Current CLIR snapshot
As of May 15, 2026, spot at $4.89, ATM IV 53.40%, IV rank 7.00%, expected move 15.31%. The bull call spread on CLIR 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 bull call spread structure on CLIR specifically: CLIR IV at 53.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a CLIR bull call spread, with a market-implied 1-standard-deviation move of approximately 15.31% (roughly $0.75 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 CLIR expiries trade a higher absolute premium for lower per-day decay. Position sizing on CLIR should anchor to the underlying notional of $4.89 per share and to the trader's directional view on CLIR stock.
CLIR bull call spread setup
The CLIR 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 CLIR near $4.89, the first option leg uses a $4.89 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CLIR 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 CLIR shares for the stock leg in covered calls and collars).

CLIR thesis for this bull call spread
The market-implied 1-standard-deviation range for CLIR extends from approximately $4.14 on the downside to $5.64 on the upside. A CLIR bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on CLIR, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current CLIR IV rank near 7.00% 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 CLIR at 53.40%. As a Industrials name, CLIR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CLIR-specific events.
CLIR 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. CLIR positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CLIR alongside the broader basket even when CLIR-specific fundamentals are unchanged. Long-premium structures like a bull call spread on CLIR 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 CLIR chain quotes before placing a trade.
