What is a strangle on TAC?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
Current TAC snapshot
As of May 15, 2026, spot at $12.82, ATM IV 46.00%, IV rank 25.38%, expected move 13.19%. The strangle on TAC 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 strangle structure on TAC specifically: TAC IV at 46.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a TAC strangle, with a market-implied 1-standard-deviation move of approximately 13.19% (roughly $1.69 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 TAC expiries trade a higher absolute premium for lower per-day decay. Position sizing on TAC should anchor to the underlying notional of $12.82 per share and to the trader's directional view on TAC stock.
TAC strangle setup
The TAC strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With TAC near $12.82, the first option leg uses a $13.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TAC 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 TAC shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $13.00 | $0.63 |
| Buy 1 | Put | $12.00 | $0.38 |

When traders use strangle on TAC
Strangles on TAC are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the TAC chain.
TAC thesis for this strangle
The market-implied 1-standard-deviation range for TAC extends from approximately $11.13 on the downside to $14.51 on the upside. A TAC long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current TAC IV rank near 25.38% 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 TAC at 46.00%. As a Utilities name, TAC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TAC-specific events.
TAC strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. TAC positions also carry Utilities sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TAC alongside the broader basket even when TAC-specific fundamentals are unchanged. Always rebuild the position from current TAC chain quotes before placing a trade.

Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current TAC market-implied 1-standard-deviation expected move is approximately 13.19%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
