Are nominal exchange rates and price levels co-integrated? new evidence from threshold autoregressive and momentum-threshold autoregressive models

The goal of this paper is to examine evidence for co-integration between nominal exchange rates for Canada, the UK, Japan, Germany, Italy and France (G6) vis-à-vis the US dollar, and the relative price ratios using monthly data over the period 1973:01 to 1997:04. Motivated by the fact that exchange rate adjustment may be asymmetric, we allowed for asymmetric adjustment in exchange rates by using the threshold autoregressive model and the momentum threshold autoregressive model. We do not find any evidence of a co-integrating relationship; hence, we fail to establish long-run purchasing power parity.

Momentum profits in Australian listed property trusts

This paper examines the profitability of momentum trading strategies in Australian listed property trusts (LPTs). Monthly value-weighted momentum portfolios are formed using the monthly excess returns of LPTs for the period from 1990 to 2005. Overall the findings confirm that a momentum trading strategy in Australian LPTs is a profitable strategy. More specifically, momentum strategies are profitable after adjusting for variance and downside risk where the momentum returns substantially outperform the benchmark. An analysis using different study periods confirm the findings about momentum. The practical implication from this study is that investors can generate substantial abnormal returns by adopting a momentum trading strategy, particularly with a long strategy (i.e. winner portfolios).

Concurrent momentum and contrarian strategies in the Australian stock market

We investigate the coexistence of momentum and contrarian strategies in the Australian equity market from 1992 to 2011. We show that contrarian strategies prevail in the short-term investment horizon while momentum strategies dominate in the intermediate- and long-term horizons. However, only short-term contrarian strategies significantly outperform the simple buy-and-hold strategy of investing in the market index over the same period. Further examination of these strategies shows that the Australian mining sector undermines the performance of momentum while enhancing performance of contrarian strategies. Lastly, using both parametric and non-parametric approaches, we show that these strategies’ returns are persistent anomalies and not completely explained by standard return-generating models.

Momentum strategies for Islamic stocks

We estimate momentum profits for a large portfolio of Islamic stocks, control for stock characteristics and the state-of-the-market, explore seasonal patterns, and examine the determinants of profits. We discover ample evidence that momentum strategies work for Islamic stocks, but are stock characteristic-dependent, that up and down phases of the market offer different profits, and that there is a January effect on profits. We also find that the market risk factors - namely, excess market returns, value, size, and betting-against-beta factors - and macroeconomic risk factors do explain profits. We conclude that the profitability of Islamic stocks is merely compensation for risks and is not due to mispricing.

Credit quality implied momentum profits for Islamic stocks

Using a sample of Asia-Pacific Islamic stocks we show that momentum profits exist regardless of the credit quality of stocks. A portfolio of low credit quality stocks earns 4.68% per annum more than a portfolio of high credit quality stocks. Market risk factors explain all momentum profits, suggesting that profits are compensation for risks. Post-holding period analysis suggests strong evidence of return reversal, consistent with the behavioral hypothesis. Our main results are also robust to sub-samples of data characterized by the recent global financial crisis and to Islamic and non-Islamic based market risk factors.

Is momentum trading profitable from Shari'ah compliant stocks?

This research offers fresh evidence supporting the pervasiveness of the momentum effect. Two decades after the momentum profitability firstly documented by Jegadeesh and Titman (1993), yet little research has been specifically devised for the momentum profitability on Shari'ah compliant stocks. We assess the momentum profitability over the Shari'ah compliant stocks in a Malaysian setting. We find evidence of strong return persistence as far as toward four-year holding period. Interestingly, no significant momentum returns are found among the conventional stocks. Upon further exploration we find neither an industry-driven momentum effect nor the small size firms can account for the momentum returns. Using return persistency formation criteria, we further find that underreaction seems to well fit in explaining this unique long lasting momentum profitability.
