The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

Depending on the data you are looking for iShares has historical month end holdings on their site.

For IWF you could go to ishares.com - Ishares russell growth ETF
and click to the holdings section. Above the actual holdings you will see a drop down with options for the past four months.

If you need to go back further than that you will need to tinker a bit. The actual url will be something like this
'... www.ishares.com/us/products/239706/ishares-russell-1000-growth-etf/xxxxxxxxx.ajax?fileType=csv&fileName=IWF_holdings&dataType=fund&asOfDate=20231229 '
but the value xxxxxxxxx is an api key that comes from somewhere and probably related to a cookie on the machine. If you know your browser and can look at the url that the browser calls to retrieve an historical date it is visible there. Copy that url and change the date and you have it. I should point out that the dates are last market day of the month. I've also seen some python libraries that can supposedly retrieve this data but I've never used one.
