Stock market forecasting is considered to be a challenging topic among time series forecasting. This study proposes a novel two-stage ensemble machine learning model named SVR-ENANFIS for stock price prediction by combining features of support vector regression (SVR) and ensemble adaptive neuro fuzzy inference system (ENANFIS).** We evaluate Exelixis prediction models with Deductive Inference (ML) and Lasso Regression ^{1,2,3,4} and conclude that the EXEL stock is predictable in the short/long term. **

**According to price forecasts for (n+4 weeks) period: The dominant strategy among neural network is to Hold EXEL stock.**

## EXEL Target Price Prediction Modeling Methodology

As part of this research, different techniques have been studied for data extraction and analysis. After having reviewed the work related to the initial idea of the research, it is shown the development carried out, together with the data extraction and the machine learning algorithms for prediction used. The calculation of technical analysis metrics is also included. The development of a visualization platform has been proposed for high-level interaction between the user and the recommendation system. We consider Exelixis Stock Decision Process with Lasso Regression where A is the set of discrete actions of EXEL 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 Î³ ∈ [0, 1] is a move factor for expectation.^{1,2,3,4}

## Conclusions

Exelixis assigned short-term B1 & long-term B2 forecasted stock rating.** We evaluate the prediction models Deductive Inference (ML) with Lasso Regression ^{1,2,3,4} and conclude that the EXEL stock is predictable in the short/long term.**

**According to price forecasts for (n+4 weeks) period: The dominant strategy among neural network is to Hold EXEL stock.**
