Building a Fund Portfolio · Closed End Funds
Several funds can own the same borrowers, sectors or economic risks. Counting fund names can therefore overstate diversification.
Look through the fund label
Two managers may hold many of the same bonds or stocks. Different names, distribution dates and share prices do not remove that overlap. Compare full holdings where available and use current dates. A top ten list helps identify concentration but cannot describe every shared position.
Calculate a common issuer exposure
Suppose 40% of a small fund sleeve is invested in Fund A, which holds 10% in one issuer. The other 60% is in Fund B, which holds 5% in that issuer. Before leverage adjustments, the combined issuer exposure is 7% of the sleeve: 40% times 10%, plus 60% times 5%. This is larger than either portfolio weight in isolation might suggest to a casual reader.
Map common risk factors too
Even without identical securities, funds may all depend on falling interest rates, strong credit markets or one regional economy. Several leveraged bond funds can suffer together when funding costs rise. Option income equity funds may all give up part of a strong market rally. Diversification involves economic drivers as well as security names.
Avoid concentrating the cash plan
If most household spending relies on several funds with similar distribution policies and exposures, payment cuts could occur together. Track the percentage of expected cash coming from each risk source, not only each fund. Stress a simultaneous decline in distributions and share prices.
A practical worksheet contains portfolio weight, major asset class, largest issuers, duration or equity sensitivity, leverage, currency and distribution sources. Record missing information rather than filling gaps with assumptions. Review after major portfolio changes or corporate actions.
Try it yourself
Half of a sleeve is in a fund with 20% utility exposure and half in a fund with 40%. What is the combined utility weight before leverage?
Show the worked answer
The combined weight is 30%. Equal allocation across two funds has not removed their shared utility exposure. Financing and derivative positions may change the effective exposure.
