CABA (Cabaletta Bio, Inc.), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.
Cabaletta Bio, Inc. is a biotechnology firm in the clinical development stage, specializing in the invention and advancement of sophisticated engineered T cell therapies. Its core mission is to treat autoimmune diseases where B cells are implicated in producing harmful autoantibodies. The company's unique chimeric autoantibody receptor (CAAR) T cell platform is engineered to precisely target and eradicate these specific disease-causing B cells. Leading its pipeline is DSG3-CAART, which is currently in Phase I clinical trials. This candidate is being assessed for efficacy in two distinct conditions: mucosal pemphigus vulgaris, an autoimmune blistering skin disorder, and Hemophilia A in patients exhibiting Factor VIII alloantibodies. Cabaletta's broader product candidate portfolio also includes MuSK-CAART, a preclinical asset aimed at a particular subset of myasthenia gravis patients; FVIII-CAART, in the discovery phase for another subgroup of Hemophilia A sufferers; and DSG3/1-CAART, also a discovery-stage program, designed for mucocutaneous pemphigus vulgaris.

What is a strangle on CABA?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
Current CABA snapshot
As of June 30, 2026, spot at $3.10, ATM IV 48.40%, IV rank 4.92%, expected move 13.88%. The strangle on CABA 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 strangle structure on CABA specifically: CABA IV at 48.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a CABA strangle, with a market-implied 1-standard-deviation move of approximately 13.88% (roughly $0.43 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 CABA expiries trade a higher absolute premium for lower per-day decay. Position sizing on CABA should anchor to the underlying notional of $3.10 per share and to the trader's directional view on CABA stock.
CABA strangle setup
The CABA strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CABA near $3.10, the first option leg uses a $3.26 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CABA 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 CABA shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $3.26 | N/A |
| Buy 1 | Put | $2.95 | N/A |

CABA thesis for this strangle
The market-implied 1-standard-deviation range for CABA extends from approximately $2.67 on the downside to $3.53 on the upside. A CABA long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current CABA IV rank near 4.92% 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 CABA at 48.40%. As a Healthcare name, CABA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CABA-specific events.
CABA strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. CABA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CABA alongside the broader basket even when CABA-specific fundamentals are unchanged. Always rebuild the position from current CABA chain quotes before placing a trade.
