The SPY Gap up is a big surprise to me, but it is good one, and I love it.
Technically, it is a little bit over-bought in the past 3 days, so I just sold about 50% of my SPY positions. But loaded about 10% of short position of SPY just to hedge the over-bought risk in case.
If market goes within what I am expecting now, i.e. market will pull back about 1% in the next 2 to 3 days, I am going to cover my short positions.
The long position SPY will likely go to my initial target around 436 in the coming weeks.
Good luck.
