Suggested foundations for portfolio construction and probability and statistical reasoning. Specialist prerequisites vary by paper.
Understand the covariance structure of portfolio risk.
Read objectives, constraints and optimality conditions.
Read the distributions and expectations used in probabilistic arguments.
Interpret expectations after information is observed.
Construct allocations and examine sensitivity to estimated inputs.
Turn mathematical weights into feasible portfolio decisions.
Assess uncertainty rather than treating an estimate as a fact.
Connect diversification, common risk factors, investor views, and the properties of a risk measure.
Move from conditioning and expected values to timed problems with a defensible solution.
