(5) 1. Introduction: Stock index futures markets have two important functions. First, they provide forecasts of stock index, and second, they help to transfer stock index returns risk. Rationally, the returns on stock index and stock index futures contracts should be contemporaneously correlated in efficient markets. Although futures returns tend to lead stocks returns, the effect is not completely unidirectional, with lagged stock index returns having a mild positive predictive impact on futures returns (e.g., Stoll and Whaley, 1990).. 治 政 There are papers which considered information大 transmission between stock 立 index and index futures markets. Bhar (2001) examined Australian equity index ‧ 國. 學. futures and spot prices with EGARCH model. The result of this study shows that. ‧. information transmission from futures to spot and reverse case both exist. Meneu and. sit. y. Nat. Torro (2003) computed the Asymmetric Volatility Impulse Response Function for the. io. er. Spanish stock index and its futures contract. The Volatility Impulse Response. al. Function (VIRF) for asymmetric multivariate GARCH structures is extending from. n. iv n C Lin (1997) findings for symmetric GARCH The empirical results indicate h e n gmodels. chi U that the spot-futures variance system is more sensitive to negative than positive. shocks, and that spot volatility shocks have much more impact on futures volatility than vice versa. Fu and Qing (2006) examined the price discovery process and volatility spillovers in Chinese spot-futures markets through Johansen cointegration and bivariate EGARCH model. The empirical results indicated that the models provided evidence supporting the volatility spillovers from futures to spot were more significant than the other way round.. 1.
(6) Given the above background, I am interested in the relationship between Taiwan spot and futures markets. In the following section, I will us a generalized vector autoregressive (generalized VAR) model, developed by Diebold and Yilmaz (2009), to examine daily return and volatility spillovers. Sims (1980) introduced VAR variance decompositions, which record how much of the H-step-ahead forecast error variance of some variable, i, is due to innovations in another variable, j.1 Diebold and Yilmaz (2009) introduce a method used to measure spillovers in returns and return volatilities based on forecast error variance decompositions from vector autoregressive model. But the framework has an ordering problem since it relies on. variance decompositions are invariant to variable ordering.. 學. ‧ 國. 治 政 大 solve this problem by Cholesky-factor identification of VARs. Diebold and Yilmaz 立 constructing a generalized vector autoregressive framework in which forecast-error ‧. The empirical results of this study indicate that directional return/volatility. y.

Ch. i Un. v. negative net spillovers. However, in rolling sample analysis, we can still observe net. engchi. return spillovers from TE index to others and net return spillovers from TF index to others. The above empirical findings reveal that, in Taiwan, the future markets play a dominant role in the return and volatility spillover to spot markets but we could not ignore return spillovers from spot to futures.. This paper proceeds as follows. Section 2 discusses the methodological. 1. Assume that yt is a covariance stationary time series. Let. yˆ.

Generalized Spillover Definition and Measurement Diebold and Yilmaz’s framework is progressed by measuring directional spillovers in a generalized VAR model that eliminates the possible ordering problem. Consider a covariance stationary N-variable VAR(p), p. 政 治 大. x t i x i 1 t. 立. i 1. ‧. ‧ 國. 學. ,where ~ (0, ) . The moving average is,. . x t Ai t i i 0. i. n.

Estimates of Equity Index Return and Volatility Spillovers Across Taiwan Spot and Futures Markets I use the framework to measure returns and volatility spillovers among six key Taiwan stock index classes: Taiwan Stock Exchange Capitalization Weighted Stock Index (TX), Taiwan Stock Exchange Electronic Sector Index (TE), Taiwan Stock Exchange Finance Sector Index (TF), Future index of TAIEX (FITX), Future index of TE (FITE) and Future index of TF (FITF). 5.
