Historical view

This position has been exited. The thesis is kept as a record of the reasoning at the time and is not maintained as current research. See its decisions.

Investment case

Original thesis

IREN was held as power-linked digital infrastructure exposure, combining Bitcoin mining economics with an emerging AI cloud pivot. The thesis was that IREN's low-cost power base positioned it well to transition GPU capacity toward AI workloads as mining margins compressed.

What changed

The position appreciated significantly from the August 2025 entry. After a partial trim in April following a 127%+ gain, the remaining position was evaluated against other opportunities. The risk/reward at elevated prices relative to the AI pivot execution stage made reallocation the better portfolio construction decision.

Why the position was exited

Exited IREN fully on April 30 after the position had run up. The exit was a capital-allocation upgrade, reallocating away from a less attractive risk/reward setup toward better opportunities.

What it taught

Significant appreciation from a speculative entry creates a natural reassessment point. When a position has already captured most of the near-term thesis, holding requires a new and distinct reason to remain sized. Reallocating gains into higher-conviction setups is sound portfolio management.

    Exited after the AI/cloud pivot became a less attractive risk/reward at the new price. The position had already captured a large part of the original upside, so I preferred to recycle gains into higher-conviction opportunities.
