What happened

Six Flags (FUN) stock fell more than 10% after hours on Monday from a $11.92 close after a guest died on its Goliath roller coaster in Georgia, leading it to close similar rides. One person died and several others were hurt on the 200-foot ride shortly before 4 p.m., and police are investigating. Six Flags said it is cooperating and has temporarily closed similar rides at other parks. Early trading after the market closed showed a smaller 8.8% drop, to $10.87, while later reports put it above 10%. The shares had closed up 4.5% that day.

Why it matters

Six Flags depends on guests feeling safe, so a death on a major ride can hurt visits, and the company has already closed similar rides elsewhere. The stock was already down about 22% this year, and the new drop leaves it near its 52-week low of $10.45. Six Flags also faces earlier injury lawsuits tied to its X2 coaster in California.
