I take you are using -egen-, have you looked at
-tssmooth_ma-. Something
like:tssmooth ma foo_ma = foo, window(12) would
produce a 12 lagged period
moving average. The window option allows you to
vary the lags and the
forward terms.
There are also several ideas for calculating moving
averages in the FAQ at
http://www.stata.com/support/faqs/stat/moving.html
that might be useful.
