| dc.description.abstract | The paper seeks to illustrate the behaviour of the Portuguese Stock Market from an efficiency perspective. The purpose was achieved by analysing daily stock market returns in terms of distribution and correlation, testing weak form of efficient market hypothesis and identifying its implications. Alternatively, a comparison of warrant market prices with a calculated price was implemented as an assessment of the previous investigation. The application of both methods results in a rejection of the joint hypothesis of weak form efficiency and the random walk model of price behaviour, even though strong signs of a sustained progression towards efficiency are highlighted. | eng |
