Any idea what is happening with the last minute big buys during the last few minutes of the market? Today it went from 11.6 to 12.10 in the last 5 minutes on what looked like a block of 120,000 shares. Yesterday it was 11.6 to 12.35 in last few minutes, and the day before from 11.7 to almost 12.20. All times on big block trades and all 3 in like the last 3 minutes. Then immediately after the close it is down by about the same amount.
I'm fairly new to watching the market but this seems to be a very odd pattern.
