FAQ: IPO offer price in ThomsonOne differs from stock price in Datastream?

When you collect IPO data in ThomsonOne you can add the Offer Price to your report. Often researchers then request the stock prices of the IPOs from Datastream and notice large differences.

For example the offer price of Turftrax was 0,40 Pound, but when you request the stock price in Datastream the closing price on the first day is 200 Pound. This is a very big difference, but it can be explained: When you request the Unadjusted Price in Datastream (datatype = UP), you’ll see that the UP was 0,40 Pound as well, but there has been a reverse stock split in July 2009.
