R-Squared: Definition, Interpretation & Calculation

WebFeb 27, 2024 · R-squared only measures the degree to which a stock moves in line with the markets, not the degree to which a stock moves in a favorable or unfavorable way. Even if a stock’s R-squared reading is high, it may not be a good investment if its price is too high relative to the rest of the market. WebTherefore, the quadratic model is either as accurate as, or more accurate than, the linear model for the same data. Recall that the stronger the correlation (i.e. the greater the accuracy of the model), the higher the R^2. So the R^2 for the quadratic model is greater than or equal to the R^2 for the linear model.
