Hi,
I have a dataset with stock returns for around 50 stocks, which I attached to the question. The time period is from 1962-2016. I would like to reshape it.
Right now it looks like this:
ID RET dates
10000 0.5 date1
10000 0.2 date2
10001 1 date1
.
.
.
10050 0.3 last date of stock 50
I would like it to look like this
date 1 date2 date3 .....
RET1 of stock1 RET2 of stock 1 RET3 of stock 1
REt1 of stock2 RET2 of stock 2 RET3 of stock 2
. . .
. . .
. . .
Data description
ID the id of diffrent stocks
dates daily observation
RET daily returns.
The ID variable is not really needed in the new table it just has to be 1 row.
Optimali the date variable would be the names of the column but if it is not possible it can also be the the first row.
Does someone know how to do that?
Thanks in advance

  • Convert the dataset to the much more modern and supported table using dataset2table.
  • Look at unstack()
