This blog wil give a clear and good understanding on how statistical techniques are performed in the field of stock market by highlighting the key characteristics or features, practical based applications and commonly used fearures or tools that provide support in data-driven trading and investing strategies.

Introduction

The stock market is very much uncertain as no one can predict what will happen in the future or in the coming days.

By examining the historical movement of prices, returns, and volume patterns, statistics helps the traders, investors and the people who are very much engaged with stock market to identify the trends, measure the level of risk and evaluate potential results. In today’s data-driven markets, statistical data analysis forms the core of technical based analysis and quantitative based trading. It also forms the foundation of risk management systems.

Applications of Statistical Data Analysis in the field of Stock Market and

trading

1. Understanding the pattern of market Various Statistical methods like mean, variance, and standard deviation are widely used for analyzing the prices of stocks and returns.
