how does the market decide?
not 100% cuz there are many things that reflect the price.
usually it about the profits made by that company, and the likeness of growth.
also debts they currently hold, mergers they recently made, number of employees they have. million things.
say you are going with the NASDAQ exchange, they may decide your company is worth 3 bucks a share. no debate lol. you dont have much choice really.
but if a company is likely to ever join the market, they dont usually wait till they would have opening stock of 50bucks a share. cuz that wouldnt promise much hype and buy in, and it would actually hurt the value a lot lol.
