1. 033Your analysts give you return forecasts with wildly different levels of confidence. How do you build the portfolio?Portfolio constructionHardcase studyMulti-assetFundamental asset management

   Say this

   Make the confidence an input rather than a footnote. Convert each forecast into a signal with a dispersion attached, scale positions by the ratio of the expected return to its uncertainty, and let low-confidence views sit near benchmark weight instead of arguing them down qualitatively.

   Then walk it

   1. First, standardise the forecasts so they are comparable. Analysts express things differently, so I would convert everything to expected excess return over the same horizon, then to a z-score within the coverage universe.
   2. Then attach dispersion. Ask each analyst for a bear and bull case, not just a target, and use the spread as the uncertainty estimate. Position size then scales with expected return divided by variance, which is the Black-Litterman intuition applied at the stock level.
   3. Then adjust for track record rather than confidence expressed. Confidence and accuracy are barely correlated, and the analyst who sounds most certain is often the most overfitted. If I have hit rate data by analyst and by sector, I would shrink each forecast toward zero in proportion to their historical noise.
   4. Then handle correlation between views. Five high-conviction calls that all require the same rate path are one position. I would run the proposed portfolio through a factor model before trading, and cut the aggregate exposure rather than any single name.
   5. Then cap the damage. A hard maximum active weight regardless of stated conviction, because the largest single loss in a fundamental book usually comes from the position everyone agreed about.
   6. The organisational part matters too: if analysts learn that stated confidence drives sizing, confidence inflates. So the sizing rule should use the bear case and the historical accuracy, which are harder to game than a stated conviction score.

   Where candidates lose it

   Answering 'size by conviction' without saying how conviction becomes a number, or ignoring that stated confidence is gameable and uncorrelated with accuracy. The strong answer uses the bear case as the uncertainty measure, shrinks by track record, and aggregates the views through a factor model before trading.

   Expect next

   • How would you measure an analyst's hit rate?
   • What if the highest conviction ideas are all correlated?
   • Would you ever override the sizing rule?
