$SXTC -33.88% — what the base rate says

Bluejay Diagnostics ($BJDX) is trading up 34.00% after-hours on absolutely nothing. No filings, no PR—just an $890k micro-cap with a 1M share float being tossed around in the dark.

Retail sees the flashing green and feels the itch. But the historical database paints a grim picture. Across 2,411 instances of a low-float stock gapping up over 30% on no news, the stock closes red 70% of the time, with a median intraday return of -10.49%.

Compare that to Teradata ($TDC), which dropped 17.56% after-hours on real, tradeable earnings data, or Digital Turbine ($APPS) up 17.14% on actual guidance upgrades.

Let the gamblers chase the vapor. Close the laptop and journal the day.
