Current TAC snapshot

As of June 29, 2026, spot at $13.65, ATM IV 39.00%, IV rank 4.30%, expected move 11.18%. 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 53-day expiry.

Why this collar structure on TAC specifically: IV regime affects collar pricing on both sides; compressed TAC IV at 39.00% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 11.18% (roughly $1.53 on the underlying). The 53-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 $13.65 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 $13.65, the first option leg uses a $14.00 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 53-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 100 shares	Stock	$13.65	long
Sell 1	Call	$14.00	$0.85
Buy 1	Put	$13.00	$0.75

When traders use collar on TAC

Collars on TAC hedge an existing long TAC stock position; the long put sets a floor while the short call finances it, often run as a near-zero-cost hedge during expected volatility windows.

TAC thesis for this collar

The market-implied 1-standard-deviation range for TAC extends from approximately $12.12 on the downside to $15.18 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 4.30% 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 39.00%. 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.
