How can I get data for all DJIA stocks for last 100 years?

[2weels]

I'd like to try some algorighms on actual stock data. How can I get data for all the stocks on the Dow, or on NASDAQ? Can it be obtained for free?

Thanks.

Check out at top right of first table “ US historical constituent”

Can check pricing page. Pretty reasonable for a long delisted list.

Seems like before 1928 there were less than 30 stocks in the DJIA

Backtesting is important, but people often go overboard. Whether or not your algorithm worked in 1930 (or 1980!) will have little bearing on how it does today.
