What is a butterfly on QSI?
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 QSI snapshot
As of May 15, 2026, spot at $0.89, ATM IV 92.96%, IV rank 17.19%, expected move 26.65%. The butterfly on QSI 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 28-day expiry.
Why this butterfly structure on QSI specifically: QSI IV at 92.96% is on the cheap side of its 1-year range, which favors premium-buying structures like a QSI butterfly, with a market-implied 1-standard-deviation move of approximately 26.65% (roughly $0.24 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated QSI expiries trade a higher absolute premium for lower per-day decay. Position sizing on QSI should anchor to the underlying notional of $0.89 per share and to the trader's directional view on QSI stock.
QSI butterfly setup
The QSI 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 QSI near $0.89, the first option leg uses a $0.85 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed QSI chain at a 28-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 QSI shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $0.85 | N/A |
| Sell 2 | Call | $0.89 | N/A |
| Buy 1 | Call | $0.93 | N/A |

When traders use butterfly on QSI
Butterflies on QSI are pinning bets - traders use them when they expect QSI 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.
QSI thesis for this butterfly
The market-implied 1-standard-deviation range for QSI extends from approximately $0.65 on the downside to $1.13 on the upside. A QSI long call butterfly is a pinning play: it pays maximum at the middle strike if QSI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current QSI IV rank near 17.19% 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 QSI at 92.96%. As a Healthcare name, QSI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to QSI-specific events.
QSI 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. QSI positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move QSI alongside the broader basket even when QSI-specific fundamentals are unchanged. Always rebuild the position from current QSI chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on QSI?
- A butterfly on QSI is the butterfly strategy applied to QSI (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 QSI stock trading near $0.89, the strikes shown on this page are snapped to the nearest listed QSI chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are QSI 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 QSI butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 92.96%), 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 QSI butterfly?
- The breakeven for the QSI 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 QSI market-implied 1-standard-deviation expected move is approximately 26.65%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
