Anyone knows? Not just ETFC. Other stocks' afterhour quotes are high, too.
trades hit the tape after hours that were executed during the trading session. Sort of a house cleaning. The bid/ask is all that is important.
Because the after hours market is not liquid. Very few buyers & sellers, lack of information. It's risky business. So if you really want to buy in after hours, you will pay more. Never, ever, place a Market Order after hours, stick to limit orders.
