I am naive here, can someone explain what is the economic utility of a stock market ?
For example, its easy to understand utility of food, cloths, car, house, money. But I am not able to find a reason about stock market existence for day-to-day trading, where secondary stocks are traded daily after IPO. It seems none of the day-to-day trading money/profit ever goes back to business to help them to improve that business.
The answer is that the casino-like activity of the secondary market provides a great incentive to companies to primary-list. This engine drives business formation through the valuations it can provide to companies. And companies can issue more shares to raise more capital from the very liquid casino. So it's helpful in that way.
The utility comes from the utility of having the chance to sell your IPO shares on the day and date of your choosing. That liquidity makes the shares more valuable to the buyer, who might find herself in a "oops I have to sell now" situation.
