Python Financial performance comparison expert

Hi, all.

Here is the Jupyter Notebook I am working on.

I need your help from step 4 to last part.

In Step 4 it doesn't exclude all null values for some reasons.

I can't download S&P 500 from YF, ticker: ^GSPC. Also the Treasury ticker I cannot download: ^TNX

I am doing this for my studies and pay out of my own pocket.

Please keep the code as simple as possible and add detail comments as you can.

you have the mutual funds CSV source and files, you have my work in Excel where I did some computations, and you have the Jupiter notebook I was working on to consolidate the effort in all steps.

I think the Morningstar Ratings are also included in the Kaggle file - not sure if there is a difference.
