We compare the performance of the time-series (TS) and cross-sectional (CS) momentum strategies in the US and China. The CS strategies by default are zero net investment strategies, whereas the TS strategies take on a time-varying net long position in risky assets. In the US, we confirm that the...

We test the behavioural theories of overconfidence and underreaction on cross-sectional (CS) and times-series (TS) momentum returns in the Japanese stock markets. Both CS and TS momentum returns are large and significant when the market continues in the same state and turns into losses when the...

Recent evidence on the relationship between investor sentiment and subsequent monthly market returns in China shows that investor sentiment is a reliable momentum predictor since an increase (decrease) in investor sentiment leads to higher (lower) future returns. However, we suggest that...

We search for differences in both unconditional and conditional momentum returns of Islamic and Non-Islamic stocks and test implications of competing behavioral theories that aim to explain momentum returns. Our results show that there is no significant difference in momentum returns between...

A recent theory of information uncertainty (IU) postulates a negative (positive) relationship between IU and future returns (momentum returns). We extend this theory by showing that its predictions could be conditioned by differences in behavioral biases induced by culture. We find that greater...

We re-examine the presence of rational speculative bubbles in the Singaporean and Indonesian stock markets in light of contradictory results in the literature. We employ a mix of descriptive statistics, explosiveness tests and duration dependence tests for an expanded dataset from 1970 to 2013...

Recent studies suggest that momentum returns are conditioned by market states, but we find that China is different. First, we find that momentum returns in China exclusively follow DOWN markets contrary to the U.S. evidence. Second, the absence of momentum returns following UP markets in China...

Recent evidence on momentum returns shows that the time-series (TS) strategy outperforms the cross-sectional (CS) strategy. We present new evidence that this happens only when the market continues in the same state, UP or DOWN. In fact, we find that the TS strategy underperforms the CS strategy...

We test the behavioural theories of overconfidence and underreaction on cross-sectional (CS) and times-series (TS) momentum returns in the Japanese stock markets. Both CS and TS momentum returns are large and significant when the market continues in the same state and turns into losses when the...

Recent evidence on the relation between momentum and idiosyncratic volatility (IV) in the U.S. is mixed. We verify the relation between momentum and IV in China and find at best, no relation supporting the view that idiosyncratic risk is not a significant arbitrage cost for momentum returns....
