RMD put/call walls show support near $200 and resistance near $260.
ResMed Inc. — Where open interest creates price support and resistance
RMD put/call walls identify the strike prices with the highest open interest concentration, which often act as support and resistance levels for the underlying stock. The strongest put wall sits at $200 (support) and the strongest call wall at $260 (resistance).
Premium sellers use these wall levels to position short strikes near areas of high open interest, where price tends to slow or reverse. The current gamma exposure regime is negative, which can amplify moves and increase directional risk. Max pain — the strike where total option losses are minimized — sits at $230.
Wall levels are derived from current open interest positioning and update daily after market close. They can shift as options traders open or close positions. For context on how RMD options are priced overall, see the RMD IV analysis and RMD VRP analysis.
ResMed Inc. (RMD) is a Healthcare stock with actively traded listed options. Open interest concentrates at the $200 put wall (0.4K contracts) and $260 call wall (0.3K contracts) — 9.9% below and 17.1% above spot. Dealer hedging at these levels amplifies moves rather than containing them — wall boundaries are less reliable. Wider spreads or defined-risk setups may be more appropriate in this gamma regime.

Where options dealers' hedging flows create support and resistance — max pain at $230.
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.

ResMed Inc.'s current open interest profile shows relatively light concentration on both sides — put activity at $200 (368 contracts) and calls at $260 (299) 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.
ResMed Inc.'s current options landscape shows put support concentrated at $200 (368 contracts) with call resistance at $260 (299). This creates a $200–$260 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.
ResMed Inc.'s gamma exposure has turned negative (-0.0B), indicating that dealer hedging is now amplifying price moves rather than dampening them. When GEX is negative, dealers must sell into declines and buy into rallies — the opposite of the supportive mean-reverting flow that premium sellers prefer. The GEX flip point at $230.00 is the level where this regime would reverse. Until price reclaims that level, premium sellers should use defined-risk strategies (credit spreads over naked positions) and consider reducing position sizes to account for the elevated move amplification.
ResMed Inc.'s options-defined support sits at the $200 put wall (368 OI), and resistance at the $260 call wall (299 OI). The full range is $200–$260, defined by the strikes where dealer hedging is concentrated.
ResMed Inc.'s strongest put wall (support) is at $200 with 368 open interest contracts, and the primary call wall (resistance) is at $260 with 299 contracts. This creates a trading range of $200–$260. Open interest is relatively balanced between puts and calls, creating symmetric dealer hedging pressure.
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). ResMed Inc.'s gamma exposure is currently negative, which means dealer hedging can actually amplify moves through wall levels rather than defending them. In negative GEX environments, walls are less reliable as support/resistance, so premium sellers should use defined-risk strategies.
ResMed Inc.'s net gamma exposure is -0.0B, meaning dealers are net short gamma and must hedge in the same direction as price movement — selling into declines and buying into rallies. This amplifies volatility rather than dampening it. The GEX flip point at $230.00 is where this dynamic reverses. Negative GEX environments typically produce larger daily moves, which is unfavorable for premium sellers. Consider using credit spreads instead of naked positions, or wait for GEX to turn positive before adding new short premium exposure.
ResMed Inc.'s $200–$260 range spans 27.0%, wider than average. This spread suggests open interest is distributed across distant strikes, which can mean the market is pricing in a larger potential move — possibly around an upcoming catalyst like earnings or an industry event. For premium sellers, wider ranges mean wall support and resistance are farther from current price, providing more breathing room but also less concentrated dealer hedging at any single level.
With earnings approximately 11 days away, ResMed Inc.'s current wall structure should be interpreted with caution. Earnings gap moves routinely exceed the wall-to-wall range — the $200–$260 corridor is based on current open interest, which will shift dramatically around the announcement as traders close pre-earnings hedges and new post-earnings positions are established. Premium sellers carrying positions into the earnings event should assume the walls may not hold and size accordingly.
With negative gamma exposure, favor defined-risk credit spreads over naked positions — place short strikes at wall levels but use wings to cap risk in case walls break. 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.
