I did both, covered some hedge and bought the dip. I usually don't come on the trading community when trading as I need to execute my plan. I do the planning when markets are closed. A lot of opportunity in that premarket on both sides to capture. And I need to capture that. 

I can read all the opinions, prognostications, and news after. My experience is that it is just part of the movie, usually a distraction, too much bias, and can cause a mistake if I spend too much time around it. The market is down 0.32% currently from yesterday's close for context. Currently at 4,063 after yesterday's higher high at 4,100 and close at 4,076. Perspective.  It also held the 200 day as support. I'l change if/when the market changes. My bias is making money, I'm not a bull or bear..I'm opportunistic. 

The market, whoever runs it, I call them "Oz" makes the rules. I just take what is given when it is given.
