On CAPS, 40% of the 82 members who have rated RealD believe the stock will underperform the S&P 500 going forward. These bears include Clint35 and AcheronRecords.

Just last month, Clint35 noted that RealD's negatives completely outweigh its positives: "This company has two good things going for it. High insider ownership and a good balance sheet. Everything else is bad news."

RealD even sports a particularly lofty forward P/E of 31. That represents a clear premium to listed rivals like Dolby Labs (15), IMAX (21), and NVIDIA (13).

CAPS member AcheronRecords elaborates on the RealD bear case:

3D has been a fad that has been falling in and out of fashion for decades. They rode the wave up, but now with Pirates and Kung Fu Panda 2 showing weak demand for 3D maybe studios will think twice before converting nearly every movie into 3D. I know I drove 15 minutes past the closest movie theater just to see Thor in 2D, and the 4 people we went with agreed that it was worth the drive to avoid the 3D.

Lookout for the dropping share of box office receipts from 3D.
