# Fast extraction of earliest NYSE listing date with FinancialData

I would like to know the fastest way to find the earliest listing date of a given symbol on the New York Stock Exchange - for example,

FinancialData["AAPL", All][[1,1]]


returns

{1980,12,12}


Which is correct, since AAPL was first listed on the NYSE on 1980/12/12.

This method is extremely slow, however, given one has to get the entire time series for a company in order to access its first element. Is there a faster way to do this?

FinancialData["AAPL", "IPODate"]

FinancialData["GE", "IPODate"]

• Thanks! Is there a general way to do this for all financial time series given by Mathematica, rather than just stocks? The above solution works for "AAPL", but returns Missing[NotAvailable] on an ETF such as AAXJ. – Brian Burns Dec 14 '18 at 19:11
• @BrianBurns, I don't know a general way that for works for all FinancialData seris. – kglr Dec 14 '18 at 19:27
