Re: LMGTFY
Haven't traded myself for a few years now, but aftermarket trading was a sort of wild-west thing - not many players, low liquidity, which can lead to "interesting" price moves that aren't later confirmed in the normal markets. That can work for you or against you as a trader if you know that and get kind of a feel for it.
Or used to.
For example, sometimes there are no buyers for something - and a dumb seller puts out a "sell at market" order. If you had a "buy at 1/2 the normal price or below" order in - you'd get a steal, one you could probably sell at something like the normal price the next day...and other variations of that kind of thing on either side of a trade.
Nowadays, the HFTs (who never sleep) and a few savvy humans (who never seem to need sleep)...kinda wrapped that one up, leaving little for the average person to play with there.
Price moves after hours are generally not as meaningful as those that occur with real volume behind them - they can be a complete illusion that will lead one astray if one things the moves are going to hold or continue the next day. It's kind of a "selected from random data" thing - prices are mostly set by uninitiated out-of-the-know small traders - it can go either way as to what's going to happen next in the "real" markets.
So, it's a possible indicator but that's all - the wind may change direction at any time...
