How are CWB straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the CWB straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 22.80%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$439.28 per contract. Live intraday quotes will differ as the chain moves through the trading session.

Current CWB snapshot

As of June 29, 2026, spot at $107.91, ATM IV 22.80%, IV rank 34.48%, expected move 6.54%. The straddle on CWB 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 18-day expiry.

Why this straddle structure on CWB specifically: CWB IV at 22.80% 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 6.54% (roughly $7.05 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CWB expiries trade a higher absolute premium for lower per-day decay. Position sizing on CWB should anchor to the underlying notional of $107.91 per share and to the trader's directional view on CWB etf.

CWB straddle setup

The CWB straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CWB near $107.91, the first option leg uses a $108.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CWB chain at a 18-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 CWB shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$108.00	$1.90
Buy 1	Put	$108.00	$2.95

When traders use straddle on CWB

Straddles on CWB are pure-volatility plays that profit from large moves in either direction; traders typically buy CWB straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

CWB thesis for this straddle

The market-implied 1-standard-deviation range for CWB extends from approximately $100.86 on the downside to $114.96 on the upside. A CWB long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current CWB IV rank near 34.48% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on CWB should anchor more to the directional view and the expected-move geometry. As a Financial Services name, CWB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CWB-specific events.

CWB straddle positions are structurally neutral / high-volatility (long premium); 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. CWB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CWB alongside the broader basket even when CWB-specific fundamentals are unchanged. Always rebuild the position from current CWB chain quotes before placing a trade.
