Today’s TellStandout single-name positioning

Quiet Tape

No standout single-name positioning today.

Flow distributed evenly across index products. No single ticker accumulated the kind of one-sided ask-side imbalance or concentrated dark-pool absorption that draws institutional attention. Tape stayed in observation mode.
