This 15 (approx) minute video showcases my portfolio optimizer which I have shown before. Do realize this can be applied to any asset class. You can always search on my Youtube channel for 'portfolio' as hinted in this video. The idea here is to showcase you could triple your expected return by using the appropriate strategy type with proper optimally weighted positions. This is all shown in the video. I would say this is one of the biggest reasons to automate your strategy and trading. No human can do this if you were to allocate a higher number of positions across multiple asset classes for the day. You could even run this script every few hours if I wanted to allocate positions every X hours. I would have to feel pretty lucky to do that.
