Who is behind this
I am Preisha Rao, a final-year Finance and Economics student at Flame University. I built this archive to keep track of my model portfolio.
Why this exists
THE QUESTIONI had been researching companies and tracking a portfolio for a while, and I could tell you what I owned and how it had done. Then I tried to reconstruct why I had rated a company the way I had six months earlier, and found I could not. The reasoning had been real at the time, but it lived in my head and in scattered notes, and it was gone.
That is a problem, because the first question any interviewer asks is not what you bought. It is how you arrived at that view. A score nobody else can reproduce is an opinion with a number painted on it, and I had a portfolio full of them.
So I rebuilt the whole thing around a single rule: I write down the thresholds first, then record the evidence, and the score is computed rather than chosen. Everything gets published with a date and is never edited afterwards. If you want to check any number on this site, you can.
Not returns. Eighteen months of a paper portfolio says almost nothing about skill, and I say so on every performance table. What this site demonstrates is a repeatable process, applied consistently, published honestly, and open to being taken apart.
How I work
FOUR COMMITMENTSRules before companies
Every threshold was fixed before I researched anything, and applies to every company identically. Changing one means re-scoring everything, openly. That is the cost that keeps it honest.
Evidence in, score out
I do not type a score. I record the figures and the rulebook grades them. Where judgement is unavoidable, on the moat, the runway, momentum and governance, it is marked as judgement wherever it appears.
Governance is a gate
Five questions run before any score matters, and a single red flag ends the analysis regardless of how good the numbers look. The businesses that destroy capital permanently rarely have mediocre ratios.
Publish, then leave it alone
Sell triggers go up before they fire. Scores are frozen with the rulebook that produced them. Corrections are new dated entries. The archive is only worth anything if it cannot be quietly revised.
If you have four minutes
WHERE TO LOOKThe rulebook →
Every threshold, fixed in advance. This is what makes the scores checkable rather than assertable.
One holding in full →
Every input, the threshold it met, and the quarter a verdict changed without me deciding anything.
Allocation and drift →
The product with no scores, judged instead on whether I held the bands when it was uncomfortable.
What I would want you to ask me
FAIR GAME“How did you get that score?”
“Where does your model break?”
“Tell me about a mistake.”
“Have you beaten the market?”
What I am not claiming
THE LIMITSIt seems fairer to state these than to let you find them.
| Track record | Eighteen months, on paper, with no client money and no fees. A short record in a single market cycle. |
|---|---|
| Sample size | A small number of companies researched in depth, rather than broad coverage. |
| Market conditions | I have not managed a portfolio through a severe drawdown. My sell triggers have not been tested by one. |
| Credentials | Not a registered investment adviser or research analyst. This is educational work. |
| The model itself | A way of organising judgement, not a measure of truth. Several inputs are explicitly my own judgement. |
