The speaker demonstrates a 76 60 76 7690 put butterfly with a 650 debit. By calculating the number of steps between strike prices (60 to 65 is one step, 65 to 70 is two steps, 70 to 75 is three steps), the trader squares the number of steps (3 * 3 = 9) to determine the number of embedded butterflies. The trader then adjusts the position based on the index movement, selling butterflies when the index drops to 7665 and maximizing the 70-75-80 butterfly when the index rallies to 7675. This strategy aims to capture the maximum value of embedded butterflies as the index moves around the strike prices.
