Current QTRX snapshot
As of June 30, 2026, spot at $4.21, ATM IV 22.50%, IV rank 0.38%, expected move 6.45%. The bear put spread 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 17-day expiry.
Why this bear put spread structure on QTRX specifically: QTRX IV at 22.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a QTRX bear put spread, with a market-implied 1-standard-deviation move of approximately 6.45% (roughly $0.27 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 QTRX expiries trade a higher absolute premium for lower per-day decay. Position sizing on QTRX should anchor to the underlying notional of $4.21 per share and to the trader's directional view on QTRX stock.
QTRX bear put spread setup
The QTRX 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 QTRX near $4.21, the first option leg uses a $4.21 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 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 QTRX shares for the stock leg in covered calls and collars).

QTRX thesis for this bear put spread
The market-implied 1-standard-deviation range for QTRX extends from approximately $3.94 on the downside to $4.48 on the upside. A QTRX bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on QTRX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current QTRX IV rank near 0.38% 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 QTRX at 22.50%. 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 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. 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 bear put spread 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.
