We all know that Daily data is split-adjusted but Intraday is not. Following a couple recent large spinoffs (GE > GEV and MMM > SOLV), I noticed that IQFeed had applied a split-type adjustment for these that matched my adjustment that I apply for intraday data. I continued investigating S&P 500 and Nasdaq 100 stock histories and found that adjustments for Spinoffs have been applied in about 30 cases.

I attached a spreadsheet with my spinoff findings. This isn't an exhaustive study but I've been following the S&P 100, 500, and Nasdaq 100 stocks. With a few exceptions that I can't quite reconcile the workbook has 3 spreadsheets:

1. The first are the spinoffs for which IQFeed has already applied the adjustment. Nothing needs to be done here, it's just for reference.
2. The next sheet is a list of about 65 other spinoff that I request to be applied to the Daily data. If its not possible to apply these corrections, then I want to know that, and I'll just do it myself for all of our customers.
3. The last sheet of "Errors" is a short list of spinoff that IQFeed may have applied an adjustment for, but they don't match my calculation. More investigation required.

Mainly, I'm looking for action on #2.

To be clear, I'm only talking about adjustments for Daily data. (Just forget that I even mentioned Intraday.)

It's been a few days. Can someone reply?

I have sent your findings to our data team for review. I should have let you know this sooner, I apologize for that.

Great. I'll wait for the good news!

This is still being researched by our data team. There was a lot of data so it will take some time to fully investigate. I will post here when there is an update.
