Why the spikes in price compare MSFT ro EBAY ?

[Ian McVicar <icm63@xxxxxxxxxxx>]

 MSFT :
http://www.askresearch.com/cgi-bin/intraday?index=%24COMP&intraday=symbol&symbol=MSFT&country=USA&size=640x480&frequency=1+minute

EBAY:
http://www.askresearch.com/cgi-bin/intraday?index=%24COMP&intraday=symbol&symbol=EBAY&country=USA&size=640x480&frequency=1+minute

These are two charts at http://www.askresearch.com/, for some reason MSFT has
large one minute spike tails of price....WHY is the result of decimalistion or
something ? EBAY is free of that spike .

Any ideas

Ian
