How are DCI 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 DCI straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 33.30%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$891.89 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a DCI straddle?

The breakeven for the DCI straddle priced on this page is roughly $70.68 and $89.33 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 DCI market-implied 1-standard-deviation expected move is approximately 9.55%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current DCI implied volatility affect this straddle?

DCI ATM IV is at 33.30% with IV rank near 5.78%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

Current DCI snapshot

As of May 15, 2026, spot at $81.64, ATM IV 33.30%, IV rank 5.78%, expected move 9.55%. The straddle on DCI 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 98-day expiry.

Why this straddle structure on DCI specifically: DCI IV at 33.30% is on the cheap side of its 1-year range, which favors premium-buying structures like a DCI straddle, with a market-implied 1-standard-deviation move of approximately 9.55% (roughly $7.79 on the underlying). The 98-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated DCI expiries trade a higher absolute premium for lower per-day decay. Position sizing on DCI should anchor to the underlying notional of $81.64 per share and to the trader's directional view on DCI stock.

DCI straddle setup

The DCI 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 DCI near $81.64, the first option leg uses a $80.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DCI chain at a 98-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 DCI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$80.00	$6.00
Buy 1	Put	$80.00	$3.33

When traders use straddle on DCI

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

DCI thesis for this straddle

The market-implied 1-standard-deviation range for DCI extends from approximately $73.85 on the downside to $89.43 on the upside. A DCI 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 DCI IV rank near 5.78% 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 DCI at 33.30%. As a Industrials name, DCI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DCI-specific events.

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