The reverse mask closes the week. Indexes red — Dow -0.23%, $SPY -0.25%, $QQQ -0.44% — but breadth 1.09x positive. More names advancing than declining, yet volume 0.77x sell-biased. The money flows down while the names tick up. Q3's defining divergence persists.

Nasdaq exactly 1.00x. Perfect parity. The mega-cap tech names selling the index are perfectly offset by the rest of the Nasdaq advancing. The tension is visible in a single number.

AMEX 1.45x — small caps strongest exchange. Yesterday: $IWM +$243M dark pool buy. Today: AMEX leads with the strongest reading of the week. The large-to-small rotation continues, confirmed across every data source.

The week in five masks. Monday flat. Tuesday reverse mask. Wednesday original mask (CPI inline). Thursday concentrated (PPI benign, volume green, breadth red). Friday reverse again. Five sessions, five variants. The mask changed form every day but never disappeared.

The dark pool sold the indexes two consecutive sessions into rallies (Wed -$983M, Thu -$2.18B). The dark pool bought $IWM and $INTC. Today: $GOOGL $172.5M dark pool buy at 12:09 PM — re-entering a name it exited.

The tape into the close matters. The rotation is confirmed. Watching.
