. At some point, while one can never have too much money, I'm guessing they will start taking time to enjoy some of it. The co-founder and CEO is now a Billionaire at age 45. ... Any bad news and deflation will occur rapidly. When and if that will occur however, is just a guess on my part, but in general, what goes up, will eventually stabilize at some appropriate altitude.
