MAGNITUDE & DIRECTION In mathematics, systems of linear equations are used to construct complex spans that can shift across multiple dimensions. In their most basic form, each construct is made up of a series of vectors which are basically line segments. A vector, by definition, has two components - magnitude and direction. On Friday, the S&P closed down for the day - which by itself is not particularly noteworthy, except for the fact that it had also closed down in each of the previous 8 days as well. This was the first time this has happened since 1980... a somewhat historic move in terms of duration.
