For a while I suspected something was out of whack. And this morning I confirmed it.
Look at a five year graph for RIO on commsec and http://www.google.com/finance?client=ob&q=ASX:RIO for example
commsec reports the high as $124.19 and the low as $23.59
google - which is correct - reports the high as $155.35 and the low as $32.00
Anyone know what the story is here?
