Portfolio Optimization is an essential aspect of modern investing, and Modern Portfolio Theory (MPT) is a well-known approach to achieve an optimal portfolio. In this article, we will walk through a Python Portfolio Optimization script that demonstrates how to optimize a portfolio of stocks using MPT. We will use Yahoo Finance data and the Scipy […]

In this blog article, we will demonstrate how to calculate the Value at Risk (VaR) for a portfolio of stocks using the parametric method, also known as the variance-covariance method. The parametric method estimates VaR by assuming that portfolio returns follow a normal distribution. We will use Python and the yfinance library to download historical […]

In this blog post, we will demonstrate how to perform Value at Risk (VaR) calculations using the historical method for a portfolio of stocks. We’ll use Python and the yfinance library to download historical stock price data and then calculate VaR for an equally weighted portfolio. Setting Time Range and Tickers First, let’s set the […]

In this blog post, we will demonstrate how to perform a Value at Risk (VaR) simulation based on the Monte Carlo Method for a portfolio of stocks using Python and the yfinance library. We will use historical stock prices to calculate the expected return and standard deviation of the portfolio, and then run a Monte […]

In this blog post, we will demonstrate how to download historical stock prices using the yfinance library and Python, and then export to Excel file. Automating the yfinance export to excel process can streamline your financial data workflow. We will create a list of stock tickers, define a time range, download the closing prices for […]
