The breakeven for the CME bear put spread priced on this page is roughly $216.15 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.

Current CME snapshot

As of June 30, 2026, spot at $221.01, ATM IV 34.37%, IV rank 92.76%, expected move 9.85%. The bear put spread on CME 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 31-day expiry.

Why this bear put spread structure on CME specifically: CME IV at 34.37% is rich versus its 1-year range, which makes a premium-buying CME bear put spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 9.85% (roughly $21.78 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CME expiries trade a higher absolute premium for lower per-day decay. Position sizing on CME should anchor to the underlying notional of $221.01 per share and to the trader's directional view on CME stock.

CME bear put spread setup

The CME bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CME near $221.01, the first option leg uses a $220.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CME chain at a 31-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 CME shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Put	$220.00	$8.10
Sell 1	Put	$210.00	$4.25

Bear put spreads on CME reduce the cost of a bearish CME stock position by selling a lower-strike put; suited to moderate-decline theses where price reaches but does not vastly exceed the short strike.

CME thesis for this bear put spread

The market-implied 1-standard-deviation range for CME extends from approximately $199.23 on the downside to $242.79 on the upside. A CME bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on CME, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current CME IV rank near 92.76% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on CME at 34.37%. As a Financial Services name, CME options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CME-specific events.

CME bear put spread positions are structurally moderately bearish; 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. CME positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CME alongside the broader basket even when CME-specific fundamentals are unchanged. Long-premium structures like a bear put spread on CME are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current CME chain quotes before placing a trade.
