SPY "Glitch"? Someone needed $6M in help

SPY closes today at $567.13, but 6 minutes after close (4:06 PM ET) 2 SPY blocks trade at $586.86 (+$19!). Volume on the first block is 250k followed very quickly by a 50k block at the same $586.86 price.

Literally seconds later, a 300k block of SPY trades at $566.86.

Someone netted $6 MILLION right after market close by selling 300k SPY at $586.86 and, within the same minute, buying back 300k SPY for $566.86.

👃 CRIME! COLLUSION! DESPERATION!

Today is exactly 1 Margin Call (T15+C14) from when XRT finally got off RegSHO Threshold List [SuperStonk] where this sub has been tracking XRT shenanigans.

EDIT: Alternative title could've been "this is how you transfer funds to a co-conspirator".
