I'll help you with whichever way you want to do this, I think you'd be better off keeping all the data on one sheet though and just having another sheet where you input the stock symbol and it displayed the data for just that stock, would that work for you?
That sounds good, I'll attach a copy of the data so I can explain what I'm trying to achieve.
The permno is used to identify a company, even if a company changes its name or ticker, this stays the same.
Instead of prices I have gone with returns and market cap.
I first want to clean the data.
I want to use only companies that have data for 30/06/2003-30/06-2018
This is strictly 3778 data points per company, but to be safe let's say that if a permno appears less than 3750 times in the perno column, get rid of all rows with that perno number in the permo column.
Also, sometime there are letters in the "Returns" column. Can we remove all companies that have at least one non-number in that column?
I would like one page with a list of permno and all tickers/company names that are associated with that permno.
Your idea of a searchable page is amazing. If I just type in the permno somewhere and it shows all of the results in order for that company, that would be great.
Before creating a final single-page data set, I would need to check the cleaned data first.
I take back the requirements in my first few posts, the layout in the attached document is fine, all I need is permno, date (in some number format), returns and cap. I think I can figure that out myself
