What is a collar on FSTR?
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 FSTR snapshot
As of May 15, 2026, spot at $38.91, ATM IV 55.70%, IV rank 20.81%, expected move 15.97%. The collar on FSTR 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 FSTR specifically: IV regime affects collar pricing on both sides; compressed FSTR IV at 55.70% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 15.97% (roughly $6.21 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 FSTR expiries trade a higher absolute premium for lower per-day decay. Position sizing on FSTR should anchor to the underlying notional of $38.91 per share and to the trader's directional view on FSTR stock.
FSTR collar setup
The FSTR 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 FSTR near $38.91, the first option leg uses a $40.86 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FSTR 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 FSTR shares for the stock leg in covered calls and collars).

| Buy 100 shares | Stock | $38.91 | long |
| Sell 1 | Call | $40.86 | N/A |
| Buy 1 | Put | $36.96 | N/A |

FSTR thesis for this collar
The market-implied 1-standard-deviation range for FSTR extends from approximately $32.70 on the downside to $45.12 on the upside. A FSTR collar hedges an existing long FSTR 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 FSTR IV rank near 20.81% 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 FSTR at 55.70%. As a Industrials name, FSTR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FSTR-specific events.
FSTR 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. FSTR positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FSTR alongside the broader basket even when FSTR-specific fundamentals are unchanged. Always rebuild the position from current FSTR chain quotes before placing a trade.
