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 SPTM snapshot
As of May 15, 2026, spot at $89.57, ATM IV 15.20%, IV rank 32.88%, expected move 4.36%. The straddle on SPTM 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 SPTM specifically: SPTM IV at 15.20% 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 4.36% (roughly $3.90 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 SPTM expiries trade a higher absolute premium for lower per-day decay. Position sizing on SPTM should anchor to the underlying notional of $89.57 per share and to the trader's directional view on SPTM etf.
SPTM straddle setup
The SPTM 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 SPTM near $89.57, the first option leg uses a $90.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SPTM 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 SPTM shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $90.00 | $1.63 |
| Buy 1 | Put | $90.00 | $1.70 |

When traders use straddle on SPTM
Straddles on SPTM are pure-volatility plays that profit from large moves in either direction; traders typically buy SPTM straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
SPTM thesis for this straddle
The market-implied 1-standard-deviation range for SPTM extends from approximately $85.67 on the downside to $93.47 on the upside. A SPTM 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 SPTM IV rank near 32.88% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on SPTM should anchor more to the directional view and the expected-move geometry. As a Financial Services name, SPTM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SPTM-specific events.
SPTM 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. SPTM positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SPTM alongside the broader basket even when SPTM-specific fundamentals are unchanged. Always rebuild the position from current SPTM chain quotes before placing a trade.
