Flow Movers : July 18, 2026 • Prices as of July 19, 2026
Yesterday’s bullish options flow is delivering strong results, with the average up 14.7% and all 15 names in positive territory, led by BFLY’s explosive 55.9% gain and solid momentum from semiconductor plays like SOXL and SNDK. The bearish names are holding their short thesis as well, with all 15 tracking lower and averaging a 3.2% decline, though the losses are more modest than the bullish side’s gains. The asymmetry suggests yesterday’s call buying had better conviction than the put positioning.

I will be posting this report every week day going forward at around noon for paying Subscribers. Note that BFLY was high lighted as a Rarity Name in my morning brief yesterday:
Unusual Activity
🔔 BFLY
Calls Bought · Strike: 10.0 · Exp: Aug26 · 4000 contracts · $274K
Big size on the Aug26 10 calls, 4000 contracts, looking for a real move off a low-priced name. The chart is constructive with price riding above a rising 8 EMA at 5.85 and the full stack pointed up. As long as it holds the 21 at 5.25 the momentum stays intact.
Butterfly Network (NYSE: BFLY) is a medtech company that develops handheld, semiconductor-based ultrasound devices and AI-powered software under its Ultrasound-on-Chip platform. The company operates across three growth vectors: its core iQ probe line sold into hospitals and health systems, a Compass AI enterprise software layer, and a Butterfly Embedded licensing business that co-develops its chip technology into third-party products. The stock is up sharply on June 18, 2026, with shares trading near $7.47 - a roughly 26% single-session move - driven by back-to-back investor conference appearances and momentum around its AI ultrasound ecosystem narrative.
Crime signal: MEDIUM — Q2 2026 earnings are estimated around July 31, 2026 - squarely within the August expiration window - and the flow arrived on a day of active management investor meetings at a TD Cowen conference, creating a narrow window where forward guidance color shared in one-on-ones could theoretically inform aggressive directional positioning ahead of the print.
