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.

Excellent suggestion! I use quantmod functions for other analysis - dont know why this slipped my mind.

I use Yahoo! sparingly - but its currently the ONLY free source for Russell ( the actual index - if you have historical data stored you can use IWM as a proxy)

Here's the code :

#install.packages("tidyquant") I commented it out - you will need to install if you dont have it already

library(tidyquant)
symbol="^RUT"
df <- tq_get(symbol, get = "stock.prices", from = "1980-01-01")
