Thanks Snake, looks like that one is the most comprehensive one so may as well spend a little extra if it's good.
Thanks Snake, I haven't read the DuPlessis book but it sounds very helpful. Snake, you mention myths being dispelled, is it possible for you to expand on what you mean with respect to P&F and the du Plessis book?
Another important aspect of performance measurement is the element of time.
The back and forth movement of this component of the performance measurement process is recorded across the horizontal X-axis on the chart. A new column is recorded whenever a reversal of relative performance exceeds the minimum absolute amount. This converts the horizontal X-axis from the measurement of time to the measurement of alternations of trend. The alternation of trend is a function of the stock’s volatility and that is a proxy for the stock’s risk. Therefore the X-axis can be characterized as measuring risk and not time.
Hidden Order?
The stock of Best Buy was chosen for this analysis because its performance over the year 2003 was among the top 100 performing stocks in the Market Dynamics database. The time period covered by this study is 253 days, or one full year.
The lower chart is a 3-point, point-and-figure chart of the relative strength of BBY over the past year. This chart has been cropped to focus on only the record for 2003.
The BBY point-and-figure chart shows an amazingly regular upward progression with only one significant correction. BBY remained above the 45-degree bullish support line during the entire time period covered. This suggests a regular or systematic process at work to steadily propel the stock price higher, relative to the S&P 500 during this time period.
The upper chart is a histogram of the daily percent changes in the price of BBY over the past year. The histogram shows the characteristic bell shaped curve that is usually produced by a random process. The sample is slightly skewed to the right and the average daily price change is .33% per day over the past year. During this time, 54% of the days were up and 46% of the days were down””very close to 50-50.
It is striking that the raw data looks so completely random. Yet the point-and-figure chart produced from that data looks so orderly. It’s as if there was an invisible hand guiding the stock upward in a persistent and regular pattern. This example clearly shows the results of the highly effective transformation of the raw data produced by the three-box, point-and-figure methodology.
The relative strength of the stock shows the characteristic saw-tooth, back and forth action and, in this example, the upward thrusts were greater than the downward reactions as the relative strength worked its way steadily higher. The point-and-figure chart clearly shows the ability of the point-and-figure methodology to remove the noise from the data.
The positive days were larger than the negative days, so the relative strength upward trends tended to accumulate to higher levels and the downward reactions turned out to be mild. When the relationship between the up days and the down days changes, the direction of movement on the chart will change. There are many examples of orderly patterns among the best performing stocks. There also appear to be orderly patterns when the trend turns down. It is amazing that random data could be transformed into such an orderly progression on the point-and-figure chart.- 99
Timmy,
It doesn't really give a typical myth busting rundown on PF charting but rather gives a very good introduction to what they are, before it goes into the nitty gritty. In the introduction I learnd a lot.
It is interesting to see how they evolved also, not created, originally not for charting
I believe you need to read more than one book though. Overall I am happy with it.
