Dead Stocks

 


Sample Search: Give the Datasream code for Calstar, a delisted stock.

Step 1

  • When a stock is delisted, Datastream stops using the equity's ticker symbol and assigns a code to it. To find the code for a dead stock, use the online CODE program (the clickable Code Lookup does not contain dead stocks) to find Datastream codes. Type CODE at the prompt, and when the input page appears type the name of the stock in the first field. In the second field (the one that asks you to specify the type of instrument you are looking for) type D, for "Dead". Press Enter.

    The following output appears on the next screen:

CODE THE FOLLOWING POSSIBLE MATCHES HAVE BEEN EXTRACTED:
NAME CODE MNEMONIC CUR NOTES
CALSTAR 511938 U$ DEAD NO DAILY PRICES

    Finally, the above search can be performed in the "Expert" mode by typing in the parameters for the code search on one line in the program number box, e.g., CODE CALSTAR,D.







 

Things to Remember

  • Stocks that move from one exchange to another are not "de-listed". The entire data series for a stock that switches from one exchange to another may be found using the code associated with it in its new location. Likewise, when a name change occurs, the history remains on that one code and only the equity's name is changed.
  • You can use the codes of dead stocks to plot charts using any of the 401 chart programs. Type 401A 511938,,,-10Y at the prompt and you will see a price chart of Calstar over the last 10 years, with the price going flat in early '92.
