why does google finance show the nasdaq composite way up but yahoo! finance shows it slightly down?
user
first - google's snapshot -  then - yahoo -  i took these snapshots because they will not exist on line after the market opens, and without this context, your question won't make sense. with the two snapshots you can see, yahoo shows the after hours trades and not just the official market close for the day. the amount it's down is exactly tracked from the close shown on google. now you know.
