If I sell 100 lemonades per day and can't pay my rent, yet my neighbor sells 50 lemonades but manages the business in a way to pay his rent and a salary, how can my business possibly be more valuable? It's a silly example but I don't think it's far fetched. Similarly, Apple is worth far more than 20% of the phone market despite having a grasp on only 20% (give or take, I don't recall the exact number) market shares. There's a reason companies aren't valued based on revenue.

But its definitely not in any financial metrics. If you own walmart for a year, you'll make around 4 billion, while if you own Google, you'll make around 7. And Google is likely going to be growing faster than Walmart.
