Dr. Jim starts off class by introducing Brittany to a new strategy - an Iron Fly. He informed her that an Iron Fly is similar to an Iron Condor EXCEPT that with an Iron Fly, the short strikes (call/put) are the same, and both will be ATM. Dr. Jim then guides Brittany through the platform to set up her first Iron Fly, and the expression on Brittany's face is priceless when she sees how her max profit and max loss change with this new strategy. To end the day, the two jump back into the material and learn a key takeaway regarding volatility -. This is largely driven by the simple fact of - when people buy stocks, their prices rise, and when people sell stocks, their prices fall.
