Is this lottery like stock market?
Theoretically, the fair value of a company is based on its earnings prospects (or its expected dividends, which is related to earnings). Since not everyone agrees on those prospects, and technical issues hit (investors need to sell for some reason), stock prices fluctuate. However, the fundamental value of a company is relatively stable from day-to-day, regardless of the volume of trading. This valuation stability is quite different from your proposed lottery system, where the value is entirely based on previous purchase volume.
