The only meaningful numbers are market cap changes or percentage changes. The numbers for the market cap are much bigger than most people can think of, and you need to know what the absolute value is to know how big of a relative change it is.
What bothers me are per share prices. I don't remember the precise value of any particular stock, so IBM drops $13 means nothing to me. Also that a stock is $500 a share, so it must be good is another thing you see a bunch, so it must be great is another fallacy I see all the time; when really all that matters is the market cap not how many pieces it is divided into.
Share prices have a strong psychological affect on many investors. This is why you will see increased buying and selling around certain price points and not market cap.
