What is Concentration Risk?
The risk that returns are dominated by a single asset, sector, geography, or borrower — magnifying both upside and downside.
Concentration risk is the risk of disproportionate exposure to a single investment, sector, geography, or counterparty. The opposite of diversification, concentration magnifies both upside and downside outcomes.
Forms of concentration risk in NZ wholesale investing: - Single-asset concentration — a property syndicate exposed to one building; a direct-investment LP exposed to one company. - Sector concentration — a fund overweight property development in a single sub-market (e.g. Auckland CBD office), exposed to that sub-market's cycle. - Geographic concentration — most NZ wholesale credit funds are explicitly Auckland + main centres focused; weakness in those markets affects fund returns disproportionately. - Borrower concentration — a credit fund where 30%+ of loans are to a single borrower or borrower-group has individualised default exposure. - Manager concentration — an LP's entire alternatives portfolio with a single GP is exposed to that GP's organisational risks (key-person, regulatory, strategy drift).
Why concentration sometimes works: experienced managers in narrow segments often outperform diversified funds because focused expertise generates better deal selection. The challenge is distinguishing genuine specialist edge from accidental concentration that just hasn't been tested by a downturn.
How professional LPs manage concentration: - Position-size limits per LP agreement — fund LPAs typically cap single-position size at 10-15% of fund commitments. - Sector caps — funds may include sector concentration limits in the SIPO or LPA. - Geographic spread — institutional LPs allocate across NZ + AU + global private markets to mitigate single-market exposure. - Vintage diversification — committing to multiple fund vintages over 3-5 year cycles spreads timing risk.
Concentration in the FMA's "vulnerability" framework: the FMA's annual Conduct and Culture review highlights single-fund / single-manager concentration as a "vulnerability" warranting enhanced due diligence in wholesale offers.
