Six Flags Entertainment Corporation shares dropped more than 8.5% in overnight trading following a fatal incident involving the Goliath roller coaster at Six Flags Over Georgia. Reportedly, one visitor was killed and four others were injured, prompting the company to temporarily close Goliath along with eight similar attractions across the Company's other amusement parks. The stock continued to decline throughout the day and by midday had fallen to a more than 15% decline. This incident follows the permanent closure of the X2 rollercoaster last month after a CNN investigation and subsequent lawsuits alleged riders suffered injuries on the coaster.
