What is a collar on TGEN?
A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.
Current TGEN snapshot
As of May 15, 2026, spot at $6.48, ATM IV 133.30%, IV rank 27.15%, expected move 38.22%. The collar on TGEN 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 TGEN specifically: IV regime affects collar pricing on both sides; compressed TGEN IV at 133.30% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 38.22% (roughly $2.48 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 TGEN expiries trade a higher absolute premium for lower per-day decay. Position sizing on TGEN should anchor to the underlying notional of $6.48 per share and to the trader's directional view on TGEN stock.
TGEN collar setup
The TGEN 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 TGEN near $6.48, the first option leg uses a $6.80 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TGEN 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 TGEN shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 100 shares | Stock | $6.48 | long |
| Sell 1 | Call | $6.80 | N/A |
| Buy 1 | Put | $6.16 | N/A |

TGEN thesis for this collar
The market-implied 1-standard-deviation range for TGEN extends from approximately $4.00 on the downside to $8.96 on the upside. A TGEN collar hedges an existing long TGEN 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 TGEN IV rank near 27.15% 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 TGEN at 133.30%. As a Industrials name, TGEN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TGEN-specific events.
TGEN 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. TGEN positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TGEN alongside the broader basket even when TGEN-specific fundamentals are unchanged. Always rebuild the position from current TGEN chain quotes before placing a trade.
