Current GREK snapshot
As of May 15, 2026, spot at $70.87, ATM IV 27.70%, IV rank 52.28%, expected move 7.94%. The butterfly on GREK 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 GREK specifically: GREK IV at 27.70% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 7.94% (roughly $5.63 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 GREK expiries trade a higher absolute premium for lower per-day decay. Position sizing on GREK should anchor to the underlying notional of $70.87 per share and to the trader's directional view on GREK etf.
GREK butterfly setup
The GREK 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 GREK near $70.87, the first option leg uses a $67.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GREK 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 GREK shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $67.00 | $4.55 |
| Sell 2 | Call | $71.00 | $2.15 |
| Buy 1 | Call | $74.00 | $1.03 |

When traders use butterfly on GREK
Butterflies on GREK are pinning bets - traders use them when they expect GREK 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.
GREK thesis for this butterfly
The market-implied 1-standard-deviation range for GREK extends from approximately $65.24 on the downside to $76.50 on the upside. A GREK long call butterfly is a pinning play: it pays maximum at the middle strike if GREK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current GREK IV rank near 52.28% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on GREK should anchor more to the directional view and the expected-move geometry. As a Financial Services name, GREK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GREK-specific events.
GREK 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. GREK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GREK alongside the broader basket even when GREK-specific fundamentals are unchanged. Always rebuild the position from current GREK chain quotes before placing a trade.
