“Understanding Stock Price Prediction with Regression Models: A Practical Guide”

Abstract: Predicting stock prices accurately is a challenging yet crucial task for investors and financial analysts. In this article, we delve into the practical implementation of a regression model for stock price prediction using Python. We explore the steps involved in data preparation, model training, and prediction, providing insights into the process and its implications.

Introduction: Stock price prediction is fundamental in financial markets for making informed investment decisions. Regression models offer a systematic approach to forecast stock prices based on historical data. In this article, we illustrate the application of regression models in predicting stock prices using Python programming language.

Data Collection and Preparation: We begin by collecting historical stock data using Yahoo Finance API. For demonstration purposes, we choose Apple Inc. (AAPL) as our target stock. The data is then preprocessed to extract relevant features, such as closing prices, and transformed for analysis.

Model Building with Regression: We utilize the Prophet library for time series forecasting and prepare the data accordingly. After processing the data, we implement a regression model, initializing weights randomly and defining input features. The model is trained using forward and backward propagation techniques, adjusting weights iteratively to minimize errors.
