EQ (Equillium, Inc.), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.
Equillium, Inc. is a clinical-stage biopharmaceutical company focused on developing and bringing to market products designed to address severe autoimmune and inflammatory (immuno-inflammatory) disorders where current treatment options are insufficient. The company's primary drug candidate is itolizumab (EQ001), a monoclonal antibody in clinical development that targets the novel CD6 immune checkpoint receptor. Itolizumab is currently in Phase III trials for acute graft-versus-host disease, has completed Phase Ib studies for asthma, and is also undergoing Phase Ib trials for lupus nephritis. In addition to itolizumab, Equillium is advancing EQ101 for the treatment of cutaneous T cell lymphoma and alopecia areata, and EQ102, which targets various gastrointestinal conditions. Headquartered in La Jolla, California, the company was incorporated in 2017 and previously operated as Attenuate Biopharmaceuticals, Inc. before changing its name to Equillium, Inc. in May 2017.
EQ (Equillium, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $108.3M, a beta of 1.78 versus the broader market, a 52-week range of 0.29-3.45, average daily share volume of 605K, a public-listing history dating back to 2018, approximately 35 full-time employees. These structural characteristics shape how EQ stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a long put on EQ?
A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.
Current EQ snapshot
As of June 30, 2026, spot at $3.15, ATM IV 138.90%, IV rank 24.41%, expected move 39.82%. The long put on EQ 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 17-day expiry.
Why this long put structure on EQ specifically: EQ IV at 138.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a EQ long put, with a market-implied 1-standard-deviation move of approximately 39.82% (roughly $1.25 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated EQ expiries trade a higher absolute premium for lower per-day decay. Position sizing on EQ should anchor to the underlying notional of $3.15 per share and to the trader's directional view on EQ stock.
EQ long put setup
The EQ long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With EQ near $3.15, the first option leg uses a $3.15 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EQ chain at a 17-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 EQ shares for the stock leg in covered calls and collars).

EQ thesis for this long put
The market-implied 1-standard-deviation range for EQ extends from approximately $1.90 on the downside to $4.40 on the upside. A EQ long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long EQ position with one put per 100 shares held. Current EQ IV rank near 24.41% 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 EQ at 138.90%. As a Healthcare name, EQ options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EQ-specific events.
EQ long put positions are structurally 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. EQ positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move EQ alongside the broader basket even when EQ-specific fundamentals are unchanged. Long-premium structures like a long put on EQ 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 EQ chain quotes before placing a trade.
