MOS Collar Strategy
MOS (The Mosaic Company), in the Basic Materials sector, (Agricultural Inputs industry), listed on NYSE.
The Mosaic Company, through its subsidiaries, produces and markets concentrated phosphate and potash crop nutrients in North America and internationally. The company operates through three segments: Phosphates, Potash, and Mosaic Fertilizantes. It owns and operates mines, which produce concentrated phosphate crop nutrients, such as diammonium phosphate, monoammonium phosphate, and ammoniated phosphate products; and phosphate-based animal feed ingredients primarily under the Biofos and Nexfos brand names, as well as produces a double sulfate of potash magnesia product under K-Mag brand name. The company also produces and sells potash for use in the manufacturing of mixed crop nutrients and animal feed ingredients, and for industrial use; and for use in the de-icing and as a water softener regenerant. In addition, it provides nitrogen-based crop nutrients, animal feed ingredients, and other ancillary services; and purchases and sells phosphates, potash, and nitrogen products. The company sells its products to wholesale distributors, retail chains, farmers, cooperatives, independent retailers, and national accounts.
MOS (The Mosaic Company) trades in the Basic Materials sector, specifically Agricultural Inputs, with a market capitalization of approximately $7.24B, a trailing P/E of 9.95, a beta of 0.80 versus the broader market, a 52-week range of 21.17-38.23, average daily share volume of 9.9M, a public-listing history dating back to 1988, approximately 14K full-time employees. These structural characteristics shape how MOS stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.80 places MOS roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 9.95 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. MOS pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a collar on MOS?
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 MOS snapshot
As of May 15, 2026, spot at $21.79, ATM IV 45.36%, IV rank 57.64%, expected move 13.00%. The collar on MOS 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 28-day expiry.
Why this collar structure on MOS specifically: IV regime affects collar pricing on both sides; mid-range MOS IV at 45.36% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 13.00% (roughly $2.83 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MOS expiries trade a higher absolute premium for lower per-day decay. Position sizing on MOS should anchor to the underlying notional of $21.79 per share and to the trader's directional view on MOS stock.
MOS collar setup
The MOS 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 MOS near $21.79, the first option leg uses a $23.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MOS chain at a 28-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 MOS shares for the stock leg in covered calls and collars).

| Buy 100 shares | Stock | $21.79 | long |
| Sell 1 | Call | $23.00 | $0.63 |
| Buy 1 | Put | $21.00 | $0.78 |

Collars on MOS hedge an existing long MOS 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.
MOS thesis for this collar
The market-implied 1-standard-deviation range for MOS extends from approximately $18.96 on the downside to $24.62 on the upside. A MOS collar hedges an existing long MOS 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 MOS IV rank near 57.64% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on MOS should anchor more to the directional view and the expected-move geometry. As a Basic Materials name, MOS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MOS-specific events.
MOS 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. MOS positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MOS alongside the broader basket even when MOS-specific fundamentals are unchanged. Always rebuild the position from current MOS chain quotes before placing a trade.
