Squeeze Report — July 28, 2026
Today's book is dominated by pre-earnings tension, with 18 of 24 names reporting within two weeks. The standout setups are GRPN's extreme 66.7% short interest ahead of its AI-restructuring update and NTST's 22-day cover facing mechanical index buying, while the biotech cluster shows elevated risk from dilution and fading sector momentum.
