$TNON premarket Aug 20, 2026

$TNON -34.44% — what the base rate says

The Boss FILTRIX Market Desk

A $4M freight-shipping micro-cap named $SGLY is gapping +121% pre-market because it signed a "non-binding" framework for a 900-acre AI data center. That PR hit right on the heels of a $1.8M registered direct offering.

Across the ticker, $AAP drops -23% on real Q2 numbers, while $HUIZ rips +131% on unaudited H1 results.

Across 2,881 historical catalyst gap-ups over 30%, the base rate shows 65% fade into the close with an average intraday loss of roughly 3%. When the PR is non-binding and the dilution is already filed, retail is simply buying the exit.
