Answer #1

Portfolio return can be calculated in absolute terms and in annualized percentage terms. Following formula are used for both the terms of portfolio return:

Portfolio Return (simple) = (Capital gain from stock + Income from stock)

Where-

Capital gain from stock = [(Value of stock at the end of the period - Value of stock in the beginning of the period) / Value of stock in the beginning of the period[

Income from stock = Dividend per share * Number of shares

Portfolio Return (annualized) = Portfolio return (simple) / Total Investment in all stocks in the beginning of the period

Now let us calculate the above two using given data of name of company, number of shares, beginning of year price, end of year price and dividend per share

Statement showing Individual Return

Company

Shares (A)

Beginning of Year Price (B)

Dividend per share (C )

End of Year Price   (D)

Beginning Value    E = (B * A)

Capital Gain F = [(D-B) * A]

Income     G = (C * A)

Total Return   (F + G)

Portfolio Return (simple) = (Capital gain from stock + Income from stock)

Portfolio Return (simple) = $5,632.53

Portfolio Return (annualized) = Portfolio return (simple) / Total Investment in all stocks in the beginning of the period

Portfolio Return (annualized) = $5,632.53 / $22,005.54

= 0.256 or 25.6%

Now, let us calculate the portfolio beta using the below mentioned formula:

Portfolio Beta = ( Security Beta * Security Weights )

Shares (A)

Beginning of Year Price (B)

Beginning Value     C = (B * A)

Weights D = (C / Total of C)

Portfolio Beta = ( Security Beta * Security Weights )

Portfolio Beta = 1.048

Hence the portfolio beta matches with the actual results given in the question.

The required rate of return can be calculated using Capital Asset Pricing Model which can be calculated as follows:

Required Return = Risk free rate + (Market rate - Risk free rate)

Where:

= 1.048 (portfolio beta)

Risk free rate is not given, then let us assume that Risk free rate is 0

Market rate is also not given, then let us assume that Market represents the bunch of shares given in the question and hence the market rate can be assumed as portfolio return i.e. 25.6%

On putting these figures in the above formula, we get -

Required Return = Risk free rate + (Market rate - Risk free rate)

Required Return = 0 + 1.048 (25.6 - 0)

Required Return = 26.83%

Hence the portfolio is not earning its required rate of return.
