What is a butterfly on SK?
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.
SK snapshot
As of September 29, 2026, spot at $28.76, ATM IV 108.00%, expected move 30.96%. The butterfly on SK below is built from the September 29, 2026 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 SK specifically: IV rank is unavailable in the current snapshot, so regime-based timing for SK is inferred from ATM IV at 108.00% alone, with a market-implied 1-standard-deviation move of approximately 30.96% (roughly $8.90 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 SK expiries trade a higher absolute premium for lower per-day decay. Position sizing on SK should anchor to the underlying notional of $28.76 per share and to the trader's directional view on SK etf.
SK butterfly setup
The SK butterfly below is built from the September 29, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SK at $28.76 on that close, the first option leg uses a $27.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SK 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 SK shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $29.00 | $2.68 |
| Buy 1 | Call | $30.00 | $2.20 |

When traders use butterfly on SK
Butterflies on SK are pinning bets - traders use them when they expect SK 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.
SK thesis for this butterfly
The market-implied 1-standard-deviation range for SK extends from approximately $19.86 on the downside to $37.66 on the upside. A SK long call butterfly is a pinning play: it pays maximum at the middle strike if SK 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, SK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SK-specific events.
SK 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. SK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SK alongside the broader basket even when SK-specific fundamentals are unchanged. Always rebuild the position from current SK chain quotes before placing a trade.
