(Bruner‚ p. 239‚ 2007). At the time of the case‚ four main estimatesof equity market risk premiums (EMRP) were: 6.4% = Geometric mean over T-bills 4.7% = Geometric mean over T-bonds 8.4% = Arithmetic mean over T-bills 6.4% = Arithmetic mean over T-bonds For the purpose of analysis we will use 6.4% EMRP‚ thus (E(Rm)-Rf) = 6.4 %.() The cost of equity is determined by the company’s levered Beta (). This is calculated according to the ‘Hamada equation’:

survey dishonestly. This example closes the chapter‚ teaching readers to always assume that the sample has a bias. The second chapter focuses on averages. It states that there are actually three types of averages: mean‚ median‚ and mode. Mean is the arithmetic average. Median is the name given to the midpoint of the date. Finally‚ mode is the data point that occurs the most often in the data. Thus‚ the type of average used can alter the results of the statistics. The next chapter explains how sample data

Zero is a unique number that means “empty space” and that which represents a number and its use for computation. It was conceived from the Hindus from India. The earliest recorded evidence was found on the Gvalior inscription‚ however‚ the zero we are accustomed to today‚ came much later. Zero has two basic uses: to mean empty space or to represent a number used for computation. It is especially important in positional notations. Positional notations‚ is a numerical system in which each position

thanks in large part to the tech bubble. We chose to calculate average returns as 12x the monthly average return. This annualizes our return‚ which provides a better representation of returns by including more data points to perform analysis. The arithmetic calculation provides an impartial estimate of future return because it is always more than the geometric. All assets classes reported positive returns from 1990 through 1999‚ while the S&P 500 index had the highest annual average return of 17.7%

upon the nature of the data set and its distribution (normal vs non-normal). The mean (denoted by x) is calculated by dividing the sum of the individual data points (where Σ equals “sum of”) by the number of observations (denoted by n). It is the arithmetic average of the observations and is used to describe the center of a data set. mean=x= One of the most basic purposes of statistics is simply to enable us to make sense of large numbers.

Thus‚ a 1 percentile probability will produce a smaller VaR than a 5 percentile probability. 2. The geometric return represents a compounding growth number and will artificially inflate the annual performance of the portfolio. 3.
