Artists don't compare themselves to each other based on money. Nobody really knows what money other artists have. They don't care that much. The measure is the work and how you think your work is perceived. How the museums are. How you are doing.
I don't think anybody ever makes any money buying and selling stock. They have to make money by keeping the stock.
