Make sql query run faster

Question

Is it possible to make some optimization on such query ?

with t (CurrentPrice, [Weight])
as ( select CurrentPrice, [Weight] from SomeTable where GroupingId = SomeBigIntId )

SELECT MaxExactPrice = ( select MAX(CurrentPrice) FROM t Where [Weight] > 0 ),  
   MinExactPrice = ( select MIN(CurrentPrice) FROM t Where [Weight] > 0 ),
   MaxSimilarPrice = ( select MAX(CurrentPrice) FROM t Where [Weight] = 0 ),
   MinSimilarPrice = ( select MIN(CurrentPrice) FROM t Where [Weight] = 0 ),
   ExactCount = ( select Count(*) FROM t Where [Weight] > 0 ),
   SimilarCount = ( select Count(*) FROM t Where [Weight] = 0 ),
   Count(*) as TotalCount
FROM t

Thank you.

Do this instead. this way you do not have to hit same table 8 different times.

select MAX(CASE WHEN [Weight] > 0 THEN CurrentPrice ELSE NULL END) AS MaxExactPrice
,MIN(CASE WHEN [Weight] > 0 THEN CurrentPrice ELSE NULL END) AS MinExactPrice
,MAX(CASE WHEN [Weight] = 0 THEN CurrentPrice ELSE NULL END) AS MaxSimilarPrice
,MIN(CASE WHEN [Weight] = 0 THEN CurrentPrice ELSE NULL END) AS MinSimilarPrice
,COUNT(CASE WHEN [Weight] > 0 THEN 1 ELSE NULL END ) AS ExactCount
,COUNT(CASE WHEN [Weight] = 0 THEN 1 ELSE NULL END ) AS SimilarCount
,COUNT(*)AS TotalCount
from SomeTable where GroupingId = SomeBigIntId
