Your numbers are completely wrong...apple just had $50B in revenue for its weakest quarter...last quarter they had $60B and in their strongest quarter Q4 they had $89B pre trump tax cuts. If their current growth rate stays the same Apple will hit $280B revenue and $65B in profits.

I’m not sure how you are calculating equity but they have $240B in plain cash. They have so much in IP, and extremely low interest loans.

Market cap does mean something, it’s literally the most meaningful value the world puts on a company
