SPY M5: 2.5M shares changed hands at the close, buyers came in strong in the last 10-15 seconds or so, price barely moved down. 'may be some profit taking overnight, we'll see if the squeeze up resumes in the morning - I'm expecting institutional participation to be even lower tomorrow, making it a 4 day weekend for those institutional traders that otherwise stuck the week out while the "bosses" were gone for a few weeks. Will volume taper off into the close or will retail fill in. Time will tell. Hope you all made money today.
