$KPTI premarket Jul 31, 2026

$KPTI -71.47% — what the base rate says

The Boss FILTRIX Market Desk

Let's settle the score first: Yesterday we warned about $MGRX. It opened at 0.42 and dumped to 0.2936, closing -30% red. Process over outcome, but the outcomes sure like the process.

Today's main attraction is Focus Universal ($FCUV), up 378% on absolutely zero news. It is a $1M market cap company with a tiny 2 million share float.

When a micro-cap gaps up over 30% with no news, retail sees "to the moon." Our database sees a different story. In 2,411 historical instances of this exact setup, the stock closed red 70% of the time, with a median intraday return of -10.49%.

Translation: the house wins 7 out of 10 times against the chasers. If you are buying the pre-market high here, you are providing the liquidity for someone else's exit.

Keep your hands in your pockets.
