Getting data for delisted RIC using reference data

Hi Refinitiv Support Team,

I am trying to download data from companies whose shares have been DELISTED from trading at an exchange in the past. In the following you find under:

  1. code that tries to download stock prices for YAHOO that was delisted in 2017. This code gives an error message and returns no data.
  2. Code that succeeds in downloading stock price data for IBM, that is a company that is still traded until today. This code returns valid output data.

Would you mind letting me know how to download stock price data for delisted companies?

Thanks a lot for your help!

1.

import refinitiv.data as rd
import pandas as pd
rd.open_session()
 
startDate="1997-19-19"
endDate="2017-06-16"
RIC_RD="YHOO"
 
dfRD=rd.get_history(universe=f"{RIC_RD}",start=f"{startDate}",end=f"{endDate}",
               fields=["HIGH_1","TRDPRC_1","LOW_1","OPEN_PRC","NUM_MOVES","ACVOL_UNS"],
               adjustments="unadjusted")

2.

import refinitiv.data as rd
import pandas as pd
rd.open_session()
 
startDate="1996-01-02"
endDate="2023-01-31"
RIC_RD="IBM"
 
dfRD=rd.get_history(universe=f"{RIC_RD}",start=f"{startDate}",end=f"{endDate}",
               fields=["HIGH_1","TRDPRC_1","LOW_1","OPEN_PRC","NUM_MOVES","ACVOL_UNS"],
               adjustments="unadjusted")

@ns3481

Thank you for reaching out to us.

I think the delisted RIC for Yahoo Inc is AOL^F15.

You can contact the content support team directly via MyRefinitiv to verify this RIC.

@Jirapongse , thank you for the swift response.


1.Is there a way I can get the delisted RICs for all stocks, say all constituents of a major index (think S&P 500 or Russell 1000). We face this issue for hundreds of stocks.

2. From your query it appears as though the stock data starts from 2009, when it should start much earlier, from say 1997.

Thanks a lot for your help!
