Not sure if I'd trust Disney's forward P/E guidance until we see actual performance to back it up -
Disney+ has been a money sink and there's still a significant risk of faster cord cutting harming earnings faster than Disney+/Hulu/ESPN+ growing profitability.
I think the $60B investment might be dragging down the stock valuation for the time being until some return is seen on it. Right now that's a $60 billion liability on the balance sheet. When/if park visitor spending goes up after the investment starts, numbers will be a little more solid and investors might give Disney the benefit of the doubt.
