Hi, I'm new here and was wondering if anyone could help me with understanding something I observed yesterday in a chart of SONS. During the last few minutes of trading the price dropped significantly with a surge in volume relative to the whole day. Then in the after market and today the price popped back up to the price before the drop. Is this because of the market makers playing some tricks to drop the price on a huge sell order so they can get in and later sell those shares when the price reaches and equilibrium again? Any help would be appreciated. Thanks!
