WMT is trading over 5% higher today be in on rumors of new services, or possibly buying TikToc. Doesnt matter. Whats interesting is there are a LOT of call options sitting >=140 strike, with another 240k calls trading so far today. Its 11AM EST.
It appears the gamma could fuel a move up toward $160, this map likely changes with tomorrows update, due to all that flow trading today.
