Chubb Limited — Where open interest creates price support and resistance
Chubb Limited (CB) is a Financials stock with actively traded listed options. Open interest concentrates at the $300 put wall (0.3K contracts) and $335 call wall (1.5K contracts) — 8.8% below and 1.9% above spot. Dealer hedging flows at these levels tend to dampen directional moves, reinforcing the wall corridor. This setup is more supportive of premium selling inside the wall range. See Strategy Builder for trade setups.
Where options dealers' hedging flows create support and resistance — max pain at $315.
These levels show where price may find support or resistance based on open interest positioning. Large put walls can act as magnets; call walls can cap upside.
Use wall levels to pick strikes — sell puts near put walls, sell calls near call walls.

Walls are based on current OI positioning and can shift as traders open/close positions. GEX assumes most OI is dealer-held — retail-heavy OI produces less hedging flow. Treat as context, not prediction.
Walls from nearest liquid expiry — these reflect short-term hedging activity and may not represent longer-term positioning.

Chubb Limited's current open interest profile shows relatively light concentration on both sides — put activity at $300 (280 contracts) and calls at $335 (1.5K) are below average for this expiration cycle. Scattered open interest means dealer hedging flows are less concentrated, reducing the "wall" effect that typically pins price within a range. Premium sellers should treat current support and resistance levels as softer than usual — wider stop losses and smaller position sizes are appropriate until open interest builds at specific strikes.
Chubb Limited's current options landscape shows put support concentrated at $300 (280 contracts) with call resistance at $335 (1.5K). This creates a $300–$335 trading corridor that dealer hedging activity naturally reinforces. Compare this wall-to-wall range with the Expected Move to see how volatility-based ranges align with open interest boundaries.
Chubb Limited's net gamma exposure is +1.5B (positive gamma regime), with the GEX flip point at $320.00. In a positive gamma environment, dealers are positioned so that they buy shares when price dips and sell when it rallies — effectively dampening volatility. This mean-reverting behavior is the best backdrop for premium selling: short strangles, iron condors, and credit spreads all benefit from the natural volatility compression that positive GEX creates. As long as price stays above the GEX flip point, this supportive environment tends to persist.
Chubb Limited's strongest put wall (support) is at $300 with 280 open interest contracts, and the primary call wall (resistance) is at $335 with 1.5K contracts. This creates a trading range of $300–$335. Call-side open interest dominates, creating stronger overhead resistance than downside support.
Open interest walls represent concentrations of options positions at specific strikes. When dealers hold these positions, they must hedge by buying or selling shares as price approaches wall levels, creating natural support (put walls) and resistance (call walls). Chubb Limited currently has positive gamma exposure, which means dealer hedging reinforces these wall levels — buying dips near put walls, selling rallies near call walls. This creates a mean-reverting, range-bound environment that benefits premium sellers.
Use the put wall at $300 as support for put credit spreads and the call wall at $335 as a ceiling for call credit spreads. The wall-to-wall range defines your expected trading corridor. Wall data is most useful for strike selection — placing short strikes at or outside major open interest levels means your trade has dealer hedging flows working in your favor. Monitor daily for wall migration as open interest shifts.
Chubb Limited has 5.40x more call open interest than put open interest at the primary wall levels. Call-heavy positioning can indicate bullish speculative interest (traders buying calls expecting upside) or heavy covered-call writing by shareholders. For premium sellers, this means call-side resistance is likely stronger than put-side support — call credit spreads above the $335 wall may benefit from heavier dealer selling pressure, while put-side trades have less concentrated support to rely on.
