MTG Butterfly Strategy
MTG (MGIC Investment Corporation), in the Financial Services sector, (Insurance - Specialty industry), listed on NYSE.
MGIC Investment Corporation, through its subsidiaries, provides private mortgage insurance, other mortgage credit risk management solutions, and ancillary services to lenders and government sponsored entities in the United States, Puerto Rico, and Guam. The company offers primary mortgage insurance that provides mortgage default protection on individual loans, as well as covers unpaid loan principal, delinquent interest, and various expenses associated with the default and subsequent foreclosure. It also provides contract underwriting services, as well as reinsurance.

MGIC Investment Corporation was founded in 1957 and is headquartered in Milwaukee, Wisconsin.
MTG (MGIC Investment Corporation) trades in the Financial Services sector, specifically Insurance - Specialty, with a market capitalization of approximately $5.45B, a trailing P/E of 7.76, a beta of 0.71 versus the broader market, a 52-week range of 24.78-29.97, average daily share volume of 2.1M, a public-listing history dating back to 1991, approximately 555 full-time employees. These structural characteristics shape how MTG stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.71 places MTG roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 7.76 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. MTG pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on MTG?
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.
Current MTG snapshot
As of May 15, 2026, spot at $25.93, ATM IV 14.90%, IV rank 4.61%, expected move 4.27%. The butterfly on MTG below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this butterfly structure on MTG specifically: MTG IV at 14.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a MTG butterfly, with a market-implied 1-standard-deviation move of approximately 4.27% (roughly $1.11 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MTG expiries trade a higher absolute premium for lower per-day decay. Position sizing on MTG should anchor to the underlying notional of $25.93 per share and to the trader's directional view on MTG stock.
MTG butterfly setup
The MTG 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 MTG near $25.93, the first option leg uses a $24.63 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MTG chain at a 34-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 MTG shares for the stock leg in covered calls and collars).

| Buy 1 | Call | $27.23 | N/A |

When traders use butterfly on MTG
Butterflies on MTG are pinning bets - traders use them when they expect MTG to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
MTG thesis for this butterfly
The market-implied 1-standard-deviation range for MTG extends from approximately $24.82 on the downside to $27.04 on the upside. A MTG long call butterfly is a pinning play: it pays maximum at the middle strike if MTG settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MTG IV rank near 4.61% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on MTG at 14.90%. As a Financial Services name, MTG options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MTG-specific events.
MTG 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. MTG positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MTG alongside the broader basket even when MTG-specific fundamentals are unchanged. Always rebuild the position from current MTG chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on MTG?
- A butterfly on MTG is the butterfly strategy applied to MTG (stock). 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 MTG stock trading near $25.93, the strikes shown on this page are snapped to the nearest listed MTG chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are MTG butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the MTG butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 14.90%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a MTG butterfly?
- The breakeven for the MTG butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current MTG market-implied 1-standard-deviation expected move is approximately 4.27%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
