How do you calculate a replicating portfolio?
Replicating portfolio, contd. = (cu − cd)er + ucd − dcu (u − d)er = (er − d)cu + (u − er)cd (u − d)er . c = pcu + (1 − p)cd er . Based on binomial model for share prices.
What would be replicating portfolio of bonds and stocks that could generate the same payoff of option?
The replicating portfolio to value a put option is a short position in the stock and purchase of a bond. This portfolio is called a replicating portfolio because if you sold the stock now (quantity discussed below) and lent the present value of the stock, your payoff will exactly match the payoff from the put option.
What is binomial model for option valuation?
The binomial option pricing model is an options valuation method developed in 1979. The binomial option pricing model uses an iterative procedure, allowing for the specification of nodes, or points in time, during the time span between the valuation date and the option’s expiration date.
What is the intrinsic value of the call?
The intrinsic value of both call and put options is the difference between the underlying stock’s price and the strike price. In the case of both call and put options, if the calculated value is negative, the intrinsic value is zero.
Why do we use replicating portfolio?
The great benefit of replicating portfolios lies in the speed of recalculating the effects of financial market developments. Replicating portfolios allow insurance companies to create an integrated view of assets and liabilities that can be used to perform a detailed analysis of asset-liability management (ALM) risks.
What is the purpose of a replicating portfolio?
Replicating portfolios enable separation of investment and insurance business for management purposes. 3. There may not be actual assets or actively traded assets that replicate long-term or exotic features of insurance liabilities.
Why do we replicate portfolio?

Building an effective replicating portfolio may force the trader to get involved in an active portfolio management.
How do you value an American call option?
The value of an American call option equals the value of a European call option assuming both calls have the same strike price and expiration date.
How is option delta calculated?
To calculate position delta, multiply . 75 x 100 (assuming each contract represents 100 shares) x 10 contracts. This gives you a result of 750. That means your call options are acting as a substitute for 750 shares of the underlying stock.
How do you find the intrinsic value of a call option?
Call Option Intrinsic Value = Current Stock Price – Call Strike Price. Intrinsic value is the difference between the underlying price and the strike price, to the extent that this is in favor of the option holder.
How do you find the intrinsic value of an option?
- In the money call options: Intrinsic Value = Price of Underlying Asset – Strike Price.
- In the money put options: Intrinsic Value = Strike Price – Price of Underlying Asset.
How many shares will I buy or sell to replicate portfolio?
The number of shares you will buy or sell (short) to create a replicating portfolio will be based on the hedge ratio or option delta. The hedge ratio or option delta is arrived at by taking the spread of the option values divided by the spread of the stock prices being considered.
What is the replicating portfolio approach to value options?
The replicating portfolio approach to valuing options finds a portfolio of assets that has the same payoff as the option on expiry. We then value the portfolio today to account for the discounting effect of time.
How do you find the replicating portfolio from a tree?
Find the replicating portfolio at each nodes of the tree. Solution for a.) First we need to calculate the first period probabilities: The second-period probabilities are the same since R = .01 is constant in both periods.
How do you value options in a portfolio?
The key to understanding valuing options using the replicating portfolio approach, risk-neutral approach or the binomial tree approach is to understand the following pieces: Two assets that provide the same cash flow must logically have the same value/price.
