Table 5.18: Summary of the results found in Chapters 3, 4 and 5. The table shows for different transaction costs cases the fraction of data series analyzed for which (1) at the 10% significance level a significantly positive estimate of α is found in the CAPMs (3.5), (4.1) and (5.1), if the best strategy is selected in sample, (2) White's (2000) RC p-value is smaller than 0.10, (3) Hansen's (2001) SPA-test p-value is smaller than 0.10, (4) at the 10% significance level a significantly positive estimate of α is found in the CAPMs (3.5), (4.1) and (5.1), if the best recursive out-of-sample testing procedure is applied. Panel A shows the results for the mean return selection criterion and Panel B shows the results for the Sharpe ratio selection criterion. In Chapters 3 and 5 the results are in US Dollars and in Chapter 4 the results are in Dutch Guilders. For entries marked with X no results are computed.
