Technical Analysis is the OOP of Stock Market

Technical Analysis is Astrology for men

"I realized technical analysis didn't work when I turned the charts upside down and didn't get a different answer."

~ Warren Buffet

Now I think I know why Warren Buffet doesn't care about timing the market

People will invariably compare the same 1000 dollars being invested in different times, however these 2 are different, the early invested 1000 has grown and therefore is not comparable to 1000 invested today

The time in which one enters does not affect the future of the stock performance

So the thing you should consider is whether the company is doing good and whether the stock price reflects it

In fancy terms would be that the value of money changes with time

Pythagoreas plucked a string at different lengths and discovered that a string sounds similar to the same string with half the length, which creates something called an octave (there are 8 notes within an octave)

A string with half the length has double the frequency

Take for an example the note

A4 (Note A in the 4th Octave) = 440Hz

A5 = 880Hz

Then he tried to create different notes by trying other ratios, an octave was 2:1 ratio, the smallest integer ratio within the same octave was 3:2 (3:1 is in another octave) which would be called the fifth

Then he tried to do a 3:2 again, but it would lie outside of the octave, so he would half the frequency

He would repeat it until he got a total of 8 notes

This method made some really nice ratios but at the end there were some ugly ratios like 256:243

Western music is fundamentally based on ratios, ugly (large integer) ratios (also called intervals) create a bad sound like the tritone, which had a ratio of 729:512
