Younger investors take the most risks. It's generally accepted that younger investors, who have more time to let their money ride out the market waves, have a higher tolerance for risk than their older counterparts. New data from investing app Openfolio found that investors under age 25 are taking full advantage of this truth. By analyzing the investments of 2,500 hundred of their user profiles, Openfolio found that the youngest investors are indeed taking more risk ... but they don't have much to show for it.
