How a portfolio fits together, before choosing what goes in it.
Portfolio School is a small, independent resource based in Switzerland. We explain the general concepts behind building a portfolio — allocation, diversification, rebalancing — no products, no stock picks, no personal advice, no cost.
Three ideas behind how a portfolio fits together.
Allocation is a structural choice
How money is divided across asset types tends to shape overall outcomes more than the choice of any single holding.
Diversification manages, not eliminates, risk
Spreading exposure reduces the impact of any single holding going wrong. It doesn't remove risk from the portfolio entirely.
Rebalancing keeps intent aligned with reality
As holdings grow at different rates, an allocation drifts. Rebalancing is the general process of realigning it with the original plan.
Structure first, individual choices second.
Most investing content jumps straight to which specific holdings to buy, skipping the structural questions that usually matter more. Portfolio School was built by a small group of finance writers who wanted to slow that down — explain how a portfolio fits together as a whole before any individual choice gets made.
