What is a straddle on VNRX?
A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.
Current VNRX snapshot
As of May 15, 2026, spot at $2.06, ATM IV 28.50%, IV rank 2.28%, expected move 8.17%. The straddle on VNRX 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 straddle structure on VNRX specifically: VNRX IV at 28.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a VNRX straddle, with a market-implied 1-standard-deviation move of approximately 8.17% (roughly $0.17 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 VNRX expiries trade a higher absolute premium for lower per-day decay. Position sizing on VNRX should anchor to the underlying notional of $2.06 per share and to the trader's directional view on VNRX stock.
VNRX straddle setup
The VNRX straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With VNRX near $2.06, the first option leg uses a $2.06 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed VNRX 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 VNRX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

| Buy 1 | Put | $2.06 | N/A |

When traders use straddle on VNRX

VNRX thesis for this straddle
The market-implied 1-standard-deviation range for VNRX extends from approximately $1.89 on the downside to $2.23 on the upside. A VNRX long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current VNRX IV rank near 2.28% 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 VNRX at 28.50%. As a Healthcare name, VNRX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to VNRX-specific events.
VNRX straddle positions are structurally neutral / high-volatility (long premium); 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. VNRX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move VNRX alongside the broader basket even when VNRX-specific fundamentals are unchanged. Always rebuild the position from current VNRX chain quotes before placing a trade.
