A decisively bullish week, driven by earnings season: most of the flagged premium went into calls swept at the ask, much of it on names reporting within days. Every trade below cleared the same bar our live flow feed applies: aggressive ask-side execution and verified order sides.

The Week's Top Flow
$12.8M Microsoft call sweep
The largest print of the week: $12.8M in $MSFT calls expiring September 2026 (36 days out), swept at the ask on Thursday and flagged live on X as it hit the tape. Break-even sits at $477.90, roughly a 6% move higher by expiration.
$4.9M Corning bet on earnings morning
$4.9M in $GLW calls with 52 days to expiry, swept at the ask on Tuesday and flagged live on X hours before the company reported earnings. Ask-side sweeps into an earnings print are among the most aggressive positioning we track.
$2.7M SanDisk calls, backed by the dark pool
$2.7M in $SNDK calls expiring February 2027, swept at the ask on Thursday and backed by a $21.5M block in SanDisk's dark pool the same session alongside converging bullish signals. Long-dated calls plus size in the dark pool is the convergence pattern we weight most heavily, and this one was flagged live on X the moment it converged.
Strategy Corner
The week's standout multi-leg position was a $69.2M $SNDK put credit spread: sold the Jan $1200 puts, bought the Jan $1000s for a net credit. It is a bullish income position that keeps the premium collected as long as SanDisk holds above $1200, about 10% above the price at entry, with risk capped at the $1000 strike. The position holds through the Aug 5 earnings report.
Runner-up: a $40.7M $MSTR call spread (bought the Aug $95s, sold the Aug $125s) paying up to 4.2x its cost if MicroStrategy climbs 31% by Aug 21, held through the Jul 30 earnings report.

How Last Week's Flags Resolved
We score every flag and delete nothing. From the Jul 24-30 cohort:
- $CORZ 09/18 $18C · stock +11.2%, option +79.9%
- $BRUN 11/20 $20C · stock +8.4%, option +57.1%
- $SIMO 08/21 $240C · stock +6.9%, option +53.2%
14 of 39 flags closed green the next session. Keep in mind that next-session scoring is the strictest possible window: many of the positions we flag are longer-dated, like the February 2027 SanDisk calls above, and are built to play out over weeks or months rather than pay off overnight. Institutions accumulating ahead of a catalyst rarely need the very next candle to go their way. Flow shows you where they are positioned; it is not a guarantee of direction, and we publish the full scoreboard either way.
The Week Ahead
Earnings from Berkshire Hathaway (Mon), AMD (Tue), and Eli Lilly (Wed), with 639 more names on the calendar. Also on watch: an FDA decision for Moderna expected Wednesday. When flow starts printing against these events, it hits the live feed first, and you can track dealer positioning into the prints with gamma exposure.
