The purpose of the thesis aims to investigate pair trading strategies which are frequently used by hedge funds adopting non-directional strategies. It is also our intention to develop a set of streamlined operational guidelines for pair trading strategy to be implemented in the Taiwan securities markets.
Daily closing prices of listed stocks are used. The database is compiled by Taiwan Economic Journal, covering companies listed on the Taiwan Stock Exchange and the GreiTai Market in Taiwan. The company-pairs are selected from firms listed on the same market, conducting business in the same product field, and with sample correlation coefficient higher than 0.7. We choose 10 sample company-pairs covering 20 listed companies.
The trading strategies mix both divergence and convergence rules. For the former, when the price ratio of the pair exceeds the moving average price ratio plus (minus) 0.3 standard deviation, we buy the strong and short the weak to anticipate the price ratio trend continues. For the latter, when the price ratio goes beyond the moving average price ratio plus (minus) 1.7 standard deviations, we buy the weak and short the strong, anticipating the price ratio to go back to normal. The exit rules are based on absolute dollar profit, absolute dollar loss, and prolonged position period.
The research results show that the pair trading strategies are not risk-free. Risk arises
when the price ratio trend runs adversely than as expected. To control the risk, our
challenges lie in fine tuning the entry and exit rules. With larger sample size and more
in-depth investigation, we expect that the profit/loss ratio of the stragtegy can be
improved. Then the pair trading strategy will become a good alternative for
conservative individual investors seeking low risk investment opportunities to
participate in the securities markets in Taiwan.

Essays on trading strategies and long memoryRambaccussing, Dooruj January 2012 (has links)
Present value based asset pricing models are explored empirically in this thesis. Three contributions are made. First, it is shown that a market timing strategy may be implemented in an excessively volatile market such as the S&P500. The main premise of the strategy is that asset prices may revert to the present value over time. The present value is computed in real-time where the present value variables (future dividends, dividend growth and the discount factor) are forecast from simple models. The strategy works well for monthly data and when dividends are forecast from autoregressive models. The performance of the strategy relies on how discount rates are empirically defined. When discount rates are defined by the rolling and recursive historic average of realized returns, the strategy performs well. The discount rate and dividend growth can also be derived using a structural approach. Using the Campbell and Shiller log-linearized present value equation, and assuming that expected and realized dividend growth are unit related, a state space model is constructed linking the price-dividend ratio to expected returns and expected dividend growth. The model parameters are estimated from the data and, are used to derive the filtered expected returns and expected dividend growth series. The present value is computed using the filtered series. The trading rule tends to perform worse in this case. Discount rates are again found to be the major determinant of its success. Although the structural approach offers a time series of discount rates which is less volatile, it is on average higher than that of the historical mean model. The filtered expected returns is a potential predictor of realized returns. The predictive performance of expected returns is compared to that of the price-dividend ratio. It is found that expected returns is not superior to the price-dividend ratio in forecasting returns both in-sample and out-of-sample. The predictive regression included both simple Ordinary Least Squares and Vector Autoregressions. The second contribution of this thesis is the modeling of expected returns using autoregressive fractionally integrated processes. According to the work of Granger and Joyeux(1980), aggregated series which are derived from utility maximization problems follow a Beta distribution. In the time series literature, it implies that the series may have a fractional order (I(d)). Autoregressive fractionally models may have better appeal than models which explicitly posit unit roots or no unit roots. Two models are presented. The first model, which incorporates an ARFIMA(p,d,q) within the present value through the state equations, is found to be highly unstable. Small sample size may be a reason for this finding. The second model involves predicting dividend growth from simple OLS models, and sequentially netting expected returns from the present value model. Based on the previous finding that expected returns may be a long memory process, the third contribution of this thesis derives a test of long memory based on the asymptotic properties of the variance of aggregated series in the context of the Geweke Porter-Hudak (1982) semiparametric estimator. The test makes use of the fact that pure long memory process will have the same autocorrelation across observations if the observations are drawn at repeated intervals to make a new series. The test is implemented using the Sieve-AR bootstrap which accommodates long range dependence in stochastic processes. The test is relatively powerful against both linear and nonlinear specifications in large samples.

