I'm looking to build a spreadsheet containing a lot of historical stock data. And I mean A LOT. Specifically, I'm hoping to get each ticker in its own sheet, then have each row correspond to one day in that stock's history. For each day, ideally, I'd like to have some data, possibly an opening price, closing price, high, low, and volume. I'm also looking for more advanced stuff, like earnings per share, spending on R/D, if possible. Basically, more data is better, and I'm looking to gather data on at least 1,000 different stocks. How would I go about doing this?
