Statistical properties of short term price trends — •Paweł Sieczka and Janusz Hołyst — Faculty of Physics and Center of Excellence for Complex Systems Research Warsaw University of Technology, Koszykowa 75, PL 00-662 Warsaw, Poland

We have investigated properties of short term price trends (starting from 10 sec.) at various stock markets. The results point out that there is a significant difference between real markets and the random walk model. This difference is due to price autocorrelations that influence a probability of trend extending. This probability depends in a specific way on a length of the current trend period. The results for different markets are compared.
