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 collar 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 collar structure on TAC specifically: IV regime affects collar pricing on both sides; compressed TAC IV at 46.00% typically pushes the short call premium to roughly offset the long put cost, 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 collar setup
The TAC collar 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).

TAC thesis for this collar
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 collar hedges an existing long TAC position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. 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 collar positions are structurally neutral (protective); 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.
