Is TKO Stock Really Expensive?

Shares of TKO Group Holdings (TKO) trade at 56.8 times its earnings over the past twelve months, compared with 22.9 for the S&P 500. Buyers paying that much are betting on profit the owner of UFC and WWE has not earned yet, and its long media deals may be what they are counting on. So how fast would TKO have to grow for its share price merely to hold.
