Joseph, thanks for reading and commenting. Of course the S&P 500 is the gold standard and the default benchmark. I use it to compare all my investments because if I didn't invest actively or in real estate, my money would be in the S&P 500. So it wasn't an intentional omission, just the most widely-used benchmark.

That being said, I did go through an analysis of the NASDAQ and updated the story with the results. The Russell 2000 performed very similar to the S&P 500, so I didn't include it. NASDAQ has had a major boom since 2020, beating both Berkshire and the S&P 500 by a wide margin over certain periods. But as you will see in the data, BRK-A is back on top for YTD and 1 year returns in addition to outperforming that index by huge margins over long periods of time.

I provided the link to the chart in my article, so you can go through any additional analysis yourself if you so choose. There are an infinate number of ways to slice and dice something, so there is only so much that makes sense to include in an article.
