| Tiivistelmä: | The dynamic behaviour of individual shares quoted on the Doha Securities Market (DSM) is investigated in this article. Weekly individual prices over the time span from January 2002 to October 2004 were applied. Robinson's semi-parametric Lagrange Multiplier tests were conducted in search of evidence patterns consistent with long-memory in stock prices. Statistical results did not support the random walk hypothesis, and would seem to lend support for weak-form efficiency in the DSM. |
