What is a butterfly on TRST?
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 TRST snapshot
As of June 29, 2026, spot at $54.36, ATM IV 51.70%, IV rank 23.69%, expected move 14.82%. The butterfly on TRST 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 18-day expiry.
Why this butterfly structure on TRST specifically: TRST IV at 51.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a TRST butterfly, with a market-implied 1-standard-deviation move of approximately 14.82% (roughly $8.06 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TRST expiries trade a higher absolute premium for lower per-day decay. Position sizing on TRST should anchor to the underlying notional of $54.36 per share and to the trader's directional view on TRST stock.
TRST butterfly setup
The TRST 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 TRST near $54.36, the first option leg uses a $51.64 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TRST chain at a 18-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 TRST shares for the stock leg in covered calls and collars).

When traders use butterfly on TRST
Butterflies on TRST are pinning bets - traders use them when they expect TRST 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.
TRST thesis for this butterfly
The market-implied 1-standard-deviation range for TRST extends from approximately $46.30 on the downside to $62.42 on the upside. A TRST long call butterfly is a pinning play: it pays maximum at the middle strike if TRST settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current TRST IV rank near 23.69% 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 TRST at 51.70%. As a Financial Services name, TRST options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TRST-specific events.
TRST 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. TRST positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TRST alongside the broader basket even when TRST-specific fundamentals are unchanged. Always rebuild the position from current TRST chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on TRST?

With TRST stock trading near $54.36, the strikes shown on this page are snapped to the nearest listed TRST chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are TRST butterfly max profit and max loss calculated?
