Apples Macintosh application dashboard has a little thing for following the stockmarket. I seldom look at it, but this weekend I opened the dashboard for another reason and almost fell off the chair when I saw the stockmarket graph.
It appeared to be a downturn to the lowest value in a year, enough to justify fears that fears of a depression could come back. However, a closer look reveals that the value of the index does not match the graph. Also, when looking at the data in 1 day or 1 week view, the downturn does not appear. Only in 1 month or longer plots.
