Current QTRX snapshot

As of May 15, 2026, spot at $2.79, ATM IV 104.20%, IV rank 31.38%, expected move 29.87%. The long call on QTRX 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 QTRX specifically: QTRX IV at 104.20% 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 29.87% (roughly $0.83 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 QTRX expiries trade a higher absolute premium for lower per-day decay. Position sizing on QTRX should anchor to the underlying notional of $2.79 per share and to the trader's directional view on QTRX stock.

QTRX long call setup

The QTRX 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 QTRX near $2.79, the first option leg uses a $2.79 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed QTRX 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 QTRX shares for the stock leg in covered calls and collars).

QTRX thesis for this long call

The market-implied 1-standard-deviation range for QTRX extends from approximately $1.96 on the downside to $3.62 on the upside. A QTRX 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 QTRX IV rank near 31.38% is mid-range against its 1-year distribution, so the IV signal is neutral; the long call thesis on QTRX should anchor more to the directional view and the expected-move geometry. As a Healthcare name, QTRX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to QTRX-specific events.

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