Many charts of the Dow Jones Industrials that show the 1987 crash use weekly closes. On these charts, the December bottom is below the October bottom. If you look at a long-term daily chart of the DJIA, you'll see that the October bottom was below the December bottom. Because the October low did not occur on a Friday, it is not there on the weekly chart. At Topline we don't think that removing information from a chart helps the viewer to understand the data better.
