There are plenty of cases where Google puts their product right under your search, then the results. So they are effectively taking the first search rank for themselves. You can call it whatever you want, but putting your item right above the top item is really just making your item the top item. Search "stock yahoo" and the first thing right under your search is a Google Finance summary and a link to Google Finance. Then comes the real first result, which is Yahoo Finance. If Google didn't insert their product right under your search, Yahoo would be the top result and receive an immense traffic boost.
No, Google puts the ANSWER first if it has it, otherwise a list of links that might have the answer.
Google Finance does not rank higher than Yahoo Finance in your example. The stock onebox that appears (which, you'll note, Bing also does) has a list of links to Google Finance, Yahoo Finance, and MSN Money. Bing only links to MSN Money fwiw, so Google is "more fair" than the competition here anyway.
And if you do a search for what's obviously a stock ticker, like AAPL, you'll actually see Google goes "Onebox with answer + links to google finance, yahoo, and MSN money followed by finance.yahoo.com search result", whereas Bing is "MSN money onebox followed by a link to google finance"
So clearly Google Finance's high position is justified regardless, as other search engines put that result first.
