1. 065How would you allocate a $100 million mandate across a portfolio of funds?Portfolio and riskHardsuperdayMSCIRisk Management · Remote · 2013The Vanguard GroupInvestment Research · Malvern · 2024

   Say this

   Start from the objective and the constraints, not from the funds. Required return, risk tolerance, liquidity needs, time horizon and any restrictions. Then build the strategic asset allocation, then select managers within it.

   Then walk it

   1. Establish the mandate first: what return is required, over what horizon, with what drawdown tolerance, what liquidity is needed and what restrictions apply. Everything follows from these.
   2. Set the strategic asset allocation across asset classes. That decision drives the large majority of the variance in outcomes; manager selection is second-order.
   3. Then decide active versus passive by asset class. Use passive where markets are efficient and active where dispersion is high and there is evidence of persistent skill.
   4. Then select managers on process rather than past returns. Understand the source of the edge, whether the team is stable, whether assets have grown beyond the capacity of the strategy, and what the fee structure does to net returns.
   5. Then look at the combination rather than each fund alone. Correlation between managers is what determines portfolio risk, and three managers running the same factor exposure is one position with three fee loads.
   6. Then build in the governance: rebalancing rules, review triggers, and a plan for what would cause redemption. Deciding the sell criteria in advance is what prevents performance-chasing.

   Where candidates lose it

   Jumping straight to picking funds. The correct structure is objectives, then asset allocation, then managers, then monitoring. Also, ignoring correlation between managers, which is the most common real-world error in multi-manager portfolios.

2. 067What is tracking error and how do you calculate it?Portfolio and riskIntermediatetechnicalMSCIFinancial Tools · Monterrey · 2013

   Say this

   The standard deviation of the difference between the portfolio's returns and the benchmark's. It measures how far a portfolio can drift from its index, and it is the budget within which an active manager operates.

   Then walk it

   1. Calculate the active return each period, portfolio minus benchmark, then take the standard deviation of that series, usually annualised.
   2. Ex-post tracking error uses realised returns. Ex-ante uses a risk model to forecast it from current holdings, which is what a risk system reports daily.
   3. Typical levels: an index fund runs a few basis points, an enhanced index strategy 1 to 2 percent, an active manager 4 to 8 percent, and a concentrated high-conviction fund can be well above that.
   4. It connects to the information ratio, which is active return divided by tracking error. That ratio, not raw outperformance, is how skill per unit of risk is judged.
   5. The main use is as a constraint: a mandate sets a tracking error budget, and the manager allocates it to the positions with the highest expected information ratio.
   6. The subtlety worth naming: tracking error is symmetric, so it penalises outperformance as well as underperformance. A manager can have excellent returns and breach a tracking error limit, which is why the constraint sometimes forces suboptimal decisions.

   Where candidates lose it

   Confusing it with volatility. Tracking error is the volatility of the difference, not of the portfolio. A low-volatility portfolio can have very high tracking error against a volatile index.

   Expect next

   • What is the information ratio?
   • What tracking error would you expect from a concentrated fund?
   • How does a tracking error budget change portfolio construction?
