Current CALX snapshot

As of May 15, 2026, spot at $40.02, ATM IV 43.60%, IV rank 41.59%, expected move 12.50%. The bear put spread on CALX 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 63-day expiry.

Why this bear put spread structure on CALX specifically: CALX IV at 43.60% 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 12.50% (roughly $5.00 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 CALX expiries trade a higher absolute premium for lower per-day decay.

CALX bear put spread setup

The CALX 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 CALX near $40.02, the first option leg uses a $40.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CALX 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 CALX shares for the stock leg in covered calls and collars).

As a Technology name, CALX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CALX-specific events.

CALX 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. CALX positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CALX alongside the broader basket even when CALX-specific fundamentals are unchanged. Long-premium structures like a bear put spread on CALX 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.
