Abstract

In this paper we examined adaptive markets hypothesis (AMH) using three factors we assumed that affect weak-form of market efficiency: observation period, time horizon represented by rolling window sizes and data aggregation level. We have analyzed market value weighted index MONEX20, which is proxy from Montenegro equity market, over 2004-2011 period. Rolling window analysis with fixed parameter in each window is employed to measure the persistence of deviations from a random walk hypothesis (RWH) over time. Actually, using rolling sample approach we checked whether short-range linear dependence is varying over time. This method was applied on the first order serial autocorrelation coefficients (AC1), as well as on runs test, since evidence on non-normality properties of MONEX20 suggests using non-parametric test. The evidence was found that all three factors impact degree of weak-form Montenegro equity market efficiency which has serious consequences on profit opportunities over time on this market.

Sežetak

U ovom radu je ispitivana hipoteza o adaptivnosti tržišta kroz analizu tri faktora za koje smo pretpostavili da imaju utjecaja na slabu formu efikasnosti tržišta: period promatranja, vremenski horizont predstavljen dužinom pokretnog prozora i razina agregiranosti podataka. Analiza je provedena na tržišno ponderiranom indeksu MONEX20 koji predstavlja proxy za crnogorsko tržište akcija u periodu od 2004-2011. godine. Metoda pokretnih prozora s fiksnim parametrima u svakom prozoru pojedinačno je primijenjena kako bi izmjerili odstupanja od hipoteze slučajnog hoda tokom vremena. Zapravo, pomoću ove analize je ispitivano variranje kratkoročne linearne ovisnosti prinosa iz prethodnog i tekućeg perioda. Metoda pokretnih prozora je primijenjena na autokorelacijski koeficijent prvog reda (AC1) i na test znakova (neparametarski test), s obzirom na to da serija podataka indeksa MONEX20 ne dolazi iz normalnog rasporeda. Analiza je dovela do zaključka da sva tri faktora utječu na razinu slabe forme efikasnosti crnogorskog tržišta akcija, što ima ozbiljne konsekvence na mogućnosti ostvarivanja profita tokom vremena na ovom tržištu.
