SQL Server upside frequency of asset returns


UpsideFrequency

Updated: 31 January 2016


Use the aggregate function UpsideFrequency to calculate the upside frequency of asset returns. UpsideFrequency is calculated as the ratio of the number of rows where the asset return is greater than the minimum acceptable return to the total observed asset returns.
Syntax
SELECT [wct].[UpsideFrequency](
  <@R, float,>
 ,<@MAR, float,>)
Arguments
@R
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.
@MAR
the minimum acceptable return in floating point format (i.e. 10% = 0.10). @MAR is an expression of type float or of a type that can be implicitly converted to float.
Return Type
float
Remarks
·         If @R IS NULL it is not included in the calculation.
·         If @MAR IS NULL it is set to zero.
·         If there are no non-NULL rows in a GROUP then NULL is returned.
·         @MAR must be the same for all values in a GROUP.
·         Available in XLeratorDB / financial 2008 only
Examples
In this example we have returns for an asset and its benchmark for the last three years. The minimum acceptable return is 0.005.

To calculate the upside frequency for each manager against a minimum acceptable return of 0.5% we run the following SQL.
SELECT
   wct.UpsideFrequency(man1,0.005) as man1
   ,wct.UpsideFrequency(man2,0.005) as man2
   ,wct.UpsideFrequency(man3,0.005) as man3    
   ,wct.UpsideFrequency(man4,0.005) as man4    
   ,wct.UpsideFrequency(man5,0.005) as man5    
   ,wct.UpsideFrequency(man6,0.005) as man6
   ,wct.UpsideFrequency(bmark,0.005) as bmark
FROM
