“…While the dynamics between HSI index and futures returns have been documented (Tang, Mak, and Choi 1992;Chiang and Fong 2001;Jiang, Fung, and Cheng 2001;Draper and Fung 2003;Chan, Chan, and Cheng 2004;Chiang and Wang 2008), including the potential arbitrage associated with mispricing (Cheng, Fung, and Tse 2005;Zhang and Lai 2006;Wang 2008), the investigation of the non-linear dynamics between the Hang Seng stock index and futures returns remains relatively unexplored. Consequently, this investigation adds to a developing literature that applies more complex modelling techniques (Eling and Toplek, 2009), such as Fractionally Integrated Error Correction models (Rajaguru and Pattnayak 2007), Exponential Generalised Autoregressive Heteroskedastic models (Butler and Okada 2008), Markov switching models (Okimoto 2008), or wavelet analysis (In and Kim 2006) Martens, Kofman and Vorst (1998) utilises a threshold error-correction model to investigate the complex dynamics between intraday Standard & Poors 500 futures and index returns, our main objective lies in the application of a Threshold AutoRegressive (TAR) model to the Hong Kong stock and futures markets.…”
