CDLX snapshot
As of August 14, 2026, spot at $4.44, ATM IV 317.00%, IV rank 85.04%, expected move 90.88%. The bull call spread on CDLX below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 63-day expiry.
Why this bull call spread structure on CDLX specifically: CDLX IV at 317.00% is rich versus its 1-year range, which makes a premium-buying CDLX bull call spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 90.88% (roughly $4.04 on the underlying). The 63-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CDLX expiries trade a higher absolute premium for lower per-day decay. Position sizing on CDLX should anchor to the underlying notional of $4.44 per share and to the trader's directional view on CDLX stock.
CDLX bull call spread setup
The CDLX bull call 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 CDLX at $4.44 on that close, the first option leg uses a $4.44 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CDLX chain at a 63-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 CDLX shares for the stock leg in covered calls and collars).

CDLX thesis for this bull call spread
The market-implied 1-standard-deviation range for CDLX extends from approximately $0.40 on the downside to $8.48 on the upside. A CDLX bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on CDLX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current CDLX IV rank near 85.04% 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 CDLX at 317.00%. As a Communication Services name, CDLX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CDLX-specific events.
CDLX bull call spread positions are structurally moderately bullish; 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. CDLX positions also carry Communication Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CDLX alongside the broader basket even when CDLX-specific fundamentals are unchanged. Long-premium structures like a bull call spread on CDLX 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 CDLX chain quotes before placing a trade.
