You badly missed on my message. By saying that 'educated people' should not look at those graphs, I meant literally that knowledgeable investors know the actual worthiness of the process of pulling another graph from Yahoo. It is worth zero, because playing with graph range can produce any result. Do you get it now or you should continue playing with different graphs? There are other ways to analyze stocks, some of these ways are specific for mining stocks. No one of these ways would use yahoo graphs. Why can't you figure out that disseminating wisdom of the mutual fund holder to mining stock investors looks silly by arrival?
