A stock market index is a measurement of the value of a section in the securities exchange market whose information is publicly available. It plays a very vital role in decision making of investors. In this study, we are concerned with the Standard & Poor 500(S&P) market index data for the year 2007-2017 analyzed using several official statistical packages; timeSeries, forecast, ggplot2 and tabplot. The packages heavily aid in forecasting future prices of the market index.
