Movie theater stocks plummeted on Wall Street Friday in the wake of a shooting spree at a suburban Denver premiere of the Batman film "The Dark Knight Rises."
Cinemark, the company that owns the theater where a gunman killed 12 and injured up to 59, took a dive in early trading, falling to -4.6 percent.
The country's largest chain, Regal, also sank -4.4 percent.
IMAX faired slightly better, falling to -2 percent.

Originally an outlier, Georgia-based Carmike Cinemas rallied into the black at 0.2 percent Friday morning, but nosedived to -2.3 percent by markets' close.
But theater chains were not the only companies whose prices plummeted.
National CineMedia, an ad sales company, steadily declined to -4.2 percent and 3D technology firm RealD fell to -0.2 percent in the morning and plateaued.
