Happy Fibonacci Day!
Happy Fibonacci Day!
Hey hey hey! It's Fibonacci Day!
In the Fibonacci sequence, each number is the sum of the two preceding numbers  ex. 1, 1, 2, 3, 5, 8, 13, 21, 34 and so on...
The golden ratio is 1.618. If you divide a number in the Fibonacci sequence by the preceding number, you'll get something close to the golden ratio. This works better for larger numbers later on in the sequence (not so great for 2 and 1...).
You may, on occasion, have noticed someone mention a thing called "Fibonacci retracement" (either in jest or complete seriousness). This is a technical analysis (TA) term. TA is sometimes referred to as finance "wizardry". It's all about trying to spotting patterns in charts. Fun times!
The Fibonacci retracement is about using the golden ratio to try to figure out how down a drawdown will go (or how up a rally will go), and identifying levels of "support" or "resistance". I don't know if it's any good at this.
If you ever wondered what on earth that person was talking about, now you know.
Happy Fibonacci Day! Have you snuggled a snail shell or hugged a tree today? There's still time.

I don't get it! But happy fibonacci day to you too!
Re: Happy Fibonacci Day!
Also known as Leonardo of Pisa, he is popularly known as Leonardo Fibonacci. Fibonacci is a contraction of filo Bonacci, meaning the son of Bonaccio.
Date Sequence
November 23 is celebrated as Fibonacci day because when the date is written in the mm/dd format (11/23), the digits in the date form a Fibonacci sequence: 1,1,2,3. A Fibonacci sequence is a series of numbers where a number is the sum of the two numbers before it. For example: 1, 1, 2, 3...is a Fibonacci sequence. Here, 2 is the sum of the two numbers before it (1+1). Similarly, 3 is the sum of the two numbers before it (1+2).

I guess it all could be much worse. 
They could be warming up my hearse.

Re: Happy Fibonacci Day!
As it happens, the inverse of my ratio of U.S. stocks to international stocks is almost exactly 1.618. Does that mean I have a Fibonacci portfolio?

What a coincidence! It must mean that. You are in harmony with the universe.Florida Orange wrote: ↑Wed Nov 23, 2022 9:44 pmAs it happens, the inverse of my ratio of U.S. stocks to international stocks is almost exactly 1.618. Does that mean I have a Fibonacci portfolio?

OP: "In the Fibonacci sequence, each number is the sum of the two preceding numbers  ex. 1, 1, 2, 3, 5, 8, 13, 21, 34"
Today is 11 23 ... first 4 digits of the Fibonacci sequence.
Pi day = 3 14. Eat Pie!
EDay (Eulers Number) = 2 17.
Yellow Pig Day is important to math nerds.

Re: Happy Fibonacci Day!
I don’t celebrate until 11/23/5813. Let’s hope the US doesn’t change to day/month/year notation before then.
Re: Happy Fibonacci Day!
I don't think so. The constant e = 2.71828...
In some cultures (e.g., Chinese), they do year/month/day.
In that case, we missed our moment on 1123/5/8 13:21:34 (although it was John Bogle's "minus 806th" birthday).
We'll get another chance, however, on 11235/8/13 21:34:55 (birthday of Janet Yellen... and Danny Bonaduce).
You're right, Fibonacci numbers are kind of fun.

On 01/12/35 (December 1st, 2035), we’ll be sure to celebrate here in Europe (and birthdays for Bette Midler, Richard Pryor and Pablo Escobar).HanSolo wrote: ↑Thu Nov 24, 2022 2:47 amIn some cultures (e.g., Chinese), they do year/month/day.

My car is parked on a street named in honor of Fibonacci (even though he was Pisano).

Re: Happy Fibonacci Day!
Also it makes more sense to provide the big picture information first and then zoom in on the details rather than the other way around.homebuyer6426 wrote: ↑Thu Nov 24, 2022 8:35 am Always preferred year/month/day because it can be sorted alphanumerically.

Re: Happy Fibonacci Day!
I like this better than Pi day. This is a really elevated group we have here…

I'm late. Happy belated Fibonacci Day! I believe my 1940's kitchen is designed around a "Golden Ratio"
