Informal; a phrase used to describe the difference between a high
risk portfolio and a low risk portfolio. One with a high risk portfolio eats well because there is a possibility of a high
return, granting the
investor a more luxurious lifestyle. On the other hand, one with a low risk portfolio sleeps well because he/she does not need to worry about the possibility of losing one's
investment in the way one taking more risks does. See also:
Markowitz portfolio theory.
