1. 024Which sector would you overweight today, and what would you fund it from?Asset allocationIntermediatetechnicalWMWellington ManagementGeneralist · Hong Kong · 2022

   Say this

   The 'funded from' half is the real question. A sector view is only a portfolio decision once you have said what it displaces, and the pair determines what risk you have actually taken, because an overweight funded from cash is a beta increase and one funded from a correlated sector is a relative value trade.

   Then walk it

   1. Pick a sector where you can state the mechanism in one sentence, name the two or three numbers, and say what the market is assuming that you think is wrong. Specificity beats breadth here.
   2. Then be explicit about the funding leg. Funding an overweight from cash adds market beta. Funding it from a defensive sector adds beta and cyclicality. Funding it from a sector with the same driver, say industrials out of materials, isolates the idiosyncratic view, which is usually what you intend.
   3. Check what else comes with it. Sector bets carry factor exposures whether you want them or not: financials are a rate and curve bet, staples are duration, technology is long growth and long the multiple. Say which factor you are unintentionally buying.
   4. Size it against a tracking error budget. A 3 point sector overweight in a portfolio with a 3 percent tracking error budget is a substantial use of that budget, and I would say how much of the budget I am spending.
   5. Give the falsifier and horizon: the data point that would tell me I am wrong, and when I would review. Sector rotations often need two to three quarters to work, so a one month judgement is noise.
   6. And I would be honest that sector allocation has a weaker evidence base than stock selection within sectors, so I would keep the tilt modest unless the mispricing is unusually clear.

   Where candidates lose it

   Giving a sector view and never saying what you sell. Interviewers in allocation seats are specifically listening for the funding leg and for the factor exposure that comes attached. Naming the unintended factor bet, rates in financials or duration in staples, is what makes it sound like a real portfolio decision.

   Expect next

   • What factor exposure does that pair give you?
   • How much of your tracking error budget does it use?
   • What would make you close it?

   Say this

   Lead with the recommendation, the variant view and the number, then the sizing. In a portfolio seat the sizing is half the question, so say what it displaces, what the bear case costs you, and how much of the risk budget it uses.

   Then walk it

   1. Thirty seconds of thesis: what it is, what the market believes, what you believe instead, and why that gap exists. Then the target and the path, with one or two numbers you can defend, not a full model walk-through.
   2. Then the falsifier, unprompted. 'I am wrong if gross margin does not reach X by the second half, and that is testable in two quarters.' A thesis with a date and a number is a professional thesis.
   3. Then the bear case quantified, because it drives the sizing. If the downside is minus 35 percent and I am willing to risk 1.5 percent of the fund on any single name, the position caps at roughly 4 percent.
   4. Then the portfolio fit, which is what makes this a portfolio management answer rather than a stock pitch. What factor and sector exposure does it add, what does it duplicate in the existing book, and what am I selling to fund it.
   5. Then liquidity and capacity: days of average volume for the intended position, and how long an exit would take in a stressed market. For anything mid or small cap that constraint can bind before conviction does.
   6. Then be ready to defend it under pressure, because the standard follow-up is 'are you sure the thesis can be backed up?'. The right response is to name the two or three facts the thesis depends on, say how you verified each, and concede the one you are least sure about. Defending everything equally is what gets candidates marked down.

   Where candidates lose it

   Delivering a stock pitch and never mentioning size, funding, correlation or liquidity. This question is asked in a portfolio seat, so the construction half is the differentiator. And when they push back, do not defend every point with the same conviction; identify your weakest assumption before they do.

   Expect next

   • Are you sure that thesis can be backed up? What if costs do not fall?
   • What would you sell to fund it?
   • How long would it take you to exit?
