You can achieve this by using helper column in your raw data
paste below formula and drag till end and use this in your pivot table as sum.
=IF(COUNTIFS($A$2:A2,A2,$B$2:B2,B2,$G$2:G2,G2)=1,1,0)
You can put simply pivot table (value as StdDevp) or convert this =STDEV.P(E3:E33) formula into array with multiple criteria using if function
like
let say
j3 have 111013 (stock)
k3 have 1 (month)
l3 have 2015 (year)
=STDEV.P(IF((($B$3:$B$84=L3)*($C$3:$C$84=K3)*($A$3:$A$84=J3)),E3:E84))
Very nice question,
Excel skills set depends of level of excel knowledge (like formula and understanding of functions and other thinks)

Use below formula in condition formatting
row
= INDEX($A$1:$A$5,SUMPRODUCT(($A$1:$E$5=C9)*ROW($A$1:$E$5)))
col
=INDEX($A$1:$E$1,,SUMPRODUCT(($A$1:$E$5=E9)*COLUMN($A$1:$E$5)))
OK,
why does it include the header? - As we need to check difference (multiple of $5,000) between last paid off and current paid off that why have checked first paid off with header.
why is this not the full range of data? - you can increase range as per your requirement
why that portion...
