I am not aware of a running product function, but you can always use
Stata's running sum function, sum(x), to obtain the running product as a
sum of logarithms.
i.e.
.gen prod_run_x = exp(sum(ln(x)))

Does any one know how to multiply two or more values located in the same column but in different rows?
For example, in the first column I have the following information:
Row 1: 2
Row 2: 3
Row 3: 4
Row 4: 2
What I want to do is to calculate:
Row 1 x Row 2 = 6
Previous result x Row 3 = 24
Previous result x Row 4 = 48
