$RARE afterhours Sep 02, 2026

$RARE -45.16% — what the base rate says

The Boss FILTRIX Market Desk

Wednesday evening tape serves up two contrasting realities. On the gainer board, $TLYS rips 31.76% into the close with zero news, while $NYXH climbs 15.89% after reporting its clinical trial met primary endpoints. On the other side of the tape, $MEI dumps 19.78% following its Q1 financial report, and $RARE collapses 45.16% without a headline in sight.

Retail loves to treat every mystery green candle as a breakout. Across 2,796 historical instances of low-float, no-news gap-ups of 30% or more, the setup fades to red 70% of the time with an average intraday return of -3.82%.

Hope is loud in after-hours. The base rate is completely silent.
