It has been the frequent contention of the writer that a chart as a basis for speculative ventures is ridiculous, but a diagram framed for the purpose of pointing out certain facts, or inciting the student of speculative affairs to investigation of causes is a different matter. No interested person can look at the accompanying chart without being struck at once with the decline of 1903 following the steady advance of the preceding years. If this observation incites intelligent investigations as to the reasons for the reversal, much good may result. On the other hand, the fallacy of operating on mere mechanical records of the past is shown by the same diagram. If the chart had been handed to one of the mechanical traders in 1902 he would have argued that the average price of each year marked the approximate low point of each succeeding year. It certainly does look convincing, but what follows? The infallible system not only fails to work, but reverses itself, and the average price of 1902 becomes the approximate high price of 1903 and 1904. At about the time the system player has gathered enough figures to go on, a change occurs. No intrinsic merit attaches to any kind of diagram, they being merely convenient forms for tabulating history. Some interesting coincidences occur in the chart; most remarkable is the exactly similar size and position of the circles representing the years 1901 and 1903. In no instance did the high or low points of any integral stock correspond in these years, but the total footings were identical in each case. The speculator may extract some value from the diagram by observing that opportunities for profits of forty or fifty points did not occur during the entire period. The extreme possibilities in any one year were 33 points, and much less on the average. If the trader had purchased or sold Composite at an average price, his possibilities of profit would have been limited to about 15 points in any one year. This does not accord with accepted theories. The ordinary speculator who pursues his operations for ten or fifteen points successfully is almost certain to believe that much more profit lies before him, that he is only getting started. There is a reason for this; the public trader takes for his barometer some security which has been conspicuous for its extended fluctuations; he naturally notices and remembers it to the exclusion of the rank and file of stocks. For example, every active participant in speculative affairs knows that Copper had a range of 75 points in a single year, 1901. He bases possibilities too much on this sort of knowledge without reflecting that Copper was a cardinal exception, and that in order to participate in such movements he must throw caution to the winds, and deal in stocks which offer no degree of safety.
