How are SBLK straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the SBLK straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 34.60%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$362.93 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SBLK straddle?

The breakeven for the SBLK straddle priced on this page is roughly $22.28 and $29.73 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current SBLK market-implied 1-standard-deviation expected move is approximately 9.92%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current SBLK implied volatility affect this straddle?

SBLK Straddle Strategy

SBLK (Star Bulk Carriers Corp.), in the Industrials sector, (Marine Shipping industry), listed on NASDAQ.

Star Bulk Carriers Corp., a shipping company, engages in the ocean transportation of dry bulk cargoes worldwide. The company's vessels transport a range of major bulks, including iron ores, coal, and grains, as well as minor bulks, such as bauxite, fertilizers, and steel products. As of December 31, 2021, it had a fleet of 128 vessels with an aggregate capacity of approximately 14.1 million deadweight tons, including 17 Newcastlemax, 24 Capesize, 7 Post Panamax, 41 Kamsarmax, 2 Panamax, 20 Ultramax, and 17 Supramax vessels. The company also provides vessel management services. Star Bulk Carriers Corp. was incorporated in 2006 and is based in Marousi, Greece.

SBLK (Star Bulk Carriers Corp.) trades in the Industrials sector, specifically Marine Shipping, with a market capitalization of approximately $3.04B, a trailing P/E of 35.95, a beta of 0.72 versus the broader market, a 52-week range of 15.78-27.69, average daily share volume of 1.5M, a public-listing history dating back to 2007, approximately 301 full-time employees. These structural characteristics shape how SBLK stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.72 places SBLK roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 35.95 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. SBLK pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a straddle on SBLK?

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 SBLK snapshot

As of May 15, 2026, spot at $26.49, ATM IV 34.60%, IV rank 52.67%, expected move 9.92%. The straddle on SBLK 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 98-day expiry.

Why this straddle structure on SBLK specifically: SBLK IV at 34.60% 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 9.92% (roughly $2.63 on the underlying). The 98-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SBLK expiries trade a higher absolute premium for lower per-day decay. Position sizing on SBLK should anchor to the underlying notional of $26.49 per share and to the trader's directional view on SBLK stock.

SBLK straddle setup

The SBLK 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 SBLK near $26.49, the first option leg uses a $26.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SBLK chain at a 98-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 SBLK shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$26.00	$2.08
Buy 1	Put	$26.00	$1.65

When traders use straddle on SBLK

Straddles on SBLK are pure-volatility plays that profit from large moves in either direction; traders typically buy SBLK straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

SBLK thesis for this straddle

The market-implied 1-standard-deviation range for SBLK extends from approximately $23.86 on the downside to $29.12 on the upside. A SBLK 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 SBLK IV rank near 52.67% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on SBLK should anchor more to the directional view and the expected-move geometry. As a Industrials name, SBLK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SBLK-specific events.

SBLK 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. SBLK positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SBLK alongside the broader basket even when SBLK-specific fundamentals are unchanged. Always rebuild the position from current SBLK chain quotes before placing a trade.
