The chapter opens by criticizing confident technical-analysis language the author once accepted. It then develops deception through examples from nature and competition. Its skepticism concerns untested explanations, not proof that every quantitative price study is useless.
Remove the room for hindsight
If several people identify different patterns on the same chart, the label alone is a weak basis for measurement. Define the entry event and outcome horizon before inspecting later prices. A visual impression may generate the question, but it is not the answer.
Worked example
“A strong support bounce” leaves several choices undefined. “A close above yesterday’s high after a decline of at least 2%” is one possible measurable rule, introduced here only as an illustration.
Case connection
A vivid chart supports many explanations. Compare each story with participant and transaction evidence.
GameStop: investigate the popular story
Source-grounded facts
SEC staff found short covering contributed during some intervals, but positive sentiment sustained GameStop’s weeks-long rise.
Context
GameStop’s January 2021 rise drew attention to retail participation, short selling and possible feedback loops. The SEC staff report examined transactions to test several competing explanations.
Outcome
The report attributed the sustained weeks-long rise to positive sentiment rather than short covering alone. This is a staff interpretation of a specific episode, not a complete account of every participant’s private motives.
- Staff observed some intervals when heavily shorted accounts bought shares while the price rose.
- Those purchases were a small part of overall buying, and prices stayed elevated after their direct effect would have faded.
- Staff did not find evidence that a gamma squeeze explained GME’s January episode.
Case analysis
A rising chart can be consistent with several stories. State what each explanation predicts about who buys, when they buy and how long its direct effect should last. Then compare those predictions with transaction evidence. A story becomes stronger by surviving a competing explanation, not by using more vivid language to describe the same chart.
