Humans are hardwired to identify patterns, and when it comes to the Fibonacci numbers, we don’t limit ourselves to seeking and celebrating the sequence in nature. “And a Fibonacci number has the simplest possible formula, just the sum of the previous two.” “The Golden Ratio’s attractiveness stems first and foremost from the fact that it has an almost uncanny way of popping up where it is least expected,” writes Mario Livio in The Golden Ratio: The Story of Phi, the World's Most Astonishing Number.īut why is this sequence so ubiquitous? “A lot of things in mathematics and probably in the real world are governed by simple recursive rules, where each occurrence is governed by a simple formula in terms of the previous occurrence,” said Ken Ribet, professor of mathematics at the University of California, Berkeley. In spiral-shaped plants, each leaf grows at an angle compared to its predecessor of 360/phi 2, and sunflower seeds are packed in a spiral formation in the center of their flower in a geometry governed by the golden ratio, too. The numbers of spirals in pinecones are Fibonacci numbers, as is the number of petals in each layer of certain flowers. And while phi does not get a pastry-filled holiday like pi, the constant appears in natural phenomena.

The golden ratio, meanwhile, can be written as one-half of the sum of 1 plus the square root of 5. (It has also shown up in counting the numbers of bees in successive generations). Mathematician Eduoard Lucas then gave the name “Fibonacci sequence” in the 1870s to the sequence derived from the rabbit scenario. The sequence’s name comes from a nickname, Fibonacci, meaning “son of Bonacci,” bestowed upon Leonardo in the 19th century, according to Keith Devlin’s book Finding Fibonacci: The Quest to Rediscover the Forgotten Mathematical Genius Who Changed the World. But the pattern was known in India much earlier, possibly even the seventh century.

In Europe, it was the solution to a problem of rabbit breeding described in the book Liber Abaci by the Italian mathematician Leonardo of Pisa in 1202 A.D. The pattern hides a powerful secret: If you divide each number in the sequence by its predecessor (except for 1 divided by 0), then as you move toward higher numbers, the result converges on the constant phi, or approximately 1.61803, otherwise known as the golden ratio. The Fibonacci sequence is a famous group of numbers beginning with 0 and 1 in which each number is the sum of the two before it. While using these numbers to predict market movements is a lot less certain than using it to calculate sunflower seed patterns, the appearance of the sequence in the field of finance is yet another testament to its power in capturing the human imagination. This technique is named after and derived from the famous Fibonacci sequence, a set of numbers with properties related to many natural phenomena. “Fibonacci retracement” is a tool that technical analysts use to guide their outlook about buying and selling behavior in markets. stock market closed out its worst week since 2008 amid coronavirus-related turmoil (before recovering somewhat early the following week), investors were left with a glaring question: Is it all downhill from here? Amid such economic turbulence, some market researchers look to a familiar, powerful set of numbers to predict the future.
