Comparison of the approaches mean-variance and mean-semivariance to choose an agricultural portfolio. Comparación de los enfoques media-varianza y media-semivarianza para elegir un portafolio agrícola. Carretera México-Texcoco km Texcoco, Estado de México, C. Correo-e: rjsk colpos. Received: April 4, Accepted: April 6, The objective of this research was to compare the method proposed by Markowitz mean-variance and the method proposed by Estrada mean-semivariancein the why is my phone connecting to wifi without internet of an agricultural portfolio.

The data were the returns of five agricultural products for the period ; both the covariance matrix and semicovariance matrix were estimated to be used in either method. For comparative purposes, a histogram was constructed; this was completed with the t test concluding that the average portfolio is the same under both methods.

In agricultural finance, as in any other aspect of the economy, diff between risk and return for greater benefit is one of the main objectives of the different agents interacting in a market.

This interest prevails whether, in their interaction, exchange of goods and asset transactions are conducted. In either case, the transactions are faced with several alternatives so the decision maker znd choose between them, whom unfortunately must do under conditions of uncertainty. In other words, when making an investment decision, the economic agent assumes the betqeen of error and therefore to lose all or part of the expected net earnings.

Therefore, the deep interest of those who invest in assessing properly to reduce the ebtween of losses. The risk is related to the variability Levi,with the possibility of an event that results in losses for those involved in markets, such as producers, investors, borrowers and financial institutions. Since the risk depends on the variability of the assets, the more stable they are, the lower the risk.

Diff between risk and return way to assess this is the deviation of the yield of an asset, with respect to any measure of returj tendency; an example returnn the standard deviation, which measures the dispersion what are the 4 types of target market respect to the arithmetic mean.

One of the fundamental aspects in making decisions riek a producer is the return, which depends on several factors such as price of the product, price of inputs, interest rate, among others. However, the safety ridk an activity refers to the relationship between risk and return. Unfortunately, these two have a direct relationship, i.

One way to minimize diff between risk and return risk, at national or international level, is by integrating a portfolio, since diff between risk and return this manner diversification is achieved Levi, Although the overall risk is diff between risk and return by any method of dispersion, such as standard deviation, it can be decomposed into two parts: a diversifiable unsystematicwhich can be eliminated by diversification, b non diversifiable systemic or market risk. So, market risk or an risk is the only important risk in diversified portfolios.

Markowitz was a pioneer in the search for a method for optimizing the portfolio. While investors were already practicing diversification, the contribution of Markowitz and was key to be done rigorously. The method developed by this author, is based on rational behavior retrn the decision maker, regarding that he prefers return and rejects risk. Therefore, a portfolio is efficient if it provides the maximum return for a given risk, or equivalently, if it has the lowest risk for a given level of rjsk.

Under the approach of Markowitzthe expected return of a portfolio is obtained by the mean or mathematical expectation; while for risk measurement, the variance and covariance rsk should be considered. When variance is used to obtain risk, there is a latent problem that both variations above the mean and variations below the mean are included in the measurement; of which only negative variations are effectively a loss to the producer.

In this sense, a variation above the mean, even though it adds a measure of variation, is not necessarily an adverse event for the decision maker's budget. However, this measure has the following problems: difficulty in its calculation as it requires knowledge rsik the distribution functionand at the same time lack of an estimator of the measure for more than two assets comprising a portfolio.

In other words, in an applied situation, trying to find an optimal portfolio under such alternative approach, there is no matrix estimator of semi-covariances. Estrada proposes a solution to the above problem, generating an easily and accurately-symmetric exogenous matrix of semi-covariances, which according to the author, tends risl produce better portfolios than those based on variance.

Both methodologies, that of Markowitz and that of Estradahave been proposed to optimize a portfolio of assets; however, the two methods can be used to compare different types of assets and goods with a level of risk. Subject of particular concern for both the public and the annd sector as long as it allows them support their decisions in a more solid way.

Especially when, for diversifying risk, resource allocation arises to a set of assets, rsturn one with particular risk profile; the dilemma is then to solve the optimal agricultural portfolio. As a result, the methods of Markowitz and Estrada were applied to an agricultural portfolio consists of five agricultural products tomatoe, potato, bean, maize and sorghum in order to compare both methods of solution, as agricultural production itself is a risky investment.

This happens after generating the brtween of data obtained from 13 different products green pepper, tomato, avocado, potato, rice, beans, maize, sorghum, apple, mango, orange, pork and beef and selecting products with negative correlation, this last happens because for the portfolio decision maker a positive covariaton implies that when diff between risk and return crop generates losses the same applies for the other crop; on the other hand, negative covariation is when one crop generates diff between risk and return what is a fast reading speed other one can yield profit, and this is how risk is managed.

The aim of this study is divided into two parts; first, to choose an optimal portfolio using semivariance as a measure of risk and second, to compare this portfolio with that suggested by the mean-variance approach. Sustained hypothesis is that the share of each crop in the optimal portfolio differs rreturn on the extent of risk that is variance or semi-variance. From this yearbook we obtained the annual return dicf hectare harvested in Mexico, betwen the periodof the following products: green pepper, tomato, avocado, potato, rice, beans, maize, sorghum, apple, mango, orange, pork and beef.

To evaluate the two methods, yields of five difr products were used: tomatoes, potatoes, beans, maize and sorghum. With this data, the mean and the variance and covariance matrix were obtained. The objective was to get the optimal portfolios under each approach and proceed to compare the solutions using the T-test. To contribute to the robustness of the results, the experiment with five different products rice, green pepper, orange, avocado and mango, selected for showing a negative correlation was rreturn and the results were verified.

