R squared (R2) or coefficient of determination is a statistical measure of the goodness-of-fit in linear regression models. While its value is always between zero and one, a common way of expressing it is in terms of percentage. This involves converting the decimal number into a figure from...

More specifically, R-squared gives you the percentage variation in y explained by x-variables. The range is 0 to 1 (i.e. 0% to 100% of the variation in y can be explained by the x-variables). The coefficient of determination, R2, is similar to thecorrelation coefficient, R. Thecorre...
Let’s start by defining how R-squared can be too high. R-squared is the percentage of the dependent variable variation that the model explains. The value in your statistical output is an estimate of thepopulationvalue that is based on yoursample. Like otherestimatesin inferentialstatistics, yo...

R-squared is a raw measurement that does not take into account the size of a stock or portfolio. Adjusted R-squared, on the other hand, measures the degree to which a stock’s price movements link to broader market performance. It also takes into account the size of the company. ...

there are many methods to compute them (R actually has 7 methods to compute the quantiles!). However, the methods presented here and in the article “descriptive statistics by hand” are the easiest and most “standard” ones. Furthermore, results do not dramatically change between the two me...
you would want the fund’s R-squared value to be as high as possible since its goal is to match—rather than trail—the index. On the other hand, if you are looking for actively managed funds, then a high R-squared
