Many translated example sentences containing "expected order value" – German-English dictionary and search engine for German translations.Portfolio Return is calculated using the formula given below. Calculate Expected Return of portfolio. Apart from calculating the expecting return, the investor is also interested in determining the risk associated with each of the investment assets before investing in a specific asset.

If we take an example, where each of the assets of two different portfolios shows the following returns, respectively five years:. Whereas, each component is scrutinized the risk involved in it, based on the yearly deviation from the average expected return.

And you would also realize components of Portfolio A contains 5 times more risk than the portfolio component B.

Standard deviation states the level of variance from the average value. The formula for different probable returns through which we calculate the expected return for an investment which is calculated in the following steps:.

Step 1 : Initially, we need to determine how much we are going to invest and worth of the investment at the beginning of the investment.

Step 3 : Now, calculate the return based on the asset value at each probability at every initial phase and end of the period.

Step 4 : Finally, the expected return of an investment which we obtain at different probable returns is the sum of the product of each probable return and the corresponding probability of given asset.

The various steps by which we can calculate the expected return of portfolio which is an extension of the expected return of investment, here we give more emphasis on the weighted average of returns of each investment in the portfolio and it is calculated as follows:.

Step 1 : Initially, we need to determine an amount which we are going to invest at the start of the period. Step 2 : In the next step, we need to determine the weight of each asset form the portfolio which is denoted as w.

Step 3 : Finally, the expected return of a portfolio with varying returns is calculated as a sum of the product of varying returns of each of the asset form the portfolio along with their respective weight as specified below:.

Expected return plays a vital role in determining the overall return of the portfolio, it is widely used by the investors to anticipate the profit or loss may have while investing in it.

Based on the expected return formula an investor can decide whether he should continue to remain invested in the given probable returns.

Moreover, an investor can also give more emphasis on the weight of an asset whether any sort of tweaking is required. Apart from that investor can also use the expected return formula for ranking purposes and further can decide on the basis ranking whether they need to keep investing in the same asset.

More the expected return of an asset better is the asset. One natural question to ask about a probability distribution is, "What is its center?

Since it measures the mean, it should come as no surprise that this formula is derived from that of the mean. To establish a starting point, we must answer the question, "What is the expected value?

Let's say that we repeat this experiment over and over again. Over the long run of several repetitions of the same probability experiment, if we averaged out all of our values of the random variable , we would obtain the expected value.

In what follows we will see how to use the formula for expected value. We start by analyzing the discrete case. Given a discrete random variable X , suppose that it has values x 1 , x 2 , x 3 ,.

The expected value of X is given by the formula:. Using the probability mass function and summation notation allows us to more compactly write this formula as follows, where the summation is taken over the index i :.

This version of the formula is helpful to see because it also works when we have an infinite sample space. This formula can also easily be adjusted for the continuous case.

Flip a coin three times and let X be the number of heads. The only possible values that we can have are 0, 1, 2 and 3. Use the expected value formula to obtain:.
