SeaWorld Entertainment's public image has already come under attack due to alleged mistreatment of killer whales. Now, the company's stock is also being put through the wringer. Should investors hang on for the ride or get out?

SeaWorld shares plunged 35 percent in late trading Wednesday after the company missed second-quarter earnings estimates and projected a decline in revenue for the full year. The company pointed to a number of issues, including new openings at competing parks and a delay in the debut of one of its own attractions.
