You can skip all of these lessons and head straight to this Google sheet file, which allows you to reach the portfolio correlation step, which is a step after this one, right away. All you need to do is fill in the ticker name for the stocks that you have and its weight. All credit for the sheet file goes to John Mihalik who published it on his Medium page.
