While Dalbar showed us how investors returns suffered, we were left wondering why investors acted as they did.

    The answer to the 'why' question may now be found in a recent study showing the part genetics play in a person's investment behavior. The 'Nature or Nurture' study found that up to 45% of a person's investment behavior may be attributable to genetics. Some genetic influences are good while others are not.
