Putting it together
Allocation, real versus apparent diversification, correlations that change when you need them most, and when rebalancing is worth doing.
A portfolio is not a list of good ideas. It is a structure.
These notes cover how the pieces fit: how much of each, why holding more funds is not the same as being diversified, why assets that moved independently for years can stop doing so at once, and what to do when the weights drift.
