How are PSA 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 PSA straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 25.00%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$1,721.16 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a PSA straddle?

The breakeven for the PSA straddle priced on this page is roughly $272.40 and $307.60 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 PSA market-implied 1-standard-deviation expected move is approximately 7.17%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current PSA implied volatility affect this straddle?

PSA Straddle Strategy

PSA (Public Storage), in the Real Estate sector, (REIT - Industrial industry), listed on NYSE.

Public Storage, a member of the S&P 500 and FT Global 500, is a REIT that primarily acquires, develops, owns and operates self-storage facilities. At September 30, 2020, we had: (i) interests in 2,504 self-storage facilities located in 38 states with approximately 171 million net rentable square feet in the United States, (ii) an approximate 35% common equity interest in Shurgard Self Storage SA (Euronext Brussels:SHUR) which owned 239 self-storage facilities located in seven Western European nations with approximately 13 million net rentable square feet operated under the Shurgard brand and (iii) an approximate 42% common equity interest in PS Business Parks, Inc. (NYSE:PSB) which owned and operated approximately 28 million rentable square feet of commercial space at September 30, 2020. Our headquarters are located in Glendale, California.

PSA (Public Storage) trades in the Real Estate sector, specifically REIT - Industrial, with a market capitalization of approximately $53.31B, a trailing P/E of 28.01, a beta of 0.98 versus the broader market, a 52-week range of 256.54-313.51, average daily share volume of 1.2M, a public-listing history dating back to 1980, approximately 6K full-time employees. These structural characteristics shape how PSA stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.98 places PSA roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. PSA pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a straddle on PSA?

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 PSA snapshot

As of May 15, 2026, spot at $291.85, ATM IV 25.00%, IV rank 53.28%, expected move 7.17%. The straddle on PSA 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 straddle structure on PSA specifically: PSA IV at 25.00% 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 7.17% (roughly $20.92 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 PSA expiries trade a higher absolute premium for lower per-day decay. Position sizing on PSA should anchor to the underlying notional of $291.85 per share and to the trader's directional view on PSA stock.

PSA straddle setup

The PSA 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 PSA near $291.85, the first option leg uses a $290.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PSA 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 PSA shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$290.00	$9.90
Buy 1	Put	$290.00	$7.70

When traders use straddle on PSA

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

PSA thesis for this straddle

The market-implied 1-standard-deviation range for PSA extends from approximately $270.93 on the downside to $312.77 on the upside. A PSA 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 PSA IV rank near 53.28% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on PSA should anchor more to the directional view and the expected-move geometry. As a Real Estate name, PSA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PSA-specific events.

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