Core tracked portfolio – £17,751(+£2,887)+18.54%

These numbers come straight from the dashboard and form the new baseline for future monthly comparisons.

The portfolio had a very strong month, delivering +18.54% growth and pushing the core tracked balance to £17,751 (71% of the £25k breakout target).

SpaceX IPO success: On 3 June I reserved £2,000 for the SpaceX IPO on eToro. The allocation was filled on 12 June with 19 shares at $135 each (~$2,565 total). The shares performed exceptionally well, soaring nearly 46% from the IPO price at one point (reaching ~$3,740 mid-month with over +£1,180 unrealised gain). The position closed the month at $3,002.00, up +17.04% overall since allocation.

Major SpaceX developments: Mid-month SpaceX announced a $60 billion all-stock acquisition of AI coding startup Cursor. On 22 June, the company signed a major computing power deal with Nvidia-backed open-source AI startup Reflection AI — worth up to $6.3 billion, with Reflection paying ~$150M per month starting July for access to GB300 chips at the Colossus 2 data centre.

Market volatility: Early in the month (5 June) there was a sharp market dip that took the portfolio down to £14,010 temporarily, but it recovered strongly.

Steady income & admin: Received dividend payments from InvestEngine and voted on NVIDIA shareholder documentation.

Biggest takeaway: The successful entry into SpaceX has been a standout performer and added meaningful diversification to the growth assets. Combined with the continued strength of Tesla, NVIDIA, and the custom pies, the strategy is showing good momentum while the stable income experiments continue to deliver reliable, low-volatility returns.

We’re now past the £10k “Stable orbit” milestone and sitting at 71% 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.
