Snapshot as of May 15, 2026.
- Spot Price
- $105.01
- Max Pain Strike
- $95.00

As of May 15, 2026, State Street SPDR Bloomberg Convertible Securities ETF (CWB) max pain sits at $95.00, which is below the current spot price of $105.01 (9.5% away). Spot sits 9.5% below max pain - the gap is wide enough that the pinning effect alone is unlikely to close it; expect catalyst flow, positioning unwinds, or rebalancing to drive the actual price path before any expiration pull. CWB trades in the standard mid-price band (spot $105.01), with listed strikes typically $1-$5 apart and balanced single-leg vs multi-leg flow. Total open interest across the listed chain is comparatively thin (3.3K contracts), so single-strike pinning is less reliable than it is for high-OI names. CWB is currently in negative dealer gamma (-$526.1K), a regime that amplifies directional moves rather than damping them, weakening the pin-toward-max-pain bias. 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.
CWB Strategy Implications at the Current Max Pain Level
With spot 9.5% from the $95.00 max-pain level and State Street SPDR Bloomberg Convertible Securities ETF in a negative-gamma regime, where dealer hedging amplifies directional moves and weakens any pin, 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 CWB max pain analysis questions
- What is the current CWB max pain strike?
- As of May 15, 2026, State Street SPDR Bloomberg Convertible Securities ETF (CWB) max pain sits at $95.00, which is 9.5% below the current spot price of $105.01. 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 9.5% gap is wide enough that the pinning effect alone is unlikely to close it; expect catalyst flow, positioning unwinds, or rebalancing to drive the price path before any expiration pull.
- Does CWB pin to its max pain strike at expiration?
- CWB is currently in negative dealer gamma, a regime that amplifies directional moves rather than damping them. The pin-toward-max-pain bias weakens here because dealer hedging adds momentum rather than mean reversion. Total open interest across CWB (3.3K 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 CWB 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 CWB 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. CWB put/call OI ratio is 27.37 - put-heavy, which biases the max-pain calculation toward strikes below current spot when the put OI concentrates there.
