Where can I find historical stock price data for companies that are no longer listed on any exchanges?
For example, I would like historical stock prices for ATYT prior to their acquisition by AMD. I would like a source that is free and available online.


Finding the price of a stock on a certain date in the past does not necessarily mean rifling through old copies of the Wall Street Journal. Here’s a link to look for the data from other sources…

I expect your best bet is the microfilm copies of the WSJ at a convenient library. Try a University Library if your local library does not have the old copies.
