RE: After hours trades27 Nov 2019 21:14
With regard to the other matter :-
The same things that move stock prices during regular hours also move them after hours β supply and demand. If big news about a company breaks, that will affect the price in after-hours trading, and the price will rise or fall depending on the news. When the stock opens in the morning, traders will be taking into account the news, as well as the after-hours reaction to it, and that may affect the opening price.
