You have been given the following return information for a mutual fund, the market index, and the risk-free rate. You also know that the return correlation between the fund and the market is 0.97.
Year | Fund | Market | Risk-Free | |||
2011 | –15.20 | % | –30.50 | % | 3 | % |
2012 | 25.10 | 20.10 | 4 | |||
2013 | 13.00 | 11.20 | 2 | |||
2014 | 7.40 | 8.00 | 5 | |||
2015 | –1.56 | –3.20 | 2 | |||
Calculate Jensen’s alpha for the fund, as well as its information ratio. (Do not round intermediate calculations. Enter the alpha as a percent rounded to 2 decimal places. Round the ratio to 4 decimal places.)
Year | Fund (F) (%) | Market (M) (%) | Risk Free Return (RF)(%) | [(R)-E(F)] | [(R)-E(F)]^2 | [(R)-E(M)] | [(R)-E(M)]^2 |
2011 | -15.20 | -30.50 | 3 | -20.9480 | 438.8187 | -31.6200 | 999.8244 |
2012 | 25.10 | 20.10 | 4 | 19.3520 | 374.4999 | 18.9800 | 360.2404 |
2013 | 13.00 | 11.20 | 2 | 7.2520 | 52.5915 | 10.0800 | 101.6064 |
2014 | 7.40 | 8.00 | 5 | 1.6520 | 2.7291 | 6.8800 | 47.3344 |
2015 | -1.56 | -3.20 | 2 | -7.3080 | 53.4069 | -4.3200 | 18.6624 |
28.74 | 5.60 | 16.00 | 922.0461 | 1527.6680 |
- Arithmetic Average Return of Fund =
= 5.748%
- Arithmetic Average Return of Stock =
= 1.12%
- Arithmetic Average Return of Stock =
= 3.20%
- Standard Deviation of Fund =
= 13.5797%
- Standard Deviation of Market =
= 17.4795%
- Beta of Fund = Correlation(F,M)*S.D.of Fund*S.D.of market/(S.D.of market)^2
= 0.97*13.5797*17.4795/(17.4795)^2
= 230.2454/305.5336
= 0.7536
Now, Calculating Jensen's Alpha:-
Rf = Average Risk free Return = 3.2%
Rm = Average Market return = 1.12%
RRF = Average Actual Fund Return = 5.748%
So, Jenson's Alpha is 4.1155%
_ Information ratio:-
Year | Fund (F) (%) | Market (M) (%) | Differnce of Returns (D) | [(R)-E(D)] | [(R)-E(D)]^2 |
2011 | -15.20 | -30.50 | 15.30 | 10.6720 | 113.8916 |
2012 | 25.10 | 20.10 | 5.00 | 0.3720 | 0.1384 |
2013 | 13.00 | 11.20 | 1.80 | -2.8280 | 7.9976 |
2014 | 7.40 | 8.00 | -0.60 | -5.2280 | 27.3320 |
2015 | -1.56 | -3.20 | 1.64 | -2.9880 | 8.9281 |
28.74 | 5.60 | 23.14 | 158.2877 |
- Arithmetic Average Return of Difference in Return =
= 4.628%
- Standard Deviation of Difference in Return =
= 5.6265%
So, Tracking Error or Standard Deviation of Difference in Return is 5.6265%
Information ratio = (Arithmetic AVerage return of Fund - Arithmetic AVerage return of Market)/Tracking Error
= (5.748%- 1.12%)/5.6265
= 0.8225
So, Information ratio is 0.8225
