Even though there are myriad complex methods and systems aimed at trying to forecast future stock prices, the simple method of linear regression does help to understand the past trend and is used by professionals as well as beginners to try and extrapolate the existing or past trend into the future Linear Regression. Forecasting in Excel can be done using various formulas. One of the most commonly used formulas is the FORECAST.LINEAR for Excel 2016, and FORECAST for earlier versions. Although Excel still supports the FORECAST function, if you have 2016 or later, we recommend updating your formulas to prevent any issues in case of a function deprecation In order to predict future values, we need to isolate the trend. Then the trend can be extrapolated by a simple linear regression. Finally, seasonality can be factored back into the data. Using Excel's Forecast Sheet.
