Am I being too harsh on a beta product? I don’t think so. Especially if Google wants to slap its name on a financial quoting system, it had better be at least as accurate as many of the existing stock quoting systems out there. That’s the bare minimum expectations. Google even has the gulls to seek an SEC review of stock quote fees.

Google Finance has finally and quietly integrated pre-2001 data into their stock charts. However, as my screen shots show, Google is still suffering from data inaccuracies. I revisited my previous example of a data inaccuracy, and was not surprised to find that it is still not resolved. As of this writing, Yahoo Finance correctly identifies the 52-week high of Tim Hortons (NYSE: TSX) to be $30.35, occurring on Nov. 22, 2006. Google Finance still stubbornly shows $33 as the 52-week high instead. More screenshots after the jump!

As I’ve mentioned Google and Yahoo already, I might as well use Microsoft to showcase an example of Google’s new historical (editor: sorry about the oxymoron) data integration. Among the Big 3 search engines, Microsoft is the deciding non-factor in the stock quotes arena. But Microsoft is a perfect illustration of the new feature as it has the longest stock history.

Since my last post two months ago about Google Finance’s ineptness, they have also integrated optional graphics such as stock splits and dividend information on the charts. Those features were implemented well. Google Finance is still my preferred financial engine for a quick scan / brief overview of stock quotes. Yahoo simply takes too long to load their charts and pages. But for details and accurate information, I have to rely on Yahoo. Google is on the right track, but for such a resourceful company, it’s simply taking too long for them to have gotten here, and yet simple issues are still unresolved.
