ACNB (ACNB Corporation) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $536.4M, a trailing P/E of 10.65, a beta of 0.87 versus the broader market, a 52-week range of 40.15-53.93, average daily share volume of 60K, a public-listing history dating back to 1994, approximately 391 full-time employees. These structural characteristics shape how ACNB stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.87 places ACNB roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 10.65 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. ACNB pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a long put on ACNB?

A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.

Current ACNB snapshot

As of May 15, 2026, spot at $52.28, ATM IV 45.20%, IV rank 22.53%, expected move 12.96%. The long put on ACNB 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 long put structure on ACNB specifically: ACNB IV at 45.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a ACNB long put, with a market-implied 1-standard-deviation move of approximately 12.96% (roughly $6.77 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 ACNB expiries trade a higher absolute premium for lower per-day decay. Position sizing on ACNB should anchor to the underlying notional of $52.28 per share and to the trader's directional view on ACNB stock.

ACNB long put setup

The ACNB long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With ACNB near $52.28, the first option leg uses a $52.28 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ACNB 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 ACNB shares for the stock leg in covered calls and collars).

ACNB thesis for this long put

The market-implied 1-standard-deviation range for ACNB extends from approximately $45.51 on the downside to $59.05 on the upside. A ACNB long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long ACNB position with one put per 100 shares held. Current ACNB IV rank near 22.53% 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 ACNB at 45.20%. As a Financial Services name, ACNB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ACNB-specific events.

ACNB long put positions are structurally bearish; 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. ACNB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ACNB alongside the broader basket even when ACNB-specific fundamentals are unchanged. Long-premium structures like a long put on ACNB are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current ACNB chain quotes before placing a trade.
