Dear Statalist members,

For my thesis, I need to merge daily security data to Fundamentals annual data. I know that this topic about merging Compustat annual and daily has been dealt with in the past, but I have tried several ways, but I could not come up with the results until now. Hopefully, can somebody help me?
I could not merge the files containing 471 variables and 38921 observations with the files containing 13 variables and 13947724 observations.
