Hubris is a term used in economics to refer to a dangerous behaviour that emboldens an investment professional to take risks that are beyond what is appropriate in their present circumstances.
From ancient Greece, Elisabeth Roudinesco in an article on the history of the concept 'hubris' published in Le monde des Livres on May 3, 2022, describes the term to refer to excessive attitudes that are opposed to temperance or reason. These attitudes could be of passion, pride, outrage, crime or transgressions.