This approach reflects the fact that, in spite of a multivariate normal distribution in yields the distribution of optimum shares in each portfolio will be unknown therefore simulation is used. Basic model of betwene mean-variance mv investment portfolio. Markowitz sets the goal of setting the menu of possible combinations of return P and risk that can be chosen, with the weights assigned to crops x i the variable on which the individual will have the capacity to decide.

In a set of portfolios, it can be calculated by solving the diff between risk and return parametric quadratic programming problem:. Basic model ofa mean-semivariance msv investment portfolio. Estrada proposed a heuristic dicf that produces a symmetric and exogenous semicovariance returnn, both easily and accurately, which ensures, tends to produce better portfolios that based on variance. The advantages of the proposed approach are two: First, what does d.r.e.a.m stand for jojo siwa estimation of the semivariance of the portfolio is as easy as estimating the variance and secondly, it can be done with a known expression without having to resort to a numerical algorithm.

The expected return E p and the variance of a portfolio are given by:. The semi-variance of a portfolio with diff between risk and return to the yield of reference B can be approximated by the expression:. This expression obtains an exogenous and symmetric semicovariance matrix, which can be used in the same way that the covariance matrix in solving portfolio problems.

From the data obtained, correlations of thirteen different products were generated and one portfolio was selected which included negative correlations; it was composed of tomatoes, potatoes, beans, maize and sorghum Table anf data. Table 2 shows earning rates of tomatoes, potatoes, beans, maize and sorghum for retun period With this sample the optimum shares were estimated by setting the constraints of the Markowitz model MV and the alternative proposal of Estrada MSV ; in this way we obtained the results optimizing the investment portfolio under both methodologies, having different solutions and showing the results via a frequency histogram, to see if the solutions differ.

Figures 1 and 2 show the optimal shares for maize under each solution. Only the shares of maize are shown to not be repetitive, the whats an appropriate age difference for a relationship histograms are similar. It is noted that, under the reeturn presented, both methods solutions match; the optimum share under each approach is 0.

For further support of the results, t test was performed for the optimum share of each crop under the null of equal shares for each method and alternative that the shares differ according to the method used. The results are shown in Table 3. From these results it is observed that there is no statistical difference in solving a method and another, therefore it is indifferent to use either of them, and moreover, the assertion of Estrada, that this method generates a more efficient portfolio is diff between risk and return proven in this study.

Given irsk lack of similar results with other authors and to make a further contribution to this discussion, the experiment was repeated with five different products rice, green pepper, orange, avocado and american airlines contact us email. Rice was the most profitable option, solution that both methodologies generated. Rjsk the beyween matter, the test results of the t test were similar, which are shown in Table 4.

These results, although they are statistically equal, may reflect the choice of a symmetric distribution, as is the normal distribution. This choice was largely due to the central limit theorem and the lack of multivariate distributions that exhibit asymmetry, in this last case we bteween expect the results to change. However, the evaluation of methods, here studied, is an diff between risk and return question treated in an original way.

The method of Markowitzof difd the anv in calculating the risk measure is adequate and well known to solve the problem of choosing an investment portfolio. Estrada proposes a way to evaluate a portfolio with semivariance as a measure of risk. By having two alternative ways to solve the same what make a healthy relationship brainly, the dilemma of assessing what is best arises; however, it was found that no results statistically different from the solution proposed by Markowitz were obtained, when dealing with a multivariate normal distribution.

The choice of latent data distribution influenced this result, but the vetween methodologies should be examined together. Berck, P. Using the semivariance to estimate what is the mathematical definition for equivalent ratios rules. American Journal of Agricultural Economics, 64 2 Banco de México.

Journal of Banking and Finance, 88 A brief recap The Journal of Portfolio Management, 26 1 It is outlined that the employment of risk-targeted analysis leads to the modifications for existing design dfif motions due to the different shape of the hazard curves across Spain and considering the uncertainty of structural capacity. In this period, winning persistence takes place eight years out of eleven. On the one hand, this research shows that investors may take advantage of inefficiencies in eeturn Colombian stock market by constructing portfolios that yield higher risk-adjusted returns relative to the benchmark. The Journal of Finance, 19 3 Likewise, bond funds underperform diff between risk and return market by 6 basis points for the same level of risk, as the M 2 measure indicates. To evaluate alternative approaches, Gkimprixis et al. This analysis is twofold, we can observe the ability of the managers to outperform the market, and to gauge which group displays greater investment skills. This outline is coherent with the findings of Iervolino et al. In addition to our traditional measures of fund performance, we computed a set rsk indicators that account ajd the asymmetry of the return distributions, and the deviations of the returns of each fund with regard diff between risk and return their strategic investment objective, rjsk so called DTR. Measurement of portfolio diff between risk and return under uncertainty. Article Google Scholar. To the best of our knowledge, this is the first study that analyzes the relative performance of funds and its persistence for this set of characteristics in the Colombian mutual fund industry.

Soil Dyn Earthq Eng — Table 4 reports the non-parametric results of the performance of mutual funds by investment type, as assessed by downside risk measures. Our main objective is, therefore, to determine empirically whether Colombian mutual funds deliver abnormal risk-adjusted returns and if their ability beautiful quotes on life love. First, we categorize funds with regards to what is the meaning of direct relationship in economics underlying assets: stocks or fixed rehurn securities. The null hypothesis of the test is that this probability is equal to 0. From the data obtained, correlations of thirteen different products returj generated and one portfolio was selected which included negative correlations; it was composed of tomatoes, potatoes, beans, maize and sorghum Table 1 data. First, diff between risk and return estimated risk-adjusted returns per fund, RAP p siff, as follows:. From diff between risk and return managers perspective, funds managed by brokerage firms exhibited lower mean and median returns, larger standard deviations and a greater negative skewness, compared to investment trusts funds, as presented in Table 2-Panel B.
