This sounds like -xtline- after -xtset-.

An -if- condition is needed to do the work of selecting a portfolio

I want to graphically plot the performance (e.g. profitability) of the lowest quintile from t-4 to t+4 with t being the year of portfolio formation. What is the easiest way of doing this without having to do it year by year? Are there some time series commands I should be looking at?
