CMAG Butterfly Strategy
CMAG (Corgi ETF Trust I - Corgi Mag 7 ETF), in the Financial Services sector, (Asset Management industry), listed on CBOE.
CMAG seeks capital appreciation through concentrated exposure to the seven mega-capitalization companies known as the Magnificent Seven: Alphabet, Amazon, Apple, Meta Platforms, Microsoft, NVIDIA, and Tesla. The market cap-weighted portfolio consists of US-listed common stocks. The actively managed fund may also obtain exposure through economically similar instruments, including depositary receipts and derivatives, such as swap agreements and forward contracts, to manage cash flows or facilitate portfolio transitions. CMAG may treat an issuer's successor following reorganization, merger, name change, or similar corporate action as the applicable Magnificent Seven company. The fund may hold cash, cash equivalents, or short-term US Treasuries for liquidity and portfolio management.

These structural characteristics shape how CMAG stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 2.41 indicates CMAG has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position.
What is a butterfly on CMAG?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
CMAG snapshot
As of September 29, 2026, spot at $26.77, ATM IV 37.60%, expected move 10.78%. The butterfly on CMAG below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 17-day expiry.
Why this butterfly structure on CMAG specifically: IV rank is unavailable in the current snapshot, so regime-based timing for CMAG is inferred from ATM IV at 37.60% alone, with a market-implied 1-standard-deviation move of approximately 10.78% (roughly $2.89 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CMAG expiries trade a higher absolute premium for lower per-day decay. Position sizing on CMAG should anchor to the underlying notional of $26.77 per share and to the trader's directional view on CMAG stock.
CMAG butterfly setup
The CMAG butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CMAG at $26.77 on that close, the first option leg uses a $25.43 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CMAG chain at a 17-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 CMAG shares for the stock leg in covered calls and collars).

CMAG thesis for this butterfly
The market-implied 1-standard-deviation range for CMAG extends from approximately $23.88 on the downside to $29.66 on the upside. A CMAG long call butterfly is a pinning play: it pays maximum at the middle strike if CMAG settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Financial Services name, CMAG options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CMAG-specific events.
CMAG butterfly positions are structurally neutral / pin (limited-risk, limited-reward); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. CMAG positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CMAG alongside the broader basket even when CMAG-specific fundamentals are unchanged. Always rebuild the position from current CMAG chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on CMAG?

The strategy is structurally neutral / pin (limited-risk, limited-reward): A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration. With CMAG stock at $26.77 on the most recent close, the strikes shown on this page are snapped to the nearest listed CMAG chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are CMAG butterfly max profit and max loss calculated?
