Hubris is the characteristic of excessive confidence or arrogance, which leads a person to believe that they may do no wrong. The overwhelming pride caused by hubris is often considered a flaw in character.

In the financial world, hubris is considered a dangerous quality that emboldens an investment professional to take risks beyond what is appropriate for their situation. While such risks may pay off at times, any person who shows such behavioral flaws can easily find their gains erased by dramatic losses.
