Where to download list of all common stocks traded on NYSE, NASDAQ and AMEX?

Is it possible to download a list of stocks that belong to a specific exchange (e.g. NASDAQ, AMEX, NYSE)? The tseries package has a function to download the price history of a stock, but how to get all the stocks of an exchange?

  • $\begingroup$ Unfortunately, TTR on CRAN is still broken. I don't know of a function to download symbols from any other exchanges. $\endgroup$ Aug 16, 2011 at 15:23

I think you are confused about "markets". Of the three you listed, only NASDAQ is an exchange, the other two are information services. For the three major US exchanges, you go to: (NASDAQ, AMEX, NYSE):

http://www.nasdaq.com/screening/company-list.aspx

Pick the one you are interested in and answer their silly robot barrier "puzzle" and download the csv file, in which the ticker symbol is the first column.

Edit: With TTR_0.20-3 from r-forge, the list appears more complete than with the prior version:

require(TTR)
SYMs <- TTR::stockSymbols()
#Fetching AMEX symbols...
#Fetching NASDAQ symbols...
#Fetching NYSE symbols...
 table(SYMs$Exchange)

##  AMEX NASDAQ   NYSE 
#   308   2820   3261 

Whereas the csv file from NASDAQ for NASDAQ had 2820 symbols. On the other hand the TTR authors may have eliminated some of the duplicates, warrants or outdated symbols.

    $\begingroup$ TTR::stockSymbols does this for you. See the two links in my comment to the OP. $\endgroup$ Aug 16, 2011 at 14:30

  • $\begingroup$ @Dwin: looks like you're using TTR_0.20-2. stockSymbols is broken in that version. I really need to push an update to CRAN. Also, it doesn't eliminate any symbols. $\endgroup$ Aug 16, 2011 at 16:17
  • $\begingroup$ Yes. My system reported that as the current CRAN version. $\endgroup$
