Snapshot as of May 15, 2026.
- Spot Price
- $67.39
- Max Pain Strike
- $65.00
- Total OI
- 17.6K
As of May 15, 2026, Halozyme Therapeutics, Inc. (HALO) max pain sits at $65.00, which is below the current spot price of $67.39 (3.5% away). Spot sits 3.5% below max pain - close enough that a routine end-of-cycle gamma roll could pull price toward the level, but far enough that catalyst-driven flow would dominate. HALO sits in the lower-price band (spot $67.39), where $0.50-$2.50 strike spacing makes pin-to-strike effects easy to spot but per-contract dollar gamma is smaller. Total open interest across the listed chain is comparatively thin (17.6K contracts), so single-strike pinning is less reliable than it is for high-OI names. HALO is currently in positive dealer gamma ($495.7K), the regime that mechanically reinforces pinning by inducing dealers to buy weakness and sell strength near heavy-OI strikes. Max pain identifies the strike at which the aggregate dollar value of all outstanding options contracts would expire with the least total intrinsic value, a gravitational reference rather than a price target.
HALO Strategy Implications at the Current Max Pain Level
With spot 3.5% from the $65.00 max-pain level and Halozyme Therapeutics, Inc. in a positive-gamma regime, where dealer hedging mechanically pulls spot toward heavy-OI strikes, strategy selection turns on cycle position and dealer positioning. Iron condors and credit spreads centered near the max-pain strike capture the typical end-of-cycle convergence when the regime supports pinning; ratio backspreads or directional debit structures fit names where catalyst flow is likely to overwhelm the hedging-driven pull. The gamma-exposure page shows the per-strike dealer book that determines whether hedging will reinforce or fight the pin.

Frequently asked HALO max pain analysis questions
- What is the current HALO max pain strike?
- As of May 15, 2026, Halozyme Therapeutics, Inc. (HALO) max pain sits at $65.00, which is 3.5% below the current spot price of $67.39. Max pain identifies the strike at which aggregate option-buyer payouts at expiration are minimized; it is a gravitational reference, not a price target. A 3.5% gap is close enough that a routine end-of-cycle gamma roll could pull spot toward the level, but far enough that catalyst-driven flow typically dominates.
- Does HALO pin to its max pain strike at expiration?
- HALO is currently in positive dealer gamma, the regime that mechanically reinforces pinning. Dealers hedging long-gamma books buy weakness and sell strength near high-OI strikes, which pulls spot toward those levels into expiration. Total open interest across HALO (17.6K contracts) is one input to how plausible a clean pin is - heavier total OI concentrated at fewer strikes raises the probability; thin OI spread across many strikes lowers it. Pinning is strongest in heavily-traded names with large open-interest concentrations at high-OI strikes during the final week of an OPEX cycle. Whether HALO actually pins on a given expiration depends on the OI distribution, the dealer-gamma sign, and the absence of catalyst-driven moves that overwhelm hedging-driven flow.
- How is HALO max pain calculated?
- Max pain is computed by summing the dollar value of all in-the-money options at each candidate settlement strike across listed expirations, then selecting the strike that minimizes total intrinsic-value payout to option buyers. The calculation uses the full open-interest distribution and weighs both calls and puts. HALO put/call OI ratio is 0.38 - call-heavy, which biases the max-pain calculation toward strikes above current spot when the call OI concentrates there.
