Definition

Diversification

Spreading risk across multiple perils, geographies, and trigger types to reduce portfolio volatility.

Example

How it works in practice

An ILS fund allocates capital across Florida hurricane, California earthquake, Japanese typhoon, and Australian cyclone risks. In any given year, it is unlikely that all four regions experience major catastrophes simultaneously. By spreading its exposure, the fund reduces the chance that a single event wipes out a large share of its portfolio value.
