TAC bear put spread setup
The TAC bear put spread 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 bear put spread
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 bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on TAC, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. 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 bear put spread positions are structurally moderately bearish; 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. Long-premium structures like a bear put spread on TAC are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current TAC chain quotes before placing a trade.
