BY (Byline Bancorp, Inc.) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $1.47B, a trailing P/E of 10.40, a beta of 0.75 versus the broader market, a 52-week range of 24.75-34.33, average daily share volume of 211K, a public-listing history dating back to 2017, approximately 1K full-time employees. These structural characteristics shape how BY stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.75 places BY roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 10.40 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. BY pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a long put on BY?
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 BY snapshot
As of May 15, 2026, spot at $32.08, ATM IV 84.20%, IV rank 33.59%, expected move 24.14%. The long put on BY 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 BY specifically: BY IV at 84.20% 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 24.14% (roughly $7.74 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 BY expiries trade a higher absolute premium for lower per-day decay. Position sizing on BY should anchor to the underlying notional of $32.08 per share and to the trader's directional view on BY stock.
BY long put setup
The BY 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 BY near $32.08, the first option leg uses a $32.08 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BY 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 BY shares for the stock leg in covered calls and collars).

BY thesis for this long put
The market-implied 1-standard-deviation range for BY extends from approximately $24.34 on the downside to $39.82 on the upside. A BY long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long BY position with one put per 100 shares held. Current BY IV rank near 33.59% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on BY should anchor more to the directional view and the expected-move geometry. As a Financial Services name, BY options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BY-specific events.
BY 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. BY positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BY alongside the broader basket even when BY-specific fundamentals are unchanged. Long-premium structures like a long put on BY 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 BY chain quotes before placing a trade.
