How is the quantity of a company’s stocks tracked?

Question

There is a specific number of stocks for each publicly traded company, right? With all the avenues of trading, how are there never shortages of a stock?

In: Economics

Answer 1

There’s never any shortages because someone is always selling. If nobody was selling but people wanted to buy prices go up until people are enticed to sell. Demand for the stock sets its prices after IPO.
