The P/E ratio for a company steadily growing at ~10% should be around 20. A rapidly growing company might warrant a much higher P/E. If I expect your company to be 30x as large in a decade as it is now, then maybe a P/E ratio around 600 makes more sense.
If your company is steady or declining, a lower P/E makes more sense - maybe something around 10.
Apple is at best in the steady 10% growth category. There's a lot of evidence that Apple is going to start contracting, though. They've stopped disclosing sales numbers, because they peaked years ago on most product lines. They've been jacking up prices to maintain revenue, but at some point this strategy will fail and revenue from iPhone and Mac will tumble. The AirPods and Apple Watch are still growing, but for how long? Plus they're much smaller markets and go for much lower prices than the iPhones and Macs that they're supposed to make up for.
Services is another big market for Apple, but their biggest service, the App Store and In-App Purchases, are increasingly under fire for being a monopoly.
Apple's time at the top is coming to an end. Tim Cook milked the brand for a long time, but it's coming to an end.
You are so wrong. The market cap today is 2.12 trillion. The services side alone is a trillion dollar company and the hardware side is as well. It predicted 30% of iPhone user will upgrade when the 5g phones come out. The app store is bs, will never amount to anything.
