| yly14 | thank you for the heads up, we'll definitely to looking closely to find WRONG questions at the exam!! |
| oluji | and hope to get credit for finding wrong questions :) |
| bmeisner | The negative is implied, cmon... Quite frequent to hear an OTM put referred to as a 25 delta put. Delta after all is just a measure of the likelihood that the option ends up in the money at expiration. 25% chance of the stock finishing below the strike based on the B-S model. That's quite obvious by the use of the cumulative standard normal probability distribution. It wouldn't make any sense if someone said there's a negative 25% chance of this option ending up in the money. |
| bbadger | Delta has 3 definitions. 1. chance the option expires in the money. 2. hedge ratio. 3. change in option price for a one tick (pip, dollar...) change in the price of the underlying. I never really think of delta as being + or -, though it'll prob be on the test. Also, call hedging is opposite, put is the same (i.e. buy calls, sell futures: buy puts, buy futures) |
