Hi
It depends on whether you can sort the list or not. if you can't sort the list, and assuming that list is in A1:A100, I would enter this in B1:B100 (starting from B1):
=IF(ISERROR(VLOOKUP(-A1,$A
in this way you have blank cells or the values that have an exact negative match in the list. It is still necessary to copy and paste values only and sort column B to get the non-blank values grouped together though.

You can use conditional formatting. Select the values and choose the menu command Format->Conditional Formatting. Select Formula is and enter this formula:
=COUNTIF(A1:A100,-A1)>0
where A1:A100 is the selection and A1 is the active cell (first cell selected). Choose a color to highlight cells that have a matching value.
