Google fisuggest is just my term for the new feature Google Finance has not an official one.

Google Finance has now a suggestive feature for your Finance based searches, so like Google suggest for searches you also have Google Finance suggest you financial term searches.

When you start typing a few words in Google Finance search box, it generates a drop-down of companies whose name or stock symbol matches the search keywords. Clicking on the names or symbols will lead you to the actual results for those stock options.

Check out the new aha, old Google suggest at Google Finance.
