Historical data going back >30 yrs

Discussion in 'Data Sets and Feeds' started by NoWorries, Jun 19, 2006.

  1. Many data vendors offer EOD data going back 15-20 yrs. Can anyone recommend a source for EOD securities data going back much longer (1950~), ideally split-adjusted and (most important) including delisted stocks?
  2. that's very helpful, thanks. It seems Yahoo does not show delisted securities though, so it's a first step. Eventually, I'm looking for a data source that includes delisted securities as well, in order to avoid survivorship bias.