(10) The underlying data are daily closing price of stock and future market indexes, January 2001~March 2010, taken from TEJ Database. I calculate daily returns as the change in log price, day to day. I provide a variety of descriptive statistics for returns in Table 1 and plot the six indices’ returns in Figure 1. We can see that the Finance Sector Index and it’s future has relative lower mean returns than the other indices. All the six indices have dramatically returns fluctuation around 2002~2004 and 2007~2009.. Following Alizadeh, Brandt and Diebold (2002), we estimate daily variance. 政 治 大. using daily high and low prices. For market i on day t, σ =0.361 ln P. 學. Because σ. 立. ,. is the highest price in market i on day t, and P is the daily lowest price.. ‧ 國. where P. − ln P. is an estimator of the daily variance, the corresponding estimate of the. ‧. annualized daily percent standard deviation (volatility) is σ =100 365 × σ. . The. Nat. sit. y. formula here using 365 days instead of 240 days (actually trading days in a year) is. n. al. er. io. the same with Diebold and Yilmaz’s approach and will not affect our outcome. I. i Un. v. provide descriptive statistics for volatilities in Table 2 and give the plot in Figure 2.. Ch. engchi. We find that FITF has the highest mean and standard deviation. It means that FITF has greater daily volatility in the past 10 years, especially from 2007 to 2009.. [Insert Table 1, Table 2, Figure 1and Figure 2 Here] 3.1 Full-sample analysis. Here I provide a full-sample analysis of Taiwan six key index classes return and volatility spillovers. I begin by characterizing return and volatility spillovers over 6.
(11) the entire sample, January 2001~March 2010. Later I will track time variation in spillovers via rolling sample estimation. Before I test for generalized VAR model, it is necessary to do the unit root tests of each variable. The result from Augmented Dickey-Fuller Unit Root Test shows that all the variables are stationary at their levels. In the following empirical work, I use first-order generalized VAR with 10-step-ahead forecasts.2 I report Spillover Indexes for returns and volatility in Tables 3 and 4, respectively.. [Insert Table 3 and Table 4 Here]. The xy. 政 治 大 entry in the 立spillover table is the estimated contribution to the. ‧ 國. 學. forecast error variance of index x coming from shocks to index y. The off-diagonal column sums represent directional to others and the off-diagonal row sums represent. ‧. directional from others. The total spillover rate, which appears in the lower right. Nat. sit. y. corner of the table, is approximately the off-diagonal column (or row) sums relative to. n. al. er. io. the column (or row) sums including diagonals. The spillover table shows a “to and. i Un. from” two-way decomposition of the total spillover effect.. Ch. engchi. v. In Table 3, we can see that gross directional returns spillovers to others from the future markets are relatively large (especially FITE), at 82.06 percent, 94.27 percent and 88.10 percent, respectively. From the “directional from others” column, gross directional return spillovers from others to TX is relatively large, at 85.99 percent. In Table 4, we can also see that gross directional volatility spillovers to others from the future markets are relatively large (especially FITF), at 84.60 percent, 102.03. 2. The method is the same with Diebold and Yilmaz’s approach and it will not affect our key conclusions. 7.
(12) percent and 105.28 percent, respectively. The spillovers here exceed 100 percent is mainly because we standardize the formulae for row sums (directional from others) and the sum of “directional to others” column must equal the sum of “directional from others” column. From the “directional from others” column, gross directional volatility spillovers from others to TX is relatively large, at 87.30 percent. Considering net directional returns and volatility spillovers, future markets have positive and spot markets have negative net spillovers. As for net directional return spillovers, the largest SPT and SPF are to others from FITE and from others to TX. As for net directional volatility spillovers, the largest SPT and SPF are to others from. 治 政 大 in both returns and FITF and from others to TX. The total spillovers are important 立 volatilities since almost 75% of forecast error variance comes from spillovers, both ‧ 國. 學. for returns (78%) and volatilities (75%).. ‧. sit. y. Nat. Here I use the nonparametric bootstrapping method (Efron, 1979) to conduct. io. er. the significant test. By simulating 1000 replications, I calculate the 95% confidence. al. interval and check the p-value of the directional spillover 10-ahead forecast. In table 3,. n. iv n C SPF and SPT are all statistically significant. NET spillovers, except FITX h e n gConsidering chi U is insignificant, all others are statistically significant. In Table 4, SPF, SPT and SPN are all statistically significant.. 3.2 rolling-sample analysis The full-sample Spillover Tables and Spillover Indexes provide a useful summary of average behavior, but they are likely to miss the potentially cyclical movements in spillovers. To address this issue, I estimate the models using 100 days 8.
