1. 013A manager has beaten the index for five years, but the returns load heavily on momentum. What do you do?Factor modelsHardcase studyMulti-manager allocationFund selection

   Say this

   You do not fire them for having a factor tilt, you reprice them. If the excess return is momentum beta, you can buy that exposure for maybe 25 basis points, so the question becomes what is left after the factor and whether the fee is justified by that residual.

   Then walk it

   1. Quantify it first. Run the fund on market, size, value, momentum and quality, and split the excess return into factor contribution and intercept. If 80 percent of the 3 percent excess is momentum loading, the true alpha is 60 basis points before fees.
   2. Compare that to the replication cost. A momentum ETF or a swap on the factor costs a fraction of an active fee. If the manager charges 90 basis points for 60 of residual, the client is paying for beta that is available cheaply.
   3. Then ask whether the loading is intentional. A manager who says 'we buy businesses with improving fundamentals and yes, that looks like momentum' is coherent. One who claims pure bottom-up stock picking while the regression says otherwise has a process-outcome mismatch, which is the actual red flag.
   4. Then check the portfolio context. If I already hold two momentum-heavy managers, this one is redundant regardless of its standalone quality. Correlation of active returns across managers is what determines whether the roster adds anything.
   5. Then the risk question. Momentum has periodic violent crashes, 2009 being the classic, so a portfolio unknowingly stacked on it has a fat left tail that will not appear in the trailing five year statistics.
   6. My action: renegotiate the fee or the mandate, hedge the factor centrally if I want the residual, and if neither is possible, replace the position with the cheap factor and spend the saved fee budget on a manager whose alpha is not replicable.

   Where candidates lose it

   Answering either 'great track record, allocate' or 'it is just factor beta, fire them'. Neither is a decision. The professional answer prices the replicable part, tests whether the exposure is intentional, and checks redundancy against the existing roster.

   Expect next

   • How would you hedge the momentum exposure?
   • What if the manager says momentum is their stated process?
   • How long a record would you need to be confident in the residual?
