Syntax
SELECT [[westclintech].wct].[SystematicRisk](
<@Ra, float,>
,<@Rb, float,>
,<@Rf, float,>
,<@Freq, int,>)
Description
Use the aggregate function SystematicRisk to calculate the Systematic Risk. Systematic Risk is calculated as:
\rm{SystematicRisk=\beta\times{s_m}}
\rm{\beta=\ BetaCovar(Ra-Rf,Rb-Rf)}
\rm{s_m=\ s_{Rb-Rf}\times\sqrt{freq}}
Where
{"columns":[{"field":"column 1"},{"field":"column 2"},{"field":"column 3"}],"rows":[{"column 1":"Ra","column 2":"=","column 3":"asset return"},{"column 1":"Rb","column 2":"=","column 3":"benchmark return"},{"column 1":"Rf","column 2":"=","column 3":"risk-free return"},{"column 1":"freq","column 2":"=","column 3":"periodicity of returns"},{"column 1":"s","column 2":"=","column 3":"sample standard deviation"}]}
Arguments
@Ra
the asset return for a period; the percentage return in floating point format (i.e. 10% = 0.10). @R is an expression of type float or of a type that can be implicitly converted to float.
@Rb
the benchmark return for a period; the percentage return in floating point format (i.e. 10% = 0.10). @R is an expression of type float or of a type that can be implicitly converted to float.
@Rf
the risk-free return for the period in floating point format (i.e. 10% = 0.10). @Rf is an expression of type float or of a type that can be implicitly converted to float.
@Freq
the period in which @Ra, @Rb, and @Rf are expressed. For example, a @Freq of 1 would indicate that the returns are annual; 4 would be quarterly, 12 would be monthly and 252 would be business-daily. @Freq must be of a type int or of a type that implicitly converts to int.
Return Type
float
Remarks
If @Ra or @Rb IS NULL it is not included in the calculation.
If @Rf IS NULL it is set to zero.
If there are no non-NULL rows in a GROUP then NULL is returned.
@Freq must be greater than zero.
If @Freq IS NULL then @Freq is set to 12.
Examples
In this example we have monthly returns for an asset, its benchmark, and risk-free returns for the last three years.

To calculate the systematic risk for each manager we run the following SQL.
SELECT wct.SystematicRisk(man1, bmark, rf, 12) as man1,
wct.SystematicRisk(man2, bmark, rf, 12) as man2,
wct.SystematicRisk(man3, bmark, rf, 12) as man3,
wct.SystematicRisk(man4, bmark, rf, 12) as man4,
wct.SystematicRisk(man5, bmark, rf, 12) as man5,
wct.SystematicRisk(man6, bmark, rf, 12) as man6
FROM #managers;
This produces the following result.
