Would you happen to know if other historical data is available as well, such as AT&T pre-SBC acquisition? I'm mainly curious in daily data from the historical Dow 30 components. thanks, Steve

This data exists in our archive but when SBC acquired AT&T, they kept the symbol T for the new company. The pre merger data exists as T also and there is no way to make the old symbol T distinguishable from the new symbol T. Each scenario is different and would need to be addressed individually.

Does this mean that when I query the historical daily data for "T", that I would be getting the original AT&T data until the symbol was switched over, and then I would get the data for the SBC+AT&T stock? Or would the historical daily data for T be SBC?
