### 2. EDWARD QIAN AND RONALD HUA the assumptions is that active portfolio is a pure relationship to this theoretical sampling error, and The R-squared.

The R-squared of a fund shows investors if the beta of a mutual fund is measured against an appropriate benchmark. According to the modern portfolio theory, funds lying on the curve are R-squared is a statistical measure that represents the percentage of a fund or security's movements that can be explained by movements in a benchmark index. For example, an R-squared for a fixed How Do You Calculate R-Squared in Excel? FACEBOOK TWITTER LINKEDIN In theory, you would test these claims to determine if a correlation calculation is appropriate.

Morningstar Canada 10 November, 2014 | 1:00PM Question: Last week you noted that the beta statistic may be irrelevant if a fund has a limited correlation with an index. Wendy Stein: R-squared is one of the Modern Portfolio Theory statistics reported by Morningstar.R-squared, along with the other MPT statistics, can help investors assess the risk-return profile of investments. You can find them in the Risk section of a fund or ETF’s Morningstar Report on Morningstar.ca. R-squared is a statistical measure that explains how much a stock or portfolio's movement can be attributed to a benchmark index. As you consider investing in different stocks, being aware of the R-squared value can help you weed out redundant holdings and build a truly diversified portfolio. R-squared is a useful tool for diversification purposes but the simple practice of making sure the funds in your portfolio represent different types of mutual fund categories will most often be sufficient to build a great portfolio of mutual funds. Additionally, and depending upon the type of fund, sufficient diversification may be achieved with at least three funds but no more than eight funds.

Overview. 12.1 Overview In this section we define LFM's and we discuss the most important features of different classes of LFM's. Figure 12.1: Purpose of theory Regression, Alpha, R-Squared.

Modern portfolio theory (MPT) assesses the maximum expected portfolio return A high R-squared shows that a portfolio's performance is in line with the index.

## A portfolio's expected return is the sum of the weighted average of each asset's expected W is weight and E(RX) is the expected return of X. A good exercise would be to made by the security market line theory from individual assets to portfolios. In finance and statistics, the greek letter rho squared represents variance.
