Abstract
Stock price prediction is considered as an important task and is of great at-
tention as predicting stock prices successfully may lead to attractive profits
for investors. Information Technology Sector of S&P 500 is one of the most
sought after business segments in S&P 500 and is one of the most attracting
areas for many investors due to high percentage annual returns on invest-
ment over the years. We used Microsoft Corp. (MSFT), one of the leading
companies of the Information Technology Sector Index of S&P 500 informa-
tion to build a non-linear real data-driven analytical model which accurately
predicts the Weekly Closing Price (WCP) of the stock with predictive accu-
racy of 99.3% using six financial, four economic indicators and their two way
interactions as the attributable entities that drive the stock returns. We rank
the statistically significant indicators and their interactions based on the per-
centage of contribution to the WCP of the stock that provides significant in-
formation for the beneficiary of the proposed predictive model. We present a
unique way for feature selection when multicollinearity presents in the mul-
tiple regression dataset using L1-regularization based on supervised machine
learning algorithm.

1. Introduction
Investors are highly attracted to the stock market due to unlimited profit return
possibilities. However, high returns are possible at a cost of high risk, thus, a
stock market is called risk-return trade-off [1]. The fluctuations of stock prices
