Resmed (RMD): An investor bought 2,250 November 55 puts for $2.55 and sold an equal number of November 45s for $0.20. The put spread cost $2.35 and will earn profit of 325 percent if the shares close at or below $45 on expiration. It's probably being used as a protective strategy. RMD rose 0.15 percent to $56.

iShares U.S. Real Estate exchange-traded fund (IYR): Some 31,000 October 62 puts were sold for $0.10 and an equal number of November 61 puts were bought for $0.54. Volume was below open interest in the 62s, so it appears that a protective strategy was rolled forward in time and down in price. IYR rose 0.03 percent to $64.63.

Arkansas Best (ABFS): Some 2,500 November 25 calls were purchased, mostly for $1, as investors continue to build long positions in the trucking stock. ABFS rose 1.52 percent to $22.64.
