The name leap year probably comes from the fact that while a fixed date in the Gregorian calendar normally advances one day of the week from one year to the next, the day of the week in the 12 months following the leap day (from March 1 through February 28 of the following year) will advance two days due to the extra day (thus leaping over one of the days in the week).
DEFINITION of 'Return'. The gain or loss of a security in a particular period. The return consists of the income and the capital gains relative on an investment. It is usually quoted as a percentage.
Rate of return is a profit on an investment over a period of time, expressed as a proportion of the original investment. The time period is typically a year, in which case the rate of return is referred to as annual return.his means if reinvested, the return over 12 months would compound to give a return of 12.7%. As another example, a two-year return of 10% converts to an annualized rate of return of 4.88% = ((1+0.1) (12/24) - 1), assuming reinvestment at the end of the first year.
