A lot of market research and inquiry is generally an attempt to predict the future based upon what happened in the past. I decided to go back and have a look at one of my old HUI charts to see what has occurred since my original markups. My charting software allows me to save the drawing instructions, and I had a file I last saved on January 27, 2004 which seemed like ages ago. So here's the chart, I extended a few of the trendlines and increased the scale to accomodate the rise in the HUI, other than that, it's the way I drew it in 2004 with the new data added. It was an interesting exercise.

PS, the trend is up and should remain so for the next ten years.
