Purpose: Stock market participants use technical analysis to seek trends in stock price charts
despite its doubtful efficiency. We tested whether technical analysis signals represent typical and
common cognitive biases associated with the continuation or reversal of the trend.

Methodology: We compared investors’ opinions about the predictive power of technical analysis
signals grouped into five conditions: real technical analysis signals associated with trend continuation
(real momentum signals) or trend reversal (real contrarian signals), fake momentum or fake
contrarian signals, and fluctuation signals.

Findings: Investors assigned larger predictive power to real and fake signals associated with trend
continuation than to signals associated with trend reversal. Fake signals, which represented cognitive
biases, elicited similar predictions about trend continuation or reversal to real technical analysis

Originality: Market players assess momentum signals to have greater predictive power than contrarian signals and neutral signals to have the least predictive power. These results are independent of whether technical analysis signals were well-known to investors or made up by experimenters. The hardwired propensity of our brains to detect patterns combined with the non-natural environment of the stock market creates the illusion of expertise that is not easy to dispel.
