On CAPS, 35% of the 91 members who have rated Valhi believe the stock will underperform the S&P 500 going forward. These bears include davidm9999 and Jeffrey2012.

Late last month, davidm9999 touched on the stock's seemingly unsustainable valuation: "[Valhi's] P/E is reminiscent of other bubble companies -- like [Netflix], [Research In Motion], and [Green Mountain Coffee]. Look to see it fall hard in the coming year."

In fact, Valhi currently sports a lofty P/E of 56. That represents a clear premium to other chemical plays like Dow Chemical (NYSE: DOW) (12), DuPont (13), and Huntsman (10).

CAPS member Jeffrey2012 elaborates on the bear case:

This is an overvalued holding company that is having way too much of a rosy picture in terms of future prospects. ...

I seriously believe that the performance crowd has started to chase this to the moon since they see [Chairman Harold Simmons] buying so many of the shares and it's consistently gone up. But the run up has been way over done and a serious risk of overheating. I fear that many people don't quite understand all of their holdings and just see that it's gone up so it must continue going up. ...

This is definitely an interesting company and if it could drop down to a more reasonable price point then it would become a more rewarding investment going forward.
