How does an insurance company BEST achieve a good spread of risk?

Limiting the number of risks written restricts the insurer’s ability to diversify its portfolio. A small number of risks increases exposure to loss from any single event, which can lead to significant financial strain if multiple claims arise simultaneously. This strategy does not effectively spread risk.

While insuring in multiple locations can help mitigate risk, the overall impact is still limited if the number of risks remains small. Fewer risks mean that even with geographic diversity, the potential for loss is high if any single event affects those limited policies. Thus, this approach does not provide the best risk spread.

Concentrating a large number of risks in one location increases vulnerability to localized events, such as natural disasters or economic downturns. This concentration can lead to significant losses if an adverse event affects that area, counteracting the goal of achieving a good spread of risk.
