Different machine learning algorithms are discussed in this literature review. These algorithms can be used for predicting the stock market. The prediction of the stock market is one of the challenging tasks that must have to be handled. In this paper, it is discussed how the machine learning algorithms can be used for predicting the stock value. We evaluate SPIRE HEALTHCARE GROUP PLC prediction models with Statistical Inference (ML) and Pearson Correlation1,2,3,4 and conclude that the LON:SPI stock is predictable in the short/long term. According to price forecasts for (n+1 year) period: The dominant strategy among neural network is to Buy LON:SPI stock.

Keywords: LON:SPI, SPIRE HEALTHCARE GROUP PLC, stock forecast, machine learning based prediction, risk rating, buy-sell behaviour, stock analysis, target price analysis, options and futures.

## Key Points

1. Which neural network is best for prediction?
2. What is prediction model?
3. What is statistical models in machine learning? ## LON:SPI Target Price Prediction Modeling Methodology

The study of financial markets has been addressed in many works during the last years. Different methods have been used in order to capture the non-linear behavior which is characteristic of these complex systems. The development of profitable strategies has been associated with the predictive character of the market movement, and special attention has been devoted to forecast the trends of financial markets. We consider SPIRE HEALTHCARE GROUP PLC Stock Decision Process with Pearson Correlation where A is the set of discrete actions of LON:SPI 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

## Conclusions

SPIRE HEALTHCARE GROUP PLC assigned short-term Ba1 & long-term Ba3 forecasted stock rating. We evaluate the prediction models Statistical Inference (ML) with Pearson Correlation1,2,3,4 and conclude that the LON:SPI stock is predictable in the short/long term. According to price forecasts for (n+1 year) period: The dominant strategy among neural network is to Buy LON:SPI stock.
