I know a bit about this industry and I have worked on some profitable systems. Honestly not a bad effort for someone working on their own with low-cost data. Don’t let the haters get you down. I would recommend you to pick up a more recent textbook on portfolio construction like Isichenko’s recent book.

Thank you for the note! Just picked up Isichenko from the online bookstore we all love-hate.

I'd love to get in touch (as per your HN profile) - my email is am(at)principiamundi.com
