Malkiel's argument makes some big generalizations about technicians.
Every trader who refers to charts does not follow trends, as was pointed out earlier in this thread.
Every trader, even every trend follower, does not trade in the same time frame. For one trader, a 5 minute trade might be too long, for another, they may be fully expecting to stay in a trade for months or years.
Within each time frame, no two traders will act identically.
I do agree that there is no inherent edge in charting. That certainly doesn't mean charting is of no value to a trader. It is a tool to be utilized, more or less skillfully, by each trader.
