On CAPS, 15% of the 135 members who have rated Crown Castle believe the stock will underperform the S&P 500 going forward. These bears include EEE1 and All-Star jed71, who is ranked in the top 15% of our community.

Last month, EEE1 showed skepticism over the stock's surprising price strength:

The last time that I checked, this company was still losing a lot of money, had a sky-high, forward PE ratio of 266, a huge debt load of $6.54 B, and net tangible assets of negative $1.5 B. Miraculously, the stock has increased over 3-fold since November, 2008. Sooner or later, it has to come back down to earth and reality.

In a pitch from three weeks later, jed71 elaborates. Here's an excerpt:

It is sitting close to a 52 week high and poised for a large correction. ... With long term debt of $6BB, their income statement just can't handle the heavy interest expense every month. I just can't see how they can get themselves to a decent level of profitability without whittling this down in a major way. And that usually means a large share dilution or some other negative steps that impact shareholders. ... This looks like a decent short opportunity given the lack of fundamentals to support the last year's price move. With a beta of close to 2, though, you might be in for a wild ride.
