How are CSL 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 CSL straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 42.10%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$2,652.61 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a CSL straddle?

The breakeven for the CSL straddle priced on this page is roughly $351.70 and $408.30 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 CSL market-implied 1-standard-deviation expected move is approximately 12.07%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current CSL implied volatility affect this straddle?

CSL ATM IV is at 42.10% with IV rank near 56.66%, 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.

Current CSL snapshot

As of June 29, 2026, spot at $376.33, ATM IV 42.10%, IV rank 56.66%, expected move 12.07%. The straddle on CSL 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 18-day expiry.

Why this straddle structure on CSL specifically: CSL IV at 42.10% 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 12.07% (roughly $45.42 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CSL expiries trade a higher absolute premium for lower per-day decay. Position sizing on CSL should anchor to the underlying notional of $376.33 per share and to the trader's directional view on CSL stock.

CSL straddle setup

The CSL 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 CSL near $376.33, the first option leg uses a $380.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CSL chain at a 18-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 CSL shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$380.00	$12.60
Buy 1	Put	$380.00	$15.70

When traders use straddle on CSL

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

CSL thesis for this straddle

The market-implied 1-standard-deviation range for CSL extends from approximately $330.91 on the downside to $421.75 on the upside. A CSL 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 CSL IV rank near 56.66% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on CSL should anchor more to the directional view and the expected-move geometry. As a Industrials name, CSL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CSL-specific events.

CSL 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. CSL positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CSL alongside the broader basket even when CSL-specific fundamentals are unchanged. Always rebuild the position from current CSL chain quotes before placing a trade.
