Nighttime futures seem to be overreacting lately

Since the nighttime futures dropped by more than 25 points last Friday,
I bought one. I felt the drop was somewhat excessive due to the disappointment regarding Samsung Electronics' shareholder return policy, so I figured that as long as the US market doesn't crash significantly, I would make at least a 10-point profit when the main market opens on Monday.
The futures price that just started is 1092, which is up 18 points from Friday's nighttime level of 1074.
