Question

What’s the ‘need’ for the stock prices to change every minute?

Answer 1

Too many people and too many stocks. If there were only two people who wanted to trade the only stock, you could probably get by with setting the price once a day. With automated trades, I wouldn’t be surprised if stock prices were changing every nanosecond.
