Hello Statalist,
I have encountered an issue while running SP500 firm WRDS event study. I have done this before, but I am not sure why it keeps giving me the usual error:
"ERROR: Insufficient valid data to run an event study. Please review your input file to ensure that: the ID (e.g. CUSIP) and date format (MM/DD/YYYY) in your file match what you selected, dates are market trading days.
the sample has 8-digit cusip and I convert that using CUSIP converter to make sure it is accurate. The date is the same as the format DD-MMM-YYYY (i.e., 24-JUN-2015). Below is how my data looks like. Btw, I also tried other date formats. The remains the same.
By the way, I want to test the SP500 around this date
