2025 Portfolio Update: A 15.6% Return For The Full Year. CAGR of 13.2% Since 2021.
When I wrote my 2024 review last year , the CAGR was 12.7% across a 4-year period. The CAGR now stands at 13.2% across a 5-year period after a 15.6% return in 2025. I don’t think this result is too shabby but I was honestly expecting a better result at the end of Q3 2025. When Q3 was concluded, my YTD return was 21.3% and I was expecting that I could end 2025 with a >20% return. Unfortunately, Bitcoin has a different idea and dragged my portfolio down in Q4. The monthly retur

Your Career and Your Home Are Not Separate Decisions. They Shape Each Other More Than You Think.
We often talk about career planning and housing upgrades as if they sit in separate compartments. “Should I take this higher-paying job?” “Should we buy a $2M or $2.5M home?” Most people make these decisions in isolation- evaluating salary, commute time, mortgage affordability, or interior space.

2024 Portfolio Update: A 35.5% Return For The Full Year. CAGR of 12.7% Since 2021.
After 4 years of publishing my portfolio returns, I almost beat the market (S&P 500). The total return of my portfolio since January 2021 is 61.3%. The index has a return of 64% in the same period. The CAGR of my portfolio now currently stands at 12.7% after 4 full years. Not too shabby I guess but I still feel a little gutted to be lagging the market by a little. For those who have been following my blog, I constantly publish my portfolio updates over the past 4 years. In ca
