This paper analyses the Portuguese stock market since it reopened in 1977, with a special focus on the evolution of the statistic and stochastic characteristics of the market return throughout this 36 year period. The market return for the period of time between 1977 and 2012 (September 28th) is estimated and then compared with the return that would have been achieved with Government bonds and treasury bills, which allows us to confirm that the hierarchy of return / risk across the different financial instruments is verified. The market risk premium for this 36 year period is also estimated and a comparison with other markets is performed, suggesting that the Portuguese market’s risk has not been compensated by an adequate return. The study also examines the evolution of the Portuguese market’s volatility in the 1977-2012 period and compares it with other markets, showing the existence of extremely high peaks during the first 11 years, but indicating a downwards trend throughout the whole period under analysis. Finally, the correlation between market returns for Portugal and for other countries and the degree of integration are estimated and their evolution throughout time is assessed, leading to the conclusion that the performance of the Portuguese stock market has become increasingly correlated with major European markets – correlation with some markets close to 0.70 from 2000 onwards-, but that country-specific risk factors are still relevant.

Vinciguerria lucetia es uno de los recursos mesopelágicos más abundantes e inexplotados. En el presente trabajo, mediante el análisis de 774 gónadas (597 ovarios y 177 testículos) colectados en el BIC José Olaya durante los Cruceros de Investigación de agosto 2010 y diciembre 2011, se establece una escala histológica de madurez gonadal para hembras, que ha permitido validar una escala macroscópica de 5 estadios. En el caso de los machos, se identificaron 4 estadios de madurez gonadal tanto microscópicamente como macroscópicamente. Esta escala permite facilitar la obtención de datos reproductivos en diversas circunstancias como prospecciones de campo y muestreo a bordo.
