Styles & Sectors: Chronology of Events
This type of chart lets you zoom in to look with great
magnification at the financial history of any market over any period
since 1972. Its main purpose is to show the significance of key
events that do not lend themselves to systematic analysis. The dates
of important events straddle the index at the time and place where
they occurred and a news headline is shown alongside. The selection
includes key economic, political, international and market specific
events.
These charts are much larger - around twice the width and three
times the length - to make room for the news headlines. Because
these charts extend well beyond the edges of the page, it is
necessary to use the scroll bars on the right and at the bottom of
the main window to locate the period of interest. If no data is
immediately visible, scroll down till the series appears. The Zoom
facility in Internet Explorer is especially useful here. (See Help >

The index is shown by the bold white line, the explanatory variable,
news headlines in this chart, are shown in yellow text and the dates
are bright green. The month / year divider marks the point at which
each event took place.
In the interests of brevity, initials often replace full names. (See

for explanations)
There are several ways to compensate for losing visibility of the
axes. Firstly to compensate for the timescale at the bottom, the key
dates appear in the plot area at the point where they occur.
Secondly the use of log scales makes it unnecessary to see the value
axes, because the vertical distance between any two points in the
chart reflects the same percentage movement, whatever the index
level.
Furthermore the log scale is the same across all charts of this
type. (See Investor Education > Conceptual Framework >
Chart Features for
further explanation) The values are in any event indicative only, as
each stock market index has been rebased individually in this type
of chart. However, because of the relatively small percentage
movements, the perspective for Global Investors is shown using the
same linear value scales as in other types of chart. These can be
seen by scrolling to either the left or right sides of the chart.
In order to provide the maximum possible magnification, the
treatment of time periods is also different. Instead of the normal
medium and long-term timescales, there are two consecutive periods,
of which the former covers 1972-1986 and the latter covers more
recent history.
In respect of the earlier period, it has not been feasible to
construct a meaningful chart for some emerging markets owing to
exchange controls, hyperinflation or simply a lack of data.
