I want to perform an ML analysis on NASDAQ, based on historical fundamentals.
Suppose I want to take a temporal window of 10 year and quarterly data.
I have a question:
I suppose I should know the composition of Nasdaq in the previous years. I mean, its symbols in 2012,2013 and so on.
There is a service, API, or a free source doing this?
What is the common practice?
Thank you Francesco
