Hey everyone,
In this latest Idea Streams episode we try to replicate an interesting chart of the Goldman Sachs non-profitable index. You can check out the video here and find out how well we did.
The backtest is attached below.
Happy coding!

Ollie Hooper,
Thank you for sharing.
Do you have a link to real methodology of "Goldman Sachs non-profitable technology index"?
In your code it defined as “50 unprofitable technology companies with the highest revenue”.

Hi Vladimir,
I believe they haven't disclosed the methodology behind the index. I think I saw something suggesting it was qualitatively created as well. There is a picture of the current constituents off a bb terminal here.

Hello Ollie
I noticed that the strategy seemed to have holding of 200% of equity at certain points of the backtest. So I added a OnSecuritiesChanged() method inorder to take out the stocks that had fallen off or added new to the universe. Am I applying it correctly? I'm fairly new to QC and I'm trying to get a hang of it.
Thanks :) keep up the coding vids they're really helpful
