An example of a non-insurable risk is speculation. Speculation is a financial risk that involves buying or selling assets in the hope of making a profit, but there is no guarantee that the investment will be successful. Because the outcome of speculation is uncertain, it is not possible to accurately assess and underwrite the risk, and therefore, it cannot be insured. Other examples of non-insurable risks include events that are outside of human control, such as war or natural disasters, which are referred to as "acts of God."
