Daily Accumulated % Change from January 1, 1990

This image is an example of the type of display that is possible with American Image, Inc.'s JOHO system. It shows 2,592 data points in one comprehensible view.

Image Layout

Each wide column in the panel represents one of the six major petroleum companies in the S&P 500. The names of the companies appear at the bottom of each column.

Each row of the panel (too small to see unless you magnify the panel) represents one trading day. The panel covers all of 1990 and 1991 through the end of August. The dates are labeled down the left side of the panel. We have indicated the dates of the Iraqi invasion of Kuwait and of the initiation of Desert Storm.

Each cell indicates the percent change in the closing price of a company's stock measured relative to the closing price on January 2, 1990. The legend at the right shows how to translate the colors in the panel into percent change. We use warm colors (yellow, red, white) to indicate positive percent changes, and cool colors (green and blue) to indicate negative percent changes.

The columns (companies) are sorted so that the company with the lowest percent change on the last day is at the left, and the one with the highest is at the right.

Image Interpretation

Note that the prices the stocks went up rather suddenly about one month prior to the Iraqi invasion, except for Exxon stock. Note that there was another jump in closing price at the beginning of Desert Storm except for Amer Hess. Also, there was another jump around April 12, 1991 that affected all of the stocks.
