Great Southern Bancorp, Inc. was founded in 1923 and is headquartered in Springfield, Missouri.
GSBC (Great Southern Bancorp, Inc.) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $739.8M, a trailing P/E of 10.47, a beta of 0.52 versus the broader market, a 52-week range of 53.76-70.91, average daily share volume of 86K, a public-listing history dating back to 1989, approximately 882 full-time employees. These structural characteristics shape how GSBC stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.52 indicates GSBC has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 10.47 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. GSBC pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on GSBC?
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 GSBC snapshot
As of May 15, 2026, spot at $67.48, ATM IV 36.00%, IV rank 11.01%, expected move 10.32%. The butterfly on GSBC 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 GSBC specifically: GSBC IV at 36.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a GSBC butterfly, with a market-implied 1-standard-deviation move of approximately 10.32% (roughly $6.96 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 GSBC expiries trade a higher absolute premium for lower per-day decay. Position sizing on GSBC should anchor to the underlying notional of $67.48 per share and to the trader's directional view on GSBC stock.
GSBC butterfly setup
The GSBC 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 GSBC near $67.48, the first option leg uses a $64.11 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GSBC 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 GSBC shares for the stock leg in covered calls and collars).

GSBC thesis for this butterfly
The market-implied 1-standard-deviation range for GSBC extends from approximately $60.52 on the downside to $74.44 on the upside. A GSBC long call butterfly is a pinning play: it pays maximum at the middle strike if GSBC settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current GSBC IV rank near 11.01% 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 GSBC at 36.00%. As a Financial Services name, GSBC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GSBC-specific events.
GSBC 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. GSBC positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GSBC alongside the broader basket even when GSBC-specific fundamentals are unchanged. Always rebuild the position from current GSBC chain quotes before placing a trade.
