Let’s use the great PerformanceAnalytics package to get some insights on the risk profile of the MAN AHL Trend Fund. It’s a program with a long track record – I believe in the late 80′. The UCITS Fund NAV Data can be downloaded from the fund webpage as xls file- starting 2009.

First let’s import the data into R. I’m using a small function, to import .csv which returns an .xts object named ahl.

#Monthly NAV MAN AHL
  a=read.table(“ahl_trend.csv”,sep = “,”,dec = “,”)
  a$date = paste(substr(a$V1,1,2),substr(a$V1,4,5),substr(a$V1,7,10),sep=”-“)

next we would like to have the monthly returns

monthlyReturn(x, subset=NULL, type='arithmetic',
           leading=TRUE, ...)
 which we store in retahl.


Next, I usually plot the chart.Drawdown to get a visual idea, if the product is designed for my risk appetite.


Annualized Return                  0.0212
Annualized Std Dev                 0.1246
Annualized Sharpe (Rf=0%)          0.1702
Semi Deviation                        0.0254
Gain Deviation                        0.0222
Loss Deviation                        0.0222
Downside Deviation (MAR=10%)          0.0289
Downside Deviation (Rf=0%)            0.0241
Downside Deviation (0%)               0.0241
Maximum Drawdown                      0.2478
Historical VaR (95%)                 -0.0521
Historical ES (95%)                  -0.0748
Modified VaR (95%)                   -0.0573
Modified ES (95%)                    -0.0730
