Detecting Positive Feedback Trading when Autocorrelation is Positive

Zagreb International Review of Economics and Business, 2013, vol. 16, issue 1, 93-101

Abstract: The temporary convergence of beliefs and actions is a possibility. Positive feedback trading as a stock exchange trading strategy is commonly used as one of the oldest theories about fi nancial markets. Sentana-Wadhwani model was used to test Positive feedback trading. Even though the model supposes that low volatility is associated with positive autocorrelation and high volatility is associated with negative autocorrelation, empirical research for small and young emerging stock exchange shows that high volatility is followed by positive autocorrelation and positive feedback strategy. Accordingly this is evidence in favour of behavioral over traditional fi nance. Investors prefer to follow positive feedback strategy, ignoring fundamental values. JEL Classification: G10; C5
