How are CSTM straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the CSTM straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 54.60%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$407.92 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a CSTM straddle?

The breakeven for the CSTM straddle priced on this page is roughly $27.78 and $36.23 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current CSTM market-implied 1-standard-deviation expected move is approximately 15.65%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current CSTM implied volatility affect this straddle?

CSTM ATM IV is at 54.60% with IV rank near 43.04%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.

CSTM Straddle Strategy

CSTM (Constellium SE), in the Basic Materials sector, (Aluminum industry), listed on NYSE.

Constellium SE, together with its subsidiaries, engages in the design, manufacture, and sale of specialty rolled and extruded aluminum products for the packaging, aerospace, and automotive end-markets. The company operates through three segments: Packaging & Automotive Rolled Products, Aerospace & Transportation, and Automotive Structures & Industry. The Packaging & Automotive Rolled Products segment produces rolled aluminum products, including can stock and closure stock for the beverage and food industry, as well as foil stock for the flexible packaging market. It also supplies automotive body sheets and heat exchangers for the automotive market; and specialty reflective sheets. The Aerospace & Transportation segment provides rolled aluminum products, including aerospace plates, sheets, and extrusions; and aerospace wing skins, as well as plates and sheets for use in transportation, industry, and defense applications. The Automotive Structures & Industry segment offers extruded products and technologically advanced structures for the automotive industry, including crash-management systems, body structures, side impact beams, and battery enclosures; and hard and soft alloy extruded profiles for various industry applications in the automotive, engineering, rail, and other transportation end markets.

CSTM (Constellium SE) trades in the Basic Materials sector, specifically Aluminum, with a market capitalization of approximately $4.71B, a trailing P/E of 10.61, a beta of 1.54 versus the broader market, a 52-week range of 11.23-34.61, average daily share volume of 2.5M, a public-listing history dating back to 2013, approximately 12K full-time employees. These structural characteristics shape how CSTM stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.54 indicates CSTM has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. The trailing P/E of 10.61 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price.

What is a straddle on CSTM?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

Current CSTM snapshot

As of May 15, 2026, spot at $32.01, ATM IV 54.60%, IV rank 43.04%, expected move 15.65%. The straddle on CSTM 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 straddle structure on CSTM specifically: CSTM IV at 54.60% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 15.65% (roughly $5.01 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 CSTM expiries trade a higher absolute premium for lower per-day decay. Position sizing on CSTM should anchor to the underlying notional of $32.01 per share and to the trader's directional view on CSTM stock.

CSTM straddle setup

The CSTM straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CSTM near $32.01, the first option leg uses a $32.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CSTM 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 CSTM shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$32.00	$2.13
Buy 1	Put	$32.00	$2.10

When traders use straddle on CSTM

Straddles on CSTM are pure-volatility plays that profit from large moves in either direction; traders typically buy CSTM straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

CSTM thesis for this straddle

The market-implied 1-standard-deviation range for CSTM extends from approximately $27.00 on the downside to $37.02 on the upside. A CSTM long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current CSTM IV rank near 43.04% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on CSTM should anchor more to the directional view and the expected-move geometry. As a Basic Materials name, CSTM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CSTM-specific events.

CSTM straddle positions are structurally neutral / high-volatility (long premium); 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. CSTM positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CSTM alongside the broader basket even when CSTM-specific fundamentals are unchanged. Always rebuild the position from current CSTM chain quotes before placing a trade.
