Missing video in the 'Python for Finance' course ?

I recently completed one of my favourite modules inside your course. The "Python for Finance" module.
But I was wondering whether there is a missing piece of content in the section "Capital Asset Pricing Model".
At the end of the video "Measuring Alpha and Verifying How Good (or Bad) a Portfolio Manager Is Doing" the speaker mentions the next lesson and the analysis and calculation of alpha but the next video is under a new section "Multivariate Regression Analysis". Maybe I am missing something there but I could not find the video about calculating alpha and using it for performance analysis (you see I am very keen on this topic :) Could it be that this video is missing? Thank you very much for your time and reply   P.S.: Could not find the appropriate category "Python for Finance" in the Q&A HUB as I was posting this question.
