SPX short setting up

S&P500 is getting a little bit overextended here. I expect a selling pressure around 4200 level or off the trend line resistance we've been tagging last couple months. Could be a profit taking into a close today before weekend.
I wouldn't be surprised to see us come back down to retest 4000 level or at least close the gap at 4020 next week. This is lining up a potential short opportunity. Wait for a weakness before attacking.
