IBOC (International Bancshares Corporation) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $4.43B, a trailing P/E of 10.67, a beta of 0.71 versus the broader market, a 52-week range of 61.15-75.44, average daily share volume of 397K, a public-listing history dating back to 1995, approximately 2K full-time employees. These structural characteristics shape how IBOC stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.71 places IBOC roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 10.67 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. IBOC pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a collar on IBOC?
A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.
Current IBOC snapshot
As of May 15, 2026, spot at $70.95, ATM IV 45.80%, IV rank 5.70%, expected move 13.13%. The collar on IBOC 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 collar structure on IBOC specifically: IV regime affects collar pricing on both sides; compressed IBOC IV at 45.80% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 13.13% (roughly $9.32 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 IBOC expiries trade a higher absolute premium for lower per-day decay. Position sizing on IBOC should anchor to the underlying notional of $70.95 per share and to the trader's directional view on IBOC stock.
IBOC collar setup
The IBOC collar below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With IBOC near $70.95, the first option leg uses a $74.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IBOC 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 IBOC shares for the stock leg in covered calls and collars).

| Buy 100 shares | Stock | $70.95 | long |
| Sell 1 | Call | $74.50 | N/A |
| Buy 1 | Put | $67.40 | N/A |

IBOC thesis for this collar
The market-implied 1-standard-deviation range for IBOC extends from approximately $61.63 on the downside to $80.27 on the upside. A IBOC collar hedges an existing long IBOC position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. Current IBOC IV rank near 5.70% 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 IBOC at 45.80%. As a Financial Services name, IBOC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IBOC-specific events.
IBOC collar positions are structurally neutral (protective); 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. IBOC positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IBOC alongside the broader basket even when IBOC-specific fundamentals are unchanged. Always rebuild the position from current IBOC chain quotes before placing a trade.
