About Eric Rutanga

Clinical Pharmacist & Private Investor. Applying medical rigour to capital allocation.

I am a Pharmacist with experience in the UK healthcare system, and a private investor focused on high-quality compounding businesses.

The standard financial advice is simple: "Buy the entire market and go to sleep."

For 99% of investors, broad, low-cost index funds are the right choice. They protect you from not knowing enough.

But "Average" is not a strategy; it is a safety net.

I believe that if you have a real advantage in a specific sector, you should use it. I do not try to beat the market by guessing where the economy is going. I aim to do better by applying clinical rigour to the one sector I understand better than the average City analyst.

My Edge: The Clinical Lens

I don't look at healthcare from a spreadsheet; I understand what happens on the hospital floor.

  • The Disconnect: The market sees a sales forecast and a new drug pipeline. I see the reality: Will the NHS actually pay for it? Will doctors actually prescribe it? Will patients actually take it?
  • The Mechanism: I know the difference between a true medical breakthrough and a small tweak just designed to keep a patent alive.

This is my Circle of Competence. Outside of this circle, I am cautious. Inside it, I am aggressive.

My Philosophy: The "Consultant" Approach

In medicine, we do not guess; we look for evidence. I apply the same rule to my money.

1. Diagnosis (Price) Is the company too expensive, or is there a verifiable margin of safety?

2. Prognosis (Strength) Does this business have a competitive immune system (moat) strong enough to keep it winning for 10 years?

3. Treatment (Buying) I buy a few high-quality companies. I do not hold 50 stocks just to feel safe. I hold the few I know are healthy.

What You Will Find Here

  • No Hype: I do not chase penny stocks, crypto, or unproven fads.
  • Institutional Data: Analysis based on primary sources (Clinical Trials, S&P Global data, Regulatory Filings), not internet rumours.
  • Clear Thinking: A journal of why I buy, why I sell, and—crucially—where I have been wrong.

This is not a signal service. It is a look over the shoulder of a clinician applying a professional standard to investing.
