Tracking performance is essential to improving your process and I've done that since my earliest investing days, but what I have not been able to do as well is determine an appropriate benchmark. I use the SP500 by default, even though my portfolio looks nothing like it, because it represents the most accepted measure of "the market" at least for a US investor. I don't use a small cap index for comparison because I would never personally buy those indexes since they include so many junky companies that have proven themselves unable to get promoted to a larger cap index.

In 2024, I just missed outperforming the SP500, but I did so without ever owning Nvidia and Netflix (and a sincere congratulations to those of you who have owned those two for 10 years!) Does that mean I had a bad year or a good year in 2024? I think its too soon to tell. If Nvida has a 13 trillion market cap in 6 years, it will mean that every year I didn't own Nvidia was a bad one but if it stalls out at 5-6T, well then maybe I'm doing something right. We'll see.

Great post. Similar thoughts on sharing returns. To me it makes sense if you're running a newsletter or partaking in the community, but sharing quarterly performance is about as useful as daily performance. I want to know 2 things: that time-weighted return since inception on a daily basis, and your "stress/return ratio": https://fundooprofessor.com/2012/04/05/returns-per-unit-of-stress/

Good points on health, acknowledging different stages of wealth management (contributing, protecting, steadily withdrawing, etc).

These types of posts are great IMO

EDIT: I'm super proud of my learning, having achieved a ~21% CAGR since inception (time-weighted) with a return/stress ratio of 9.9 out of 10. I prioritize my health and relationships over work, and I'm almost 100% sure that there's no better way to live.

ANOTHER EDIT: Third thing I'd love to know from investors is how much they think is luck vs skill in their returns. For me, I know it's more luck than anything, but luck counts in this business (and it's more dangerous to disregard luck).
