How are RYTM 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 RYTM straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 51.30%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$933.35 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a RYTM straddle?

The breakeven for the RYTM straddle priced on this page is roughly $100.15 and $119.85 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 RYTM market-implied 1-standard-deviation expected move is approximately 14.71%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current RYTM implied volatility affect this straddle?

RYTM ATM IV is at 51.30% with IV rank near 13.22%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

RYTM Straddle Strategy

RYTM (Rhythm Pharmaceuticals, Inc.), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.

Rhythm Pharmaceuticals, Inc. is a biopharmaceutical company with commercial products, dedicated to the discovery, development, and market launch of therapies addressing rare genetic conditions that cause obesity. Its leading pharmaceutical, IMCIVREE, functions as a powerful agonist of the melanocortin-4 receptor (MC4R). This medication is indicated for treating obesity stemming from deficiencies in pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or the leptin receptor (LEPR), alongside its use in patients with Bardet-Biedl and Alström syndromes. Furthermore, the company is progressing setmelanotide (the active compound in IMCIVREE) through Phase II clinical trials. These studies are evaluating its potential for a broader spectrum of applications, including obesity caused by heterozygous POMC or LEPR deficiencies, steroid receptor coactivator 1 (SRC1) deficiency, SH2B1 deficiency, MC4 receptor deficiency, and obesity associated with Smith-Magenis syndrome, POMC epigenetic disorders, and other MC4R-related conditions. Rhythm Pharmaceuticals holds a collaborative research agreement with the Clinical Registry Investigating Bardet-Biedl Syndrome.

RYTM (Rhythm Pharmaceuticals, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $7.53B, a beta of 1.92 versus the broader market, a 52-week range of 62.29-122.2, average daily share volume of 815K, a public-listing history dating back to 2017, approximately 283 full-time employees. These structural characteristics shape how RYTM stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.92 indicates RYTM has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position.

What is a straddle on RYTM?

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 RYTM snapshot

As of June 30, 2026, spot at $112.30, ATM IV 51.30%, IV rank 13.22%, expected move 14.71%. The straddle on RYTM 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 straddle structure on RYTM specifically: RYTM IV at 51.30% is on the cheap side of its 1-year range, which favors premium-buying structures like a RYTM straddle, with a market-implied 1-standard-deviation move of approximately 14.71% (roughly $16.52 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 RYTM expiries trade a higher absolute premium for lower per-day decay. Position sizing on RYTM should anchor to the underlying notional of $112.30 per share and to the trader's directional view on RYTM stock.

RYTM straddle setup

The RYTM 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 RYTM near $112.30, the first option leg uses a $110.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RYTM 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 RYTM shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$110.00	$5.90
Buy 1	Put	$110.00	$3.95

When traders use straddle on RYTM

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

RYTM thesis for this straddle

The market-implied 1-standard-deviation range for RYTM extends from approximately $95.78 on the downside to $128.82 on the upside. A RYTM 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 RYTM IV rank near 13.22% 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 RYTM at 51.30%. As a Healthcare name, RYTM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RYTM-specific events.

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