This chapter aims to test the hypothesis of an efficient market, in its weak form, in the stock markets of Brazil, China, South Korea, USA, Spain, Italy, in the period from December 2, 2020 to May 12, 2020. The results show that the market efficiency hypothesis is rejected in all markets. In corroboration the DFA exponents show long memories, which put in question the market efficiency, in its weak form, suggesting that the stock markets analyzed show some predictability. In conclusion, investors should avoid investing in stock markets, at least while this pandemic lasts, and invest in less risky markets in order to mitigate risk and improve the efficiency of their portfolios.

The development of the capital markets is changing the relevance and empirical validity of theefficient market hypothesis. The dynamism of capital markets determines the need for efficiency research. The authors analyse the development and the current status of the efficient market hypothesis with an emphasis on the Baltic stock market.

The article presents an analysis of the concept of efficient market. Also, the market efficiency evolution is reviewed and its current status is analysed. This paper presents also an examination of stock market efficiency in the Baltic countries. Finally, the research methods are reviewed and the methodology of testing the weak-form efficiency in a developing market is suggested.
