Five minds. One portfolio. Zero noise.
Five minds
A portfolio
Zero noise
Ask in plain language. Elisa puts it in circulation across the team and Cerebro answers with sources, limits and cost. And it gives a verdict, not an «it depends».
History of this desk
Elisa is an artificial intelligence, not a person. Her answers are generated by an AI model.
This is general analysis and not a personalised investment recommendation. The person who invests is the one who decides. The chat may search the internet when the vault does not know the answer (a figure from today, a recent news item); those internet sources nobody has reviewed them and they may be incomplete or wrong, so check them before acting. The five profiles that sign the answers (Elisa, Jorne, Carlos Bárez, Daniel Ferrer, Inés Torres) are specialisms of one single automatic system: they are not people nor registered advisers.
Tools
Note down your positions and watch how they do. Without an account they are stored only in this browser; with an account, they sync across devices.
What leaves your browser
When you ask in the chat, the text of the question and the history of that conversation are sent. If you have saved reading preferences, the vocabulary level and the depth are sent too. Your saved positions they are not attached to the chat; the portfolio and the scenarios use them in their own sections. That is why answers are general and not personalised: Cerebro is not financial advice. Avoid writing personal or financial data that is not needed. The securities search sends the search text and price queries send the symbols. See the privacy policy to find out which providers there are and what else is used.With your session signed in, positions are are stored in your account: they sync across devices and are deleted with the account. Type the name or the ticker and pick from the list so we know exactly which security it is and which exchange it trades on.
Load portfolio from text
One position per line: TICKER [shares] [price]. The comma works as a decimal point. Repeating a ticker updates it.
Your portfolio starts with one position. Add a security at the top and, if you want, the shares and the entry price.
Scenarios
Two hypothetical accounts with the assumptions you set. They do not predict the market nor rely on your portfolio: they show what what you type implies. If a figure is missing, the screen says: n/a and why. Never a zero that can be read as data.
Search by title or subject; not inside the notes.
Model portfolios · Example
100 % equities
All of the capital in developed-market equities, with no bonds, gold or cash. Here it serves as a benchmark: the rest of the portfolios in this section are easier to understand when compared with this one, the portfolio that cushions nothing.
The idea
Keep the return of the equity market, with all of its drawdowns, and add nothing to offset it. It is the simplest allocation to maintain: a single sleeve, nothing to rebalance.
The price of that simplicity is that the portfolio's drawdown is the market's drawdown, in full.
Where it comes from
It has no author: it is what you get when you invest all of your capital in a global equity index fund.
Environments in which it struggles
- In a long stock market decline: there is no sleeve that slows the fall.
- With sharp rises in interest rates: companies' future earnings are worth less today and valuations fall.
- When the money is needed on a specific date: a sharp fall may coincide with the moment you have to sell.

Los instrumentos son de referencia para cada índice, no una selección de producto: dicen qué fondo sigue cada índice, y la tabla no es una lista de compras.
Cómo se ha calculado y de dónde salen los datos
Rentabilidades pasadas no garantizan rentabilidades futuras.
Simulación con índices reconstruidos a partir de datos públicos (BCE, Banco Mundial, Kenneth R. French); no es la rentabilidad de ningún fondo ni ETF. Sin comisiones, impuestos ni costes de cambio.
Rebalanceo anual al cierre de diciembre, rentabilidad total y divisa euro. Cada mes, cada tramo crece con el índice del suyo; al cierre de cada diciembre la cartera vuelve a los pesos de la ficha. La ventana va de sep-2004 – ago-2026, 22 años de rentabilidad, y todo está en euros, convertidos con el tipo de cambio de fin de mes del BCE. Los índices de renta variable y de deuda son de rentabilidad total; el del oro es el precio del metal y el de materias primas es un índice spot, así que no incluyen ni el roll ni la rentabilidad del colateral de los futuros.

Adjust how we explain it to you
Two optional questions: your vocabulary level and your preferred depth. They are used to adapt the explanation. We do not ask about amounts of money and we do not run a suitability assessment. The answers are generated by the system and may contain errors; these preferences do not guarantee that the result is identical in every case.
