EWZ Bull Call Spread — 2026-08-21

EWZ (iShares MSCI Brazil ETF) shows bullish unusual options activity: $1865K of buyer-initiated unusual call flow (100% call-dominant) detected across near-term expirations, with a peak vol/OI ratio of 0.3x on the 37 call. IV rank is 41 (moderate) — a bull call spread (35.5/36) trims theta/vega bleed versus a naked long. Buy the $35.5 / sell the $36 call bull call spread expiring 2026-08-21 (23 DTE) for a net debit of $0.24 ($24 per spread). Breakeven at $35.74; net delta 0.08.

Underlying: EWZ @ ~$35.51 | 2026-08-21 (23 DTE) | Net debit (entry): ~$24 per spread. Use limit orders at the mid or slightly worse.

MAX LOSS: Limited to the net debit ($24 per spread). Max gain is capped at the strike width minus the debit — a defined-risk, defined-reward trade. | IV RISK: IV rank is 41 — reasonable for a debit spread. | TIMING: 23 DTE — unusual flow is a near-term signal; act promptly or the setup may stale. Close or take profit before expiration week to avoid gamma risk. | SECTOR: EWZ is in Other — avoid concentration with other open Other positions. | EXECUTION: Use limit orders at mid or slightly worse on the spread (don't leg in). Verify the bid-ask before sending; do not chase with market orders. | EVENTS: Check for upcoming earnings, FDA decisions, or macro prints within the trade window that could cause outsized gap risk.
