Hello, AmiQuote is just the specialized web browser (downloader) that does NOTHING but issue HTTP request and download data from Yahoo.
Yahoo Basic and Extended information is a result of TWO different requests coming from two different pages. Yahoo Basic information is coming from "Download Data" link on that page: http://finance.yahoo.com/q?s=KYN i.e.: http://download.finance.yahoo.com/d/quotes.csv?s=KYN&f=sl1d1t1c1ohgv&e=.csv While Yahoo Extended is coming from "Key Statistics" page here: http://finance.yahoo.com/q/ks?s=KYN+Key+Statistics As you can see first link (Basic) does NOT include "% held by insiders" or "% held by institutions" or "forward dividend" therefore your findings about "Basic" mode are incorrect, because you quote data that do NOT exist in "Basic Fundamental" download. The only that is available from "Basic" source is DIVIDEND and this one is downloaded as it should. Other fields are simply not present in "BASIC" page. What you are telling other people on the list is false, probably left-over from any previous downloads that you did, because fields that DO NOT exist in given data source are left untouched. With regards to "Extended" mode, data are retrieved from http://finance.yahoo.com/q/ks?s=KYN+Key+Statistics UNLIKE all other datas downloaded by AmiQuote, this does NOT come in computer-friendly, comma-separated form. It is instead formatted to be "human readable" and its layout is changed from time to time by Yahoo. Every change Yahoo does on that page may result in problems. The data you got are incorrect simply because of one addition that Yahoo did, they started adding commas as "thousand separator" and because of the fact that COMMA is also field separator, it causes trouble during importing of such file because thousand separator used by Yahoo is interpreted as field separator. In this particular case the problem is because PROFIT MARGIN for KYN is 1,913.39%. Because of that comma in profit margin you get problems (only for symbols that have profit margin higher than 1000%). It is rare, don't you think. Of course this special (rare) case for Extended Fundamental mode needs to be fixed, but how come you go so far to saying that all data downloaded is unreliable is beyond me. I guess that bashing the program makes you happier ?
