You ain't seen nothing yet:

I noticed a lot of numbers that were wrong outright last night myself on Google Finance's page. Obviously the source from where MarketWatch and Google Finance are getting their numbers has it screwed up. Take a look at this for instance: http://venkatcc.googlepages.com/ObsceneNumbers.jpg

like veecee said this is usually a data provider problem and seems like it in this case too... Fixing this is a manual process. I have notified the marketwatch.com data team and someone at marketwatch.com should be taking care of this shortly. Apparently over 4k ticker data were corrupted by the provider.

Looks like someone put the decimal in the wrong place:

Marketwatch price: $26.35 Actual Price: $2.63

wait what?

I will gladly sell you some ford stock at 26 bucks a share. Let me know.

this is fixed now :-)
