It is, really, a global marketplace. You go and you can buy and sell the company's shares. You get to own a piece of them while creating wealth. It's like any other marketplace where people trade ownership in companies-from high-tech giants to energy providers-and with each stock you buy, you're essentially buying into this entity and hoping it will ultimately grow.The stock exchange operates between defined time periods, roughly between 9:30 A.M. and 4 P.M. (if not for the exchange), and it becomes crucial for traders to be well informed about the trading timings at their location.
