Seems like someone made a booboo at the close of the NASDAQ last Thursday, dropping Google shares $350.

The supposed details of this massive error started at the close of NASDAQ when Google trading ended at 4pm with $387.12 a share. Shortly after closing, Google made an announcement that they had better then expected earnings, but less then the quarter before. 4:02 pm hit, and Google's shares dropped down to about $364, then gained steadily to $391. When the $391 per share price hit, it seems like someone at Nasdaq hit some wrong numbers when an Instinet-ATS order triggered trades at $38 per share between 4:10 and 4:12pm. When that started happening, trades starting going wild between $38.05 and $37.81.

Everything was sorted out and restored shortly after.

The New York Sun has some great stories about traders. Especially one who was told by his broker that his previous 200 share investment in Google at $380 per share, $76,000 total investment, was down $68,400. I'm sure someone at the Securities and Exchange Commission is going to have some major explaining to do.

Earlier this week Yahoo! announced changes that would roll out soon to upgrade aspects of the Yahoo! Finance property. One of these changes, and probably the most significant for daily users, is the completely overhauled Stock Charts.

When Google rolled out Google Finance property, most of the hubbub around their offering was the dynamic charts. These hadn't been seen before anywhere and had a lot of "kewl" factor in them. Even without the kewl charts, Yahoo! continued to be the most comprehensive and most visited financial resource on the web. And now, Y! is rolling out their version of dynamic stock charts with lots of "kewl" factor. Read on for an overview of the new features and my thoughts.

Yahoo! announced in a press release that many long-awaited upgrades were soon to appear on Yahoo! Finance, albeit some only in beta form.

Stock Charts - Google showed us that they could beat Yahoo! to the punch with their Ajaxy charting tools. Unfortunately for Google, the financial users are a pragmatic bunch and need more than the "kewl" factor to make them switch as indicated by Yahoo! continuing to hold the financial users' interest. According to this recent announcement, Y! Finance users will soon be enjoying new kewl dynamic charting tools which take advantage of Flash and DHTML . It pays to be patient, eh?

Message boards - Yahoo! has been upgrading its message boards throughout its many sites for many months now. Yahoo! Finance has seen some of these changes already. Easier search, threaded views and now a rating system to quickly locate quality contributors to the conversation.

Y! Finance Badge - Y! Finance badges for your website have been out in beta for a while now but according to this announcement are out of beta and available for general consumption.

Y! Finance Videos - Y! has made huge advances recently in its ability to serve video regardless of where it is hosted. This is spreading to various Y! sites including Y! Finance. Today's announcement points out that video from several news sources are being made available via the Y! Finance site.

The new stock charts are being evasive. Hopefully we will see them in action soon even if only on a beta version of the Y! Finance site.

UPDATE: The new chart tools are being rolled out to small percentage of users for now. This is much as the ! home page revision was revealed to only a few users for their feedback before opening it up to all Y! home page visitors. More Y! Finance users can expect to see the new chart tools as time goes by.
