What is a straddle on BMO?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

Current BMO snapshot

As of June 29, 2026, spot at $176.13, ATM IV 17.40%, IV rank 39.41%, expected move 4.99%. The straddle on BMO 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 BMO specifically: BMO IV at 17.40% 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 4.99% (roughly $8.79 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 BMO expiries trade a higher absolute premium for lower per-day decay. Position sizing on BMO should anchor to the underlying notional of $176.13 per share and to the trader's directional view on BMO stock.

BMO straddle setup

The BMO 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 BMO near $176.13, the first option leg uses a $175.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BMO 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 BMO shares for the stock leg in covered calls and collars).

When traders use straddle on BMO

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

BMO thesis for this straddle

The market-implied 1-standard-deviation range for BMO extends from approximately $167.34 on the downside to $184.92 on the upside. A BMO 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 BMO IV rank near 39.41% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on BMO should anchor more to the directional view and the expected-move geometry. As a Financial Services name, BMO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BMO-specific events.

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