What is a straddle on REPX?
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 REPX snapshot
As of May 15, 2026, spot at $36.83, ATM IV 46.60%, IV rank 14.85%, expected move 13.36%. The straddle on REPX 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 REPX specifically: REPX IV at 46.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a REPX straddle, with a market-implied 1-standard-deviation move of approximately 13.36% (roughly $4.92 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 REPX expiries trade a higher absolute premium for lower per-day decay. Position sizing on REPX should anchor to the underlying notional of $36.83 per share and to the trader's directional view on REPX stock.
REPX straddle setup
The REPX 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 REPX near $36.83, the first option leg uses a $36.83 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed REPX 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 REPX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

When traders use straddle on REPX

REPX thesis for this straddle
The market-implied 1-standard-deviation range for REPX extends from approximately $31.91 on the downside to $41.75 on the upside. A REPX 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 REPX IV rank near 14.85% 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 REPX at 46.60%. As a Energy name, REPX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to REPX-specific events.
REPX 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. REPX positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move REPX alongside the broader basket even when REPX-specific fundamentals are unchanged. Always rebuild the position from current REPX chain quotes before placing a trade.
