Why is Six Flags Entertainment stock climbing today?

Six Flags Entertainment (FUN) stock rose 1.1% to $12.44 in pre-market trading after activist hedge fund Jana Partners, holding a 9% stake, urged the board to hire an investment bank and explore a potential sale, citing disappointing Q2 results. The broader market had minimal impact, and sector peers showed no new catalysts. FUN has lost over half its value from its 52-week high of $27.37.
