There are significant differences between the fundamental data shown on yahoo web site and what stores in AB for "Certain" tickers. In my case it is about 5% of the tickers in my database. From the response to this thread, I am guessing not many people use fundamental fields in AB. Or perhaps they use fundamental fields but they don't use yahoo as data source! If there would have been a big uproar TJ would have fixed it by now.

I don't use fundamental data but looking at the AQ literature there is a difference in the type of data that is downloaded between basic and extended modes. For example, one of the differences that you note is the 'current dividend'. This is the annual dividend/share which basic downloads as 'Dividend Per Share' and is correctly shown as $1.92 for KYN. According to the same AQ literature 'Dividend Per Share' is not included in the extended download so the download correctly shows nothing for this category. I have not gone through the other categories but after taking into account the differences in data that is downloaded between the two modes as specified in the AQ literature do you still see unexplained differences?

Here is an example of "some" fundamental info for just one ticker KYN... there are many such data descripencies problems that can be found: Yahoo AmiQuote AmiQuote KYN Basic Extended 1.92 1.92 0 Current Dividend N/A 275,140 275,140 Forward Dividend 0.18% 582,600,000% 582,600,000% % Held by Insiders 17.50% 0.18% 0.18% % Held by Institutions 7/2/2010 7/2/2010 7/8/2010 Ex-Dividend Date 7/8/2010 7/9/2010 7/9/2010 Dividend Date o The first column are the value in Yahoo. o The second column are the values in AB after downloading Basic Fundamental data using AmiQuote. o The third column are the values in AB after downloading Extended Fundamental data using AmiQuote. Ton: Since you seem to use a different download program for retrieving Yahoo fundamental data for AB...what are your results for the above example. Also, what is the alternative program you are using to download yahoo fundamental data into AB?

If AmiQuote is unreliable and if Yahoo gives the correct data than I should not have the same errors when downloading Yahoo data with other downloaders. But I do ... Please prove me why AmiQuote is unreliable just by showing that downloading the same data from Yahoo and a different downloader gives different results.

The Basic Data changes/deletes the Extended Data and when Extended Data is loaded it changes/deletes Basic Data. Many people have said that the Yahoo data is unreliable....it's probably more because AmiQuote is unreliabel and doesn't load info correctly. #...@* > ------------------------------------ **** IMPORTANT PLEASE READ **** This group is for the discussion between users only.
