Humans have evolved to be “pattern seeking” animals. Historically and evolutionarily, it was better to have false positives than false negatives - that stick on the ground mistakenly being misidentified as a snake was safer than assuming it wasn’t. So, we tend to see random craters on the moon as a face, a few stars in a row as a belt or a sword, that sort of thing. Neither the face nor the belt nor the sword are really there, of course, but there’s usually little harm in seeing them as such. Astrology, Tarot Cards, I Ching, etc. are all based on pre-scientific “false positives”, finding patterns and meanings where none exist.
Speaking of Astrology, do “Leo’s” exist? Of course, in the trivial way we can define them into existence based solely on birth date. But do they exist in a meaningful way that allows us to assign personality traits to people born under certain signs? Of course not.
What I’m leading up to is do “inside candles” exist? Do “bearish gravestone doji’s” exist? Going back in time, how about “Elliott Waves” or “Head and Shoulder formations”. Of course they exist in the trivial sense that we can define criteria for them. But beyond that, do any of them have precise, repeatable predictive abilities? And would such patterns still show up even on a random number plot?
Here’s Apple’s daily chart from Friday.
Can anyone here draw lines and arrows and circles on this chart to show at what point in the day’s gyrations money could have been made? Where are the candles and doji’s and waves? And what if I told you that chart was, in fact, not Apple’s daily price moves but was randomly generated. Could you prove it wasn’t? And what would that tell you about our innate drive to find patterns in even random data?
Anyway, I enjoy the intellectual challenges such discussions provide. And it gives me something to do while Karen is in the DMV getting her motorcycle endorsement added to her license. (Yay!) I try to be a skeptic, but not a cynic, so I do my best to stay open to the fact that someone, somewhere, may someday beat the system and get very, very rich using technical analysis or “The Strat” or whatever the latest scheme is. But in the immortal words of James Randi, “I doubt that!”
