When I was an institutional broker in a former life, I was a believer in the merits of using technical analysis. I found that it was a very useful tool that complemented the much more mainstream tools generically referred to as fundamental analysis.

Many don’t put much stock in technical analysis. I understand that. A former institutional client of mine once said: “At the bottom of the ocean are many sunken vessels, and in each one there is a chart room filled with charts.” But there is another perspective. The markets represent the aggregate interaction of many investors. Their attitudes, philosophies, and behavioral patterns on many levels are predictable….and repetitive.

One of the greatest technicians of all time was a man named W. D. Gann (1878-1955). He had tremendous success predicting market moves much in advance. Legend has it that he occasionally sent notes to *The Wall Street Journal*, which accurately predicted tops and bottoms in grain markets months ahead of time.

There are two Gann principles that I have always respected. They are that historical prices alone aren’t predictive unless paired with time; and that the “birth dates” of contracts are of major significance. The birth date is the first day a contract, stock, or grain begins trading. And birth dates that occur during "Fibonacci" years are even more significant. The larger the Fibonacci number, the more significant.

Leonardo Fibonacci, the great 13th century Italian mathematician (1175–1250) created the “Fibonacci sequence” to explain behavior in nature mathematically. History has it that the first question he posed was how many rabbits would be created in one year starting with one pair.

The sequence is actually quite simple. Start with "1" and add the previous number to create the next. So, 1 + 0= 1, 1 + 1 =2, 2 +1 =3, 3 + 2=5, 5 +3 =8….and so on…so the sequence is…0,1,1,2,3,5,8,13,21,34,55,89,144,233 and so on. Mathematicians have been enamored with the sequence ever since. It not only predicted rabbits' explosive reproduction numbers, but accurately measures a wide array of activity and behavior in nature.

Over time, this sequence was used by the master painters to define the dimensions of their paintings. There is something “pleasing” to humans about the proportions defined by the sequence. Think of 3x5 index cards, or how many times most people knock on a door, or ring the phone….3 is the most common, 5 is second. Humans have 5 senses, five fingers. The patterns of the spiral of sunflowers seeds also can be explained using the sequence.

The Fibonacci sequence also gives us the “golden mean” used in many mathematical calculations. The golden mean is 1.61—which is arrived at by dividing a Fibonacci number by the previous number. For example 89/55=1.61. Going the other direction 55/89=.61—which is how market technicians come up with Fibonacci retracements. Skip a number, 55/144=.38, the next retracement. I could go on with the many combinations used by market technicians. Suffice it to say the harmony of these numbers in nature was the cornerstone of much of W.D. Gann’s work to explain grain markets' pricing behaviors.

The other application of the sequence by Gann was with respect to time. Consider how 21- and 55-day moving averages are a favorite of purist technicians. It was this aspect of time when applied to the “birth dates” of markets that I wish to concentrate on—specifically for the Treasury market.

On August 22, l977, the Chicago Board of Trade started trading 30-year bond futures. This year, August 22 falls on a Monday. It will be the **THIRTY-FOURTH ANNIVERSARY** (34 is a Fibonacci number). My goal is not to make a market prediction as much as to share a fascinating possibility.

The next Fibonacci number is 55, it's a difference of 21, which could determine the length of the next cycle. If this Gann cycle is accurate, it may mean a cycle high in price, a cycle low in rates in the Treasury complex could occur possibly on August 22, or thereabouts. Another way to look at this would be, that it may be the **BEGINNING OF A 21-YEAR CYCLE** in lower prices, higher rates.

Simply stated, if this measure were truly predictive, it could mean the end of a bull cycle and the beginning of a bear cycle in Treasury prices. This may not mean that once the cycle's low yield is reached, the market will immediately reverse. Yet, if you were to look back , over time it could show up as an important turning point in the market.

There have been several large changes over the years in the bond contract, like a coupon change 11 years ago from an 8-percent coupon to the current 6-percent coupon. I can’t say if that would distort Gann’s theories. At the margins I hope readers find this interesting. Yet for those of you out there that believe in a higher order to human behavior, this could prove to be a prediction that W.D Gann might have mailed into CNBC if he was alive today.
