While I've not specifically considered stocks with or without activity during post and pre market, I'm coming around to resent that trading period which, at times, dramatically impacts a stock price. Examples are many, from AMZN's recent 300 drop in post market trading, BABA's significant climbs and drops at 4 am, etc. I'm a big proponent of 24/7 trading, to give those in other time zones the opportunity to trade just the same. We'd see big shifts in trading activity, starting with East/West coasts but also from Asian time zones, from India to Japan, where most of the world resides and where gambling is a societal addiction. However, today's trading hours are left to brokerages' discretion and there doesn't seem to be a rule as to which stocks are available to trade off market hours. While I continue to trade some stocks off hours, I'm becoming more careful to pick volatile stocks that I can buy and sell during my broker's operating hours. Any thoughts on that?
Without off hours trading the price would see a dramatic impact anyway reflected in the opening auction.
We need more competition between exchanges, to bring about a true 24x5 week, (excluding those oddball countries that are open Sat or Sun), but the way things are going they are consolidating more and more.
Saudi Arabia, 9th largest in the world, trades on Sun to Thu. https://www.saudiexchange.sa/ There are others as well in Bahrain, U.A.E., Jordan etc.
Really? What happens at 9:30 am and 4:30 pm east coast time? Now remove it… that’s the goal. Removing these pressure points allows anyone from anywhere around the world to trade anytime without concerns for the effects of opening or closing market.
It is not open Saturday but is open in Sunday. I was asking about any countries trading on Saturday OR Sunday, not Saturday AND Sunday.
