Current PST snapshot
As of May 15, 2026, spot at $23.36, ATM IV 13.20%, IV rank 4.42%, expected move 3.78%. The straddle on PST 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 PST specifically: PST IV at 13.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a PST straddle, with a market-implied 1-standard-deviation move of approximately 3.78% (roughly $0.88 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 PST expiries trade a higher absolute premium for lower per-day decay. Position sizing on PST should anchor to the underlying notional of $23.36 per share and to the trader's directional view on PST etf.
PST straddle setup
The PST 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 PST near $23.36, the first option leg uses a $23.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PST 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 PST shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $23.00 | $0.60 |
| Buy 1 | Put | $23.00 | $0.20 |

When traders use straddle on PST
Straddles on PST are pure-volatility plays that profit from large moves in either direction; traders typically buy PST straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
PST thesis for this straddle
The market-implied 1-standard-deviation range for PST extends from approximately $22.48 on the downside to $24.24 on the upside. A PST 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 PST IV rank near 4.42% 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 PST at 13.20%. As a Financial Services name, PST options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PST-specific events.
PST 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. PST positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PST alongside the broader basket even when PST-specific fundamentals are unchanged. Always rebuild the position from current PST chain quotes before placing a trade.
