TSLA, DJT, VTI (Standard Deviation, Variance, Correlation, Covariance, and Beta)

This video uses historic stock data from finance.yahoo.com for Tesla Inc. (TSLA), Trump Media
& Technology Group Corp (DJT), and Vanguard Total Stock Market Index Fund ETF Shares (VTI) to show how to use Excel function to calculate Rate of Return, Variance, Standard Deviation, Correlation, Covariance, and Beta. The Vanguard Total Stock Market Index is a proxy for the Wilshire 5000 which is a broader US stock index than the S&P 500.

The problem is a supplement to the Brigham, Financial Management text chapter on Risk and Return Part 1.
