There are 2 break-even points for the strip position. The breakeven points can be calculated using the following formulae. Upper Breakeven Point = Strike Price of Calls/Puts + Net Premium Paid; Lower Breakeven Point = Strike Price of Calls/Puts - (Net Premium Paid/2) Example. Suppose XYZ stock is trading at $40 in June.
