    Finance and capital markets on Khan Academy: Interest is the basis of modern capital markets. Depending on whether you are lending or borrowing, it can be viewed as a return on an asset (lending) or the cost of capital (borrowing). This tutorial gives an introduction to this fundamental concept, including what it means to compound. It also gives a rule of thumb that might make it easy to do some rough interest calculations in your head.
    About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

    Can you make a video on options pricing models? For example, using binomial models. You can't do American options and dividend options as accurately with black scholes. You can also simulate the implied volatility with models.

    Yes, the variables d1 and d2 are derived from the geometric Brownian motion which is lognormally distributed.

    Hi, thank you for the explanation! Can you show why d1 is the conditional probability of how deep in the money the europ. call is? I mean, in the form of standardized Z-value of normal distribution, derived from a lognormal (in the usual form of x minus mean/stand. dev.).

      I have a doubt,What about the call option price in case of OTC .
      Here we don't know how much price call option is trading in the market....do we need to match with similar options on exchange??
      Else we have two variables and can't solve for implied volatility.

    To put it in very raw term, can we say that what IV is, is actually the premium which markets pay for the option. This is derive by getting the market price of the option and minus the knowns (Stock Price, exercise and etc). By doing so, we also will be able to figure out if market is paying more or less for a given assumption on volatility (assuming we have one). And basically we are trading the premium of the option? Suppose everything else stays constant.

  • @enteradj

    People trade options on implied volatility, does that mean that implied volatility would have its own implied volatility?

  • @HKHasty
    @HKHasty 4 года назад +2

    Isn't the logic of calculating volatility from B.S. formula circular?
    Options traders will make an assumption about volatility. An option's price is calculated accordingly. Then stock traders will use the option price to back-calculate volatility.

    I can identify the consistency everyone is missing, the stock price change in % and consistent time to expiration, and consistent back log the equally change in % to strike price will be worth the same amount every time.

    He keeps saying if I have these 6 inputs, but there are only 5 inputs to derive the 6th value. The 5 inputs are Stock px, Strike px, Time, Risk Free Rate, Volatility, the output is Options px.

    Is exercise price means amount of premium paid??

    • @simcityz
      @simcityz 4 года назад +1

      Strike price and exercise price have both the same meaning it is the fixed price or amount of cash that you pay to counterparty as a call option holder in exchange for receiving the stock from the counterparty if you decide to exercise the option.
      If you are put option holder then exercise price guarantees the amount of cash you receive from counterparty in exchange for giving your stock to counterparty if you decide to exercise the option.
      Premium is the price that you must pay intially to counterparty in order to receive this insurance and right but not obligation to exercise the option if it is beneficial to you. Thus, the premium is the price of creating the contract (option) between insurance buyer (option holder) and insurance seller (option writer) and it is paid from buyer to seller.
      It is easier to understand it when you think about normal insurance company that collects payments (premium) from you intially in order to establish the insurance contract between you and the company. Then you receive the insurance that protects you from unfortunate events. The insurance company is obligated to fullfill their side of contract e.g. recovering certain amount of costs related to damages. However, if you do not need/use the insurance then the insurance company keeps your initial payment (premium) as a profit. Similar logic applies to derivatives markets and options with some practical differences of course.

    NOTE: The market does not say the correct price. The price comes from the exchange of money between investors. The market price is a reflection of the exchange of money between investors--the Ponzi process.

    Hi everyone, can someone ask this important question ,please ?:
    If you buy a call/put option that only has intrinsic value, then you can almost forget about Theta an IV because the option price movement will not be affected by them?
    is that right? :
    Theta and IV only applies to the extrinic value part and not to the intrinsic value part of the price of the option?
    Else, if you buy a call/put option with both intrinsic and extrinsic value, but, the amount of intrinsic value is bigger than the extrinsic value , you can only lose money if your option ends OTM?I mean, even if end up losing all the extrinsic value, because your option ends ITM (you get right the direction of the stock movement) , still has intrinsic value (and bigger than the one it had when you bought it)
    You can only lose (because of theta and IV) the extrinsic value part , not more than that?
    Thanks in advance

    Ones off there main reasons I don't watch Khan academy videos is because the speaker sal Khan repeats every sentence 2-3 times. Is really irritating to listen. No wonder his videos have such a low likes to views ratio
