Please complete your example:

-- Table DDL.
DECLARE @Product_Pool_2 TABLE ( GroupID INT );
DECLARE @product_Prices TABLE ( ProductID INT );

-- Insert your test date here.
---

-- Your Logic.
DECLARE groupid CURSOR
FOR
    SELECT  GroupID
    FROM    @Product_Pool_2;
DECLARE @groupid INT;

OPEN groupid;
FETCH NEXT FROM groupid INTO @groupid;
WHILE @@FETCH_STATUS = 0
    BEGIN
        PRINT N'Groupid' + @groupid;

        WITH    Normalized
                  AS ( SELECT   PARSENAME(REPLACE(P.ProductID, '-', '.'), 2) AS GroupID ,
                                PARSENAME(REPLACE(P.ProductID, '-', '.'), 1) AS SizeID
                       FROM     @product_Prices P
                       WHERE    PARSENAME(REPLACE(P.ProductID, '-', '.'), 2) IN ( SELECT    G.GroupID
                                                                                  FROM      @Product_Pool_2 G )
                     )
            SELECT  ( SELECT    '/' + I.SizeID
                      FROM      Normalized I
                      WHERE     I.GroupID = O.GroupID
                    FOR
                      XML PATH('')
                    ) AS Sizes
            FROM    Normalized O
            GROUP BY O.GroupID;


        FETCH NEXT FROM groupid INTO @groupid;
    END;

CLOSE groupid;
DEALLOCATE groupid;

-- Result: Please post the desired output of those two statements for the above sample data.
SELECT  *
FROM    @Product_Pool_2 PP;

SELECT  *
FROM    @product_Prices PP;

You'll need to do a much better job defining what you're asking here.
Specifically, define ' RESULT FROM THE CONSUMPTION', and in the above four code blocks the bottom three appear to be identical.

A CTE can be also used to update a column:

WITH    Normalized
                  AS ( SELECT   PARSENAME(REPLACE(P.ProductID, '-', '.'), 2) AS GroupID ,
                                PARSENAME(REPLACE(P.ProductID, '-', '.'), 1) AS SizeID
                       FROM     @product_Prices P
                       WHERE    PARSENAME(REPLACE(P.ProductID, '-', '.'), 2) IN ( SELECT    G.GroupID
                                                                                  FROM      @Product_Pool_2 G )
                     ),
SizeInfo AS (
            SELECT  ( SELECT    '/' + I.SizeID
                      FROM      Normalized I
                      WHERE     I.GroupID = O.GroupID
                    FOR
                      XML PATH('')
                    ) AS Sizes,
O.GroupID
            FROM    Normalized O
            GROUP BY O.GroupID)
UPDATE G
SET KK = SI.Size 
FROM @groups G 
INNER JOIN SizeInfo SI ON G.GroupID = SI.GroupID;
