I saw this too. I think someone sold the 62.50 puts and used the proceeds to buy the 72.50 calls, while also selling the 77.50 calls. The sold call options will cap the traders profits, but will also offset some of the cost if falls below the 62.50 strike price. The trader would have pocketed money to put this trade on, depending on how many call options they sold.
That's May month,,, i wonder if parties selling all these calls are effectively short the stock.... could short squeeze come about from this... they aren't appearing to buy the stock to offset risk selling calls