The pricing or mispricing of earnings quality in AustraliaWong, Leon Keat Leong, Accounting, Australian School of Business, UNSW January 2009 (has links)
This thesis investigates the pricing (or mispricing) of earnings quality in Australia. It investigates whether information in earnings quality is used by investors in valuing firms, evidenced by an association between earnings quality and the cost of equity. In the alternate form, the question may be posed as whether earnings quality is mispriced by investors such that there may be opportunities to earn abnormal profits from trading strategies based on earnings quality. Ten earnings quality constructs are studied: total accruals, unexpected accruals, cash-to-profit, accrual quality, persistence, predictability, smoothness, relevance, conservatism and timeliness. In the cost of equity pricing tests, when earnings quality is proxied using one construct (accrual quality), it is found to be associated with the cost of equity. However, when the additional nine constructs are included in the regression models, accrual quality loses statistical significance. Various other constructs are found to be associated with the cost of equity depending on the choice of the cost of equity proxy. In the trading strategy tests, there is some initial evidence of trading strategy opportunities for firms with high quality earnings. However, after deleting outlier observations with annual buy-and-hold returns of greater than 200% the potential for earning abnormal returns from a hedge portfolio strategy disappears. The existence of Australian evidence on the accruals anomaly provides a convenient basis to validate the results of the earnings quality trading strategy tests. Although no clear evidence on the accruals anomaly is found, results are obtained which appear to be consistent with prior Australian evidence of the accruals anomaly, depending on the research design choices made. Overall, the evidence on whether earnings quality is priced or mispriced in Australia is best viewed as inconclusive. It highlights the importance of conducting thorough robustness tests and suggests a need for caution by researchers in making inferences from a narrow set of earnings quality constructs and research design specifications.

Exploiting Market Reactions to Dividend Cuts : Contrarian Trading Strategies in a Short Investment Horizon - Evidence from the Swedish Stock MarketMagnusson, Jacob Magnusson, Karlsson, N. E. Ludvig January 2016 (has links)
This paper investigates the impact of dividend reduction announcements on the returns to stocks listed on the Stockholm Stock Exchange. We perform an event study on dividend cutting firms between 2002-2016 to determine if contrarian trading on the basis of negative dividend announcement yields abnormal returns. We evaluate the immediate market reaction during a three-day event window surrounding dividend announcements. Thereafter we test a contrarian trading strategy by examining abnormal returns during a holding period up to twenty days following the initial event. We evaluate the results in reference to previous literature on post earnings (dividend) announcement drift and contrarian investment strategies. The findings suggest that the initial market reaction to dividend cuts is negative, but that the abnormal returns to buying stock following dividend reduction announcements are negligible. Furthermore, we argue that there might be means of increasing these returns by supplementary analysis of firm specifics.

The research of momentum trading strategies in Taiwan stock mocketLin, Chiu-hui 27 July 2007 (has links)
This thesis studies the momentum trading strategies, in which investors buy stocks that performed well in the past and sell stocks that underperformed over the same peiord of time. We examine the momentum strategies from January of 1995 to September of 2006. This thesis has two purposes. First, do the momentum trading strategies generate positive abnormal returns ? Second, do the momentum trading strategies generate positive abnormal returns even after we consider the limits of short-selling stocks ? The results indicate that the momentum trading strategies generate significant positive returns. Furthermore, the momentum trading strategies still offer positive abnormal returns even after the limits of short-selling shares are taken into account, although the magnitude of positive abnormal returns decreases.

Exchange rate forecasting and the performance of currency portfoliosCrespo Cuaresma, Jesus, Fortin, Ines, Hlouskova, Jaroslava 08 1900 (has links) (PDF)
We examine the potential gains of using exchange rate forecast models and forecast combination methods in the management of currency portfolios for three exchange rates: the euro versus the US dollar, the British pound, and the Japanese yen. We use a battery of econometric specifications to evaluate whether optimal currency portfolios implied by trading strategies based on exchange rate forecasts outperform single currencies and the equally weighted portfolio. We assess the differences in profitability of optimal currency portfolios for different types of investor preferences, two trading strategies, mean squared error-based composite forecasts, and different forecast horizons. Our results indicate that there are clear benefits of integrating exchange rate forecasts from state-of-the-art econometric models in currency portfolios. These benefits vary across investor preferences and prediction horizons but are rather similar across trading strategies.

Momentum strategies : Empirical evidence from the Swedish stock marketTsilfidis, Georgios, Nikolova, Anita January 2014 (has links)
The study is based on the study of Jegadeesh and Titman (1993, 2001) which found evidence of succesfull trading strategies which yielded significant positive abnormal returns by exploiting a momentum pattern in stock prices. The purpose of this study is to contribute with empirical results to the discussions of efficient markets, momentum effects and behavioral finance by providing evidence from the Swedish stock market between the years 1998 and 2013. The conclusion is that there exists a Momentum Effect on the Swedish stock market. The utilization of momentum strategies yields significant positive abnormal returns. The Efficient Market Hypothesis is a model which might hold in the long-term, but shows limitations in the short-term. The implications of the results of this study are that short-term investor behavior and momentum profits might be partially explained by behavioral finance models but the origin of the momentum profits need to be further evaluated.
