Best and worst investments of 2025
2025 was another great year to be an investor.
Chances are, you are pretty happy with your portfolio today. After a catastrophic 2022, the market rose over 20% in 2023 and 2024, and now 18% in 2025.
The S&P benchmark returned an average annual 10% from 1926 to 2024, and 74% of years were positive. The longer the time horizon, the higher the chance of positive returns. If you want to stack the deck in your favor, the easiest step by far is to trade less and ignore the doomsayers.
“Pessimists sound smart. Optimists make money.”
I share my stock portfolio with a community of long-term-focused investors. So I wanted to share the best and worst-performing investments this year:
📈 Best investment: AppLovin (APP): In March 2025, I wrote: “Several short reports have targeted the company, but they generally come from low-level analysts or content creators with no reputation or research teams. Conversely, hedge funds like Baillie Gifford, Coatue, and Sands Capital have invested in APP.” The market has been underestimating the leverage within AppLovin’s software platform. As the AI-driven AXON engine continues to optimize ad matching, we are seeing a decoupling of revenue growth from operational costs, leading to a massive repricing. The stock has nearly tripled since then, dramatically outperforming the market.
📉 Worst investment: The Trade Desk (TTD): I added to my existing position in February 2025, aiming to capitalize on what appeared to be a reasonable entry point. Since then, the stock has struggled with sentiment shifts in the ad-tech category and a slowdown in revenue growth, partially explained by tough comps from US political spending in 2024. The stock is down 50% from that specific purchase, making it our worst investment this year. TTD has also been the worst performer in the S&P 500. But consider this: TTD has been a holding since 2017, and despite the recent drawdown, the stock price remains over 10x our initial purchase price. It's another great reminder, if you needed one, that zooming out and keeping a long-term view is critical in investing.
You can expect How They Make Money to expand even more in 2026.
