Append time series
Posted: Tue Mar 17, 2020 7:38 am
Hello,
I would like to append new data point(pull from Datastream) to the existing series. For example, I have US stock returns going back form 1926 to 1990. From 1990m1 I would like to pull S&PP500 returns and append to the original US stock returns time series. What is the best way to do that? Thanks.
