We’ve rounded up the latest aftermarket movers

The after-market movers are stocks that change hands after the normal market closes. As the major U.S. stock exchanges close, the after-hours market opens at 4 p.m. U.S. EDT. Even though after-hours trading can extend until 8 p.m., the volume of after-market movers tends to fade much earlier. During after hours, trades are conducted over electronic communication networks (ECNs).

Traders and investors can use after-market movers when news breaks after the stock exchange close. Earnings announcements, for example, may cause aftermarket movers to act.

A spike in volume may occur when a piece of news is released, but it usually fades as the session progresses. After six o’clock, the volume of trades usually drops significantly. After-hours trading is risky for stocks that are illiquid.

While during normal business hours billions of shares are traded, after-hours trading is just a fraction of that volume. Does it make sense to trade in an after-hours market? Maybe, but you have to do some research first.
