Robert, I was making that statement to YF engineers. You are correct that YF does a poor job especially when it comes to timely stock split adjustments. They also perform the split adjustment more than once which really screws up the data.

Yes, I understand that but Yahoo has potentially a good thing going but they mess it up but not getting the basic data correct.
I mentioned this split once before and received the following Yahoo response so I took them straight to the website:
"Product Support (Admin, Yahoo) responded
Thanks for your post, Robert!We are unable to corroborate this request with competitor information. In your next post, can you please provide a URL or example of the split?
Regards,Yahoo Finance Support"
I see this problem with numerous symbols and I am going to start pointing things out. If Yahoo would just monitor https://www.nasdaq.com/markets/upcoming-splits.aspx they would have all current splits.
