Count the sources of exposure, not just the lines on a portfolio statement.
Look for shared dependencies
Imagine several investments whose success all relies on the same industry, customer group, or funding environment. Their names may differ while their underlying assumptions overlap. A dependency map makes these connections easier to discuss.
Use a holdings worksheet
Place investments in rows and underlying exposures in columns. Mark where a company, sector, or region appears more than once. Use fund holdings documents with clearly recorded dates; a worksheet built from incompatible periods can be misleading.
Question the apparent gaps
An empty cell can mean that an exposure is absent, but it can also mean the available information is incomplete. Mark unknowns separately. The aim is a useful representation of what is known, not a visually balanced table.
Know the limitation
Diversification can reduce concentration, but it cannot guarantee a profit or prevent market losses. A completed worksheet should therefore include risks that remain shared across the portfolio and questions that need further investigation.
