There are three options available.
My preferred option is to create a pivot table without a helper column.
Create a pivot table of your data.
Set the row to the date field and group it by year. Alternately a 'Year' helper column could be used by adding a column with this formula.
=YEAR(A2)
Set the data items value portion of the pivot table to be the MAX of your 'High' field
Add a helper column titled year with the formula
=YEAR(A2)
Then add a formula for each year
=DMAX(A1:C21,"High",F13:F14)
Enter an array formula for each year using the Ctrl-Shift-Enter keys.
{=MAX(IF(YEAR(A2:A21)=2008,B2:B21))}
