Discover — MBLY +15.78% (4:30 PM ET)

MBLY surges +15.78% in after-hours trading, one of the sharpest post-close moves on tonight's market-wide scan.

MBLY closed the regular session at $8.30 and is now printing $9.68 in after-hours, a move of roughly $1.38 per share on $12.7M in dollar-volume — meaningful size for an extended-hours tape. This name carries no internal fundamental coverage on our end, so we're flagging it purely on price and volume action: the magnitude of the move and the capital behind it are what earned it the lead slot tonight. Watch whether $9.68 holds as a floor or acts as a spike high when the overseas sessions open — how it behaves around that level will be the first tell on whether this has continuation into Wednesday's cash open.
