DUK (Duke Energy Corporation), in the Utilities sector, (Regulated Electric industry), listed on NYSE.
Duke Energy Corporation, together with its subsidiaries, operates as an energy company in the United States. It operates through three segments: Electric Utilities and Infrastructure, Gas Utilities and Infrastructure, and Commercial Renewables. The Electric Utilities and Infrastructure segment generates, transmits, distributes, and sells electricity in the Carolinas, Florida, and the Midwest; and uses coal, hydroelectric, natural gas, oil, renewable generation, and nuclear fuel to generate electricity. It also engages in the wholesale of electricity to municipalities, electric cooperative utilities, and load-serving entities. This segment serves approximately 8.2 million customers in 6 states in the Southeast and Midwest regions of the United States covering a service territory of approximately 91,000 square miles; and owns approximately 50,259 megawatts (MW) of generation capacity. The Gas Utilities and Infrastructure segment distributes natural gas to residential, commercial, industrial, and power generation natural gas customers; and owns, operates, and invests in pipeline transmission and natural gas storage facilities.
DUK (Duke Energy Corporation) trades in the Utilities sector, specifically Regulated Electric, with a market capitalization of approximately $96.59B, a trailing P/E of 18.76, a beta of 0.40 versus the broader market, a 52-week range of 113.37-134.49, average daily share volume of 4.0M, a public-listing history dating back to 1980, approximately 26K full-time employees. These structural characteristics shape how DUK stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.40 indicates DUK has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. DUK pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a straddle on DUK?
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 DUK snapshot
As of May 15, 2026, spot at $121.15, ATM IV 19.00%, IV rank 52.71%, expected move 5.45%. The straddle on DUK 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 DUK specifically: DUK IV at 19.00% 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 5.45% (roughly $6.60 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 DUK expiries trade a higher absolute premium for lower per-day decay. Position sizing on DUK should anchor to the underlying notional of $121.15 per share and to the trader's directional view on DUK stock.
DUK straddle setup
The DUK 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 DUK near $121.15, the first option leg uses a $120.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DUK 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 DUK shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $120.00 | $3.65 |
| Buy 1 | Put | $120.00 | $2.10 |

When traders use straddle on DUK
Straddles on DUK are pure-volatility plays that profit from large moves in either direction; traders typically buy DUK straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
DUK thesis for this straddle
The market-implied 1-standard-deviation range for DUK extends from approximately $114.55 on the downside to $127.75 on the upside. A DUK 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 DUK IV rank near 52.71% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on DUK should anchor more to the directional view and the expected-move geometry. As a Utilities name, DUK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DUK-specific events.
DUK 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. DUK positions also carry Utilities sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DUK alongside the broader basket even when DUK-specific fundamentals are unchanged. Always rebuild the position from current DUK chain quotes before placing a trade.
