PLX (Protalix BioTherapeutics, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $155.5M, a trailing P/E of 10.05, a beta of -0.01 versus the broader market, a 52-week range of 1.32-3.19, average daily share volume of 970K, a public-listing history dating back to 1998, approximately 213 full-time employees. These structural characteristics shape how PLX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of -0.01 indicates PLX has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 10.05 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price.

What is a long call on PLX?

A long call buys upside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes above the strike plus premium at expiration.

Current PLX snapshot

As of May 15, 2026, spot at $2.02, ATM IV 476.60%, IV rank 95.33%, expected move 136.64%. The long call on PLX 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 34-day expiry.

Why this long call structure on PLX specifically: PLX IV at 476.60% is rich versus its 1-year range, which makes a premium-buying PLX long call relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 136.64% (roughly $2.76 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PLX expiries trade a higher absolute premium for lower per-day decay. Position sizing on PLX should anchor to the underlying notional of $2.02 per share and to the trader's directional view on PLX stock.

PLX long call setup

The PLX long call below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With PLX near $2.02, the first option leg uses a $2.02 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PLX chain at a 34-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 PLX shares for the stock leg in covered calls and collars).

When traders use long call on PLX

Long calls on PLX express a bullish thesis with defined risk; traders use them ahead of PLX catalysts (earnings, product launches, macro events) when the expected upside justifies the premium and theta decay.

PLX thesis for this long call

The market-implied 1-standard-deviation range for PLX extends from approximately $-0.74 on the downside to $4.78 on the upside. A PLX long call expresses a directional view that the underlying closes above the strike plus premium at expiration, ideally with implied volatility holding or expanding to preserve extrinsic value through the hold period. Current PLX IV rank near 95.33% 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 PLX at 476.60%. As a Healthcare name, PLX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PLX-specific events.

PLX long call positions are structurally 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. PLX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PLX alongside the broader basket even when PLX-specific fundamentals are unchanged. Long-premium structures like a long call on PLX 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 PLX chain quotes before placing a trade.
