Ysdrasill's 2025 Year-In-Review

Hi everyone,

Below is, as I do each year, the yearly update since I started investing (and found this board at the same time) in November 2020.

First a quick personal update - I am now closing my first year as a business owner, and things are going reasonably well, it the sense that we are still going, and started to hire a bit more. It’s also very stressful and I fail at something literally everyday. Yet, I feel so blessed that I get to continue to learn surrounded by mighty smart people, including on this board.

Now for the investing: I choose to compare at both NDX (100) and SPX. For reference, in 2020 I invested for about 6 weeks as a beginner.
I also updated all my calculation to use time weighted.

As you can see, I closed 2025 at 60.5%, which isn’t bad.

Here is my portfolio as of today- I plan to make some changes in the days to come after taking some time to review each company.

All in all, it’s been another good year for me. I am now positive, even after the debacle of 2022, and with a 6% 5Y CAGR since I started end of 2020.

While I am happy, this is actually objectively quite bad: this is underperforming any of the indices I follow on the same period, meaning I would have earned more money by investing in them. And this isn’t accounting for the time i spent picking stocks, of course.

This is important for me to highlight, as I don’t want newcomers to think this is in any way a magic wand. Even the best investors on this board, if they take the past 5 years, will almost all underperform simple indexes.

The power of this approach resides in the long term, and we should collectively get much better at managing drawdowns. I still remember even Saul feeling absolutly terrible during 2022. This isn’t a subject for today, but if you’re starting to invest, please consider having a plan to mitigate losses in mind.

However - and outside of that - I have learned a great deal, and I am starting to be confident that I can beat the market consistently, and that is an awesome feeling!

As for past goals and learnings - I also wrote last year:

"My goals for 2025:

  • Beat the Nasdaq for a second time, proving this is not a fluke year
  • Further progress on my entry/exit timing and solidify my own thesis around stocks
  • If finance permit, slowly start adding some funds again - I would like to wait to have gotten back to my initial investment "

I have achieved each of these goals, and started re-learning a bit about options. I actually made some money overall, that would add about 5% to my early returns, but I want to focus on stocks only in these recaps.

Unsurprinsigly, I again made many, many costly mistakes. After entering both NBIS and IREN at great prices, I bought more late on the way up, shattering a good part of my gains.

Last year, I also wrote:
"I still hold today TMDX and ASPN, when in hindsight it is evident I should have sold both and re-allocated at the first sign of weakness. I am now holding them because I believe they are at extremely depressed valuation, but I might be entirely wrong. "

ASPN turned out to be a big mistake, and I sold it rapidly after year start. I still hold TMDX in size, however I have trimmed it often near its highs as I understand the stock much better.

My plan remains to continue investing mostly in domains I understand very well, notably in AI and tech, as well as ecommerce.

I am ever so thankful for the contributions of this board, and I am looking forward to this new year. I believe it will bring a new set of challenges, many that scare me for reasons that have nothing to do with money.

However, as I concluded last year: where there is change, there is opportunity :slight_smile:

My best wishes to you all!

@Ysdrasill Thank you so much for the very thoughtful post. You have had back to back 60%+ years and a 40% year before that, which would make a lot of people jealous. But you’re right, 2022 was a nightmare. When you’re down 2/3 of your starting portfolio, when you go from 100 to 33, you need a 200% gain to get back to even. Sobering math.

But your take away is correct too. It’s not that owning a concentrated growth stock portfolio is sub-optimal. It’s that it’s extra-volatile. And it’s so important to know the game you’re playing.

Many prefer to play the game the way Saul always did – staying 100% invested at all times, and concentrating into your best ideas. I play it a little differently, adding and trimming constantly, holding some cash, and concentrating only when I think there’s something worth concentrating into.

Others play the game by simply buying S&P500 index funds every time they get paid. They also do fine, and depending on how early they start and what percentage of their paycheck they put into the market, they can often enjoy an early retirement too.

Thanks for highlighting this, and to me it seems you’re on the right track and highly aware of the game you’ve chosen.

Many happy returns to everyone in 2026!
