Scanning through Barchart.com data for unusual options activity midway through Friday's trading, I noticed that two of the country’s largest recreational vehicle (RV) manufacturers had put options in the top 100.
The 20th most unusually active put option, with a volume of 974 against open interest of 136, is Thor Industries (THO), the world’s largest manufacturer of RVs. The 32nd most unusually active put option is Winnebago (WGO), with a Vol/OI of 5.26x.
