Monthly Report – April 2026: £13,681 Portfolio + All Experiments Breakdown
Welcome to the very first Mars Money Lab Monthly Report! This April 2026 monthly report covers the full portfolio performance and all experiments.
Another month in the lab, and as of the 1 May 2026 market close, the core tracked portfolio stands at £13,681 — up a solid +7.9% over the past month.
Starting with this edition, I’m moving to a single monthly report that brings together every active experiment in one clear, comprehensive update. Each month you’ll get a full overview of last month’s performance across the entire portfolio, month-over-month comparisons, the latest numbers from every experiment, key lessons learned, and a progress check on the roadmap to £25k (and beyond).
This new format makes it much easier to see the big picture, track how the overall strategy is performing, and follow the journey in one place. Let’s dive in.

Key Insights & Lessons from April
The portfolio had a strong month overall (+7.9%), driven mainly by the tech holdings — Tesla and NVIDIA both performed well.
NVIDIA had a strong month on continued AI demand and positive market sentiment around its dominance in the sector. Tesla had a more volatile bearish run mid-month (likely due to broader EV market pressure and news flow) but still ended the month positive thanks to its long-term growth narrative.
Matched Betting and ETF Dividends continue to deliver steady, reliable profit with almost zero volatility. Crypto (BTC + ETH) was more muted this month but still positive.
Biggest takeaway: diversification across cashback, matched betting, dividends, and growth assets is working exactly as planned.
Roadmap & What’s Next
We’re now past the £10k “Stable orbit” milestone and sitting at 54.7% of the £25k breakout target. Next focus remains the same: consistent DCA into the growth assets, maximising cashback/profit from the low-volatility experiments, and keeping the dashboard updated daily.
