How are EXR 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 EXR straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 22.50%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$558.78 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a EXR straddle?

The breakeven for the EXR straddle priced on this page is roughly $139.30 and $150.70 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current EXR market-implied 1-standard-deviation expected move is approximately 6.45%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current EXR implied volatility affect this straddle?

Current EXR snapshot

As of June 30, 2026, spot at $145.84, ATM IV 22.50%, IV rank 24.93%, expected move 6.45%. The straddle on EXR 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 17-day expiry.

Why this straddle structure on EXR specifically: EXR IV at 22.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a EXR straddle, with a market-implied 1-standard-deviation move of approximately 6.45% (roughly $9.41 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated EXR expiries trade a higher absolute premium for lower per-day decay. Position sizing on EXR should anchor to the underlying notional of $145.84 per share and to the trader's directional view on EXR stock.

EXR straddle setup

The EXR 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 EXR near $145.84, the first option leg uses a $145.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EXR chain at a 17-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 EXR shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$145.00	$3.60
Buy 1	Put	$145.00	$2.10

When traders use straddle on EXR

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

EXR thesis for this straddle

The market-implied 1-standard-deviation range for EXR extends from approximately $136.43 on the downside to $155.25 on the upside. A EXR 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 EXR IV rank near 24.93% 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 EXR at 22.50%. As a Real Estate name, EXR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EXR-specific events.

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