*[Some] people in US and UK face huge financial hit if fossil fuels lose value, study shows.*

The businesses that own fossil fuel facilities would lose stock value, and the owners of the stock would lose the wealth of owning that stock.

If we stop the development of fossil fuel infrastructure and extraction facilities, the undeveloped reserves will lose their value. But that is likely to happen gradually as measures are taken and made firm.

Investors and pension funds can avoid being hit by this by divesting from fossil fuels.
