If the present down-swing continues, how much of a correction will we see? A 5% fall will bring it to the 2-year Support Line; a 21% fall to the 5-year Support Line, and a 60% fall will bring it to the 25-year Support Line, lining it up with the bottom of the Dotcom crash of 2000. Perhaps the strength of the American economy will restrain it to the 5-year Support Line; however, once it starts into a down-trend, it may be hard to stop.
