This chapter builds upon the extensive prior literature on return predictability by studying 10 frontier market indices. In general there is modest evidence of return predictability in frontier markets. More evidence is found in favor of predictability than would be expected under the null of no predictability. However, there is not widespread evidence in favor of any one predictor across countries; rather, return predictability is clustered in specific countries. In terms of economic value we find that in general, modest economic value can be generated. The difference between our predictability and economic value results are likely due to differences in weighting of observations; for example, in the economic value models the extreme forecasts are winsorized when portfolio weights are determined. The cross-country relationship between market characteristics and predictability/economic value is also examined. Predictability is stronger in countries with more liquid markets and higher GDP per capita.

Notes: Table 10.2 reports the in-sample predictability of stock returns at the 1-month horizon. Our in-sample predictability tests consist of regressions of one period ahead stock returns on current predictor variables. For each country-fundamental pairing, the top value is the slope coefficient and the adjusted R2 is given in curly brackets. The symbols ***, **, and * denote statistical significance for the slope coefficient at the 1, 5, and 10% levels, respectively, for a two-sided test; critical values are bootstrapped from the empirical distribution.

Notes: Table 10.3 reports the OOS R2 in percentage points. The OOS R2 gives the percentage by which the regression model beats the HA benchmark. Note that the link between OOS R2 and Theil’s U is OOS R2 = 1 − U2. Statistical inference is based on the McCracken’s (2007) MSE-F test, which assesses if the forecast error from the regression model is smaller than the forecast error from the HA regression. Critical values are based on a bootstrap procedure under the null hypothesis of equal forecast accuracy. The symbols ***, **, and * denote statistical significance at the 1, 5, and 10% levels, respectively, for a one-sided test.

Notes: Table 10.4 reports the economic significance of regression forecasts. It reports bootstrap significance levels that have been adjusted for data mining. The symbols ***, **, and * denote statistical significance at the 1, 5, and 10% levels, respectively. Utility gains are reported as percentage points and are annualized by multiplying monthly values by 12. Utility gains are calculated for an investor with mean-variance preferences under assumptions of a relative risk aversion coefficient of 3 and a weight limit for the risky asset of no less than 0 and no more than 1.5 (as in Campbell and Thompson, 2008). We forecast the return and use the current market risk-free rate to calculate the excess return. AVall combines forecasts using the average of all individual forecasts. AVall takes the average (unsmoothed) portfolio weight of each portfolio and then applies the weight limits on the risky asset.

Notes: Table 10.5 reports the economic significance of regression forecasts. The table reports bootstrap significance levels that have been adjusted for data mining. The symbols ***, **, and * denote statistical significance at the 1, 5, and 10% levels, respectively. We limit the weight in the risky asset to be no less than 0 and no more than 1.5 (as in Campbell and Thompson, 2008). This test utilizes the certainty equivalent measure of Goetzmann et al. (2007). The values reported are in percentage points and are annualized. Gains are measured using a certainty equivalent measure of abnormal performance, which is more robust to manipulation motives of agents.

Notes: Table 10.6 reports the correlations between measures of forecast performance and country characteristics. Panel A reports results for the correlation between country characteristics and OOS R2 for the unrestricted (restricted) model. Panel B reports results for the correlation between country characteristics and economic value, where we examine the unrestricted (restricted) model GISW measure for the unrestricted (restricted) model. The country characteristics are GDP per capita [GDP(pc)], stock market development (MV/GDP), total financial sector development (MV + PC/GDP), turnover (calculated as Vol/MV), and move (calculated as proportion of stocks that move each day divided by the total number of stocks). Country characteristics are measured over the 2005–14 OOS period. The symbols ***, **, and * denote statistical significance at the 1, 5, and 10% levels, respectively.
