Risk Management interview preparation
Market, credit and operational risk, plus model validation, regulatory capital, liquidity and ALM, the statistical foundations and the Indian regulatory syllabus. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it — and answers lead with the point, then the mechanism, then the limitation.

070What's the tracking error formula?MSCIFinancial Tools · Monterrey · 2013
Say this
Tracking error is the standard deviation of the difference between portfolio and benchmark returns. Compute active return each period, take its standard deviation, then annualise by multiplying by the square root of the number of periods in a year.
Then walk it
- Formula in words: active return equals portfolio return minus benchmark return each period. Tracking error is the standard deviation of that series. On monthly data you annualise by root twelve, on daily by root 252.
- The ex-post version uses realised returns. The ex-ante version uses a risk model: active weights transposed times the covariance matrix times active weights, then square root. Those two numbers routinely disagree, and explaining the gap is a real part of a buy-side risk job.
- Be careful about mean adjustment. Some definitions use the standard deviation of active returns and others use the root mean square of active returns, which includes the average outperformance. They differ, and you should say which one you mean.
- Feel for the numbers: an index fund runs 5 to 50 basis points, an enhanced index strategy 0.5 to 2 percent, an active core equity fund 3 to 6 percent, and a concentrated high-conviction fund 8 percent or more. Quoting a range is what shows you've looked at real funds.
- What it's used for: mandate limits, since most institutional mandates cap tracking error. And the information ratio, active return divided by tracking error, which is the risk-adjusted measure of skill and the number that actually matters.
- Decomposition is the useful part. Break tracking error into factor and specific contributions: how much comes from a systematic style or sector tilt versus stock selection. A manager paid for stock picking who is running most of their tracking error on an unintended country bet has a problem, and that's exactly the conversation a risk analyst has with a PM.
- Limitations to volunteer: it's symmetric, so it penalises outperformance identically to underperformance. It assumes a stable covariance structure, so realised tracking error jumps in a crisis. And it's backward-looking, so a manager who has just changed their positioning has a stale number.
Where candidates lose it
Giving the formula and nothing else. This question is a screen: the formula takes five seconds, and the rest of your answer is what's being assessed. Knowing typical ranges by strategy, the ex-ante versus ex-post gap, and factor decomposition is what converts a definition into an answer.
