There is no one single correct way to structure a portfolio! As long as you are consistently investing and/or pursuing a reliable trading strategy, then you are on the right track.

I believe that everyone should be investing in an index fund regardless of their favorite trading style even if that index fund only makes up 10% of their portfolio because the simple math of long term capital gains is insane.

As you will learn in this video, I have roughly 70% of my money in long term index funds and the 30% in short term swing trading. This way I can capitalize on the long term passive returns while having money to capitalize on short term fluctuations and stock market crashes.
