ResMed is trading at all-time highs, and one investor is apparently looking to protect those gains.
A trader bought 2,500 November 55 puts for $2.55, above the listed ask price at the time, and sold 2,500 November 45 puts for $0.20. This is clearly new positioning, as previous open interest at those two strikes was 20 and 0 respectively.
The trader is spending $2.35 to open this vertical spread. The sale of the lower-strike puts reduces the cost of the higher-strike purchase, though it caps gains once the stock is at or below $45. The maximum potential gain on the trade is $7.65, but the trader would face the obligation to buy shares if the stock falls below the lower strike.
Given how far ResMed has run, the put spread could well be hedging a long position rather than making an outright bearish bet. (See our Education section)
