FOUNDATION — Your first portfolio

The Logifin guide to the foundations: how you design your allocation, how you choose the core, how you avoid the traps and how you build a portfolio that holds up in every market.

Plan & Grow · 22 min read · 2026 edition

A guide for Logifin Circle members. The introduction is free, the full guide with a membership.

In the COMPASS guide you learned why you invest, with which tools and with which system. One question was left open, the most personal one of the journey: what does your own portfolio look like? How much in stocks, how much in bonds, which indices, in what proportion? And how do all these pieces form a whole that will hold up in the hard periods too?

This guide is the foundations. It will not hand you "the perfect portfolio", because no such thing exists. A portfolio is not a product; it is a decision fitted to one specific person: you. It will give you something better: the method to design, on your own, a structure that is simple, cheap and resilient, so that you understand at every step what you are doing and why.

As always at Logifin: no unexplained jargon, no magic formulas and a European view throughout.
