Current PRLB snapshot
As of May 14, 2026, spot at $71.94, ATM IV 37.10%, IV rank 26.94%, expected move 10.64%. The bull call spread on PRLB 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 35-day expiry.
Why this bull call spread structure on PRLB specifically: PRLB IV at 37.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRLB bull call spread, with a market-implied 1-standard-deviation move of approximately 10.64% (roughly $7.65 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PRLB expiries trade a higher absolute premium for lower per-day decay.

PRLB bull call spread setup
The PRLB 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 PRLB near $71.94, the first option leg uses a $71.94 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PRLB chain at a 35-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 PRLB shares for the stock leg in covered calls and collars).

A PRLB bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on PRLB, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current PRLB IV rank near 26.94% 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 PRLB at 37.10%. As a Industrials name, PRLB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PRLB-specific events.
PRLB 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. PRLB positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PRLB alongside the broader basket even when PRLB-specific fundamentals are unchanged. Long-premium structures like a bull call spread on PRLB 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.
