In recent years there has been a significant growth of interest in the incorporation of historical series of variables related to stock prediction into mathematical models or computational algorithms in order to generate predictions or indications about expected price movements. We evaluate ROLLS-ROYCE HOLDINGS PLC prediction models with Modular Neural Network (Speculative Sentiment Analysis) and Lasso Regression1,2,3,4 and conclude that the LON:RR. stock is predictable in the short/long term. According to price forecasts for (n+16 weeks) period: The dominant strategy among neural network is to Sell LON:RR. stock.

## Key Points

1. Can we predict stock market using machine learning?
2. Can machine learning predict?
3. How useful are statistical predictions? ## LON:RR. Target Price Prediction Modeling Methodology

Stock market or Share market is one of the most complicated and sophisticated way to do business. Small ownerships, brokerage corporations, banking sector, all depend on this very body to make revenue and divide risks; a very complicated model. However, this paper proposes to use machine learning algorithm to predict the future stock price for exchange by using open source libraries and preexisting algorithms to help make this unpredictable format of business a little more predictable. We consider ROLLS-ROYCE HOLDINGS PLC Stock Decision Process with Lasso Regression where A is the set of discrete actions of LON:RR. stock holders, F is the set of discrete states, P : S × F × S → R is the transition probability distribution, R : S × F → R is the reaction function, and γ ∈ [0, 1] is a move factor for expectation.1,2,3,4
