The pros will be prosThe pros know exactly how to play ENB when ENS does a RAISE. They take the share price of ENB down at the start of the week following the announcement to grab shares from retail investors that don't know what is going on and then they ramp the ENB share price back up later in the week knowing that Middlefield will be buying more than a million shares (about $50 million worth).
I don't expect retail investors to play the games that the pros play. After all, the pros take advantage of inefficiencies in the market to make a living and us retail investors are just spectators. However, if you understand the game, you can plan accordingly which makes it less likely that you will be a victim.