(13) rolling samples. I present the Spillover Plot for returns and volatility in Figure 3. [Insert Figure 3 Here] The total return spillover plot usually fluctuates between seventy-five and eighty percent, occasionally falling below seventy-five percent. The total volatility spillover plot usually fluctuates between seventy and eighty percent, occasionally falling below seventy percent. The total volatility spillover plot (TVS) and the total return spillover plot (TRS) display similar trend pattern, but TVS ranges widely than TRS. At the beginning of 2007, the total return spillovers and the total volatility. 政 治 大. spillovers both dropped to around sixty-five percent (the relative lower rate in the. 立. decade). Soon after the falling, they climbed up dramatically to about eighty percent. ‧ 國. 學. (the relative higher rate in the decade) and then the global financial crisis occurred, lasting from 2007~2009. During this period, the total return spillovers maintained. ‧. around eighty percent. The total volatility spillovers also came to the highest level. y. Nat. n. er. io. al. sit. (over seventy-five percent).. 3.3 rolling-sample directional spillover. Ch. engchi. i Un. v. After discussing the total dynamic spillover plot, we now also want to estimate the row and column dynamically. We call these directional spillover plots. In Figure 4, I present the directional return and volatility spillovers from the six stock index classes. The fluctuation of TX, TE and TF is about ten percent, twenty percent and thirty percent. The fluctuation of FITX, FITE and FITF is about twenty percent, forty percent and sixty percent. The plots show that the directional return and volatility spillover lines of all six indices vary obviously over time and FITF fluctuates larger than other indices. In Figure 5, I present the directional return and volatility spillovers 9.
(14) to the six stock index classes. Comparing with the directional spillovers from others, the spillovers to others vary greatly over time. We can find the Finance Sector Indices (TF and FITF) have an increasing trend. This can be easily figured out because there was a global financial crisis during 2007~2009 and MOU agenda between Taiwan and Mainland China governments during 2009~2010. [Insert Figure 4 and Figure 5 Here] Calculating difference between the “Contribution from” column sum and the “Contribution to” row sum, we can derive the net directional spillovers moving. 政 治 大. pattern. Figure 6 shows the net directional spillover plot. Overall, there has been very. 立. little net return and volatility transmission from the spot markets. This result is quite. ‧ 國. 學. easy to understand owing to stock index futures having the function on forecasting stock index and helping to transfer stock index returns risk. But we can still observe. ‧. net return spillovers from TE index to others reach about twenty percent during. y. Nat. io. sit. 2005~mid 2006. Net return spillovers from TF index to others reach about fifty. n. al. er. percent during 2009 and the first half of 2004. Further, net return and volatility. Ch. i Un. v. spillovers from FITE and FITF appear the most consistently positive and large.. engchi. Although FITX is a future index, it is not an important net transmitter of return and volatility. This is because FITE and FITF also influence FITX a lot.3 Following the financial market turmoil associating with the subprime mortgage market that started in July-August, 2007, net return spillover plot of FITF had an upward trend, and net return spillover plot of FITE had a downward trend. We can say that during the global financial crisis 2007~2009, net return and volatility spillovers from FITF affected mostly the other index. 3. The two major components of Taiwan stock market are Electronic sector and Finance sector. 10.
(15) [Insert Figure 6 Here]. 4. Conclusion In this paper I examine daily return and volatility spillovers of Taiwan spot and futures stock indices by using a generalized vector autoregressive model where forecast-error variance decompositions are invariant to variable ordering. I also calculate both gross and net directional return/volatility spillovers and look further in dynamic analysis. The result of empirical analysis can be summarized as follows: The clear channels of directional return/volatility spillovers to others are from FITE and. 治 政 大than trading volume of FITE FITF. Although trading volume of FITX are much larger 立 and FITF in Taiwan futures market, FITE and FITF are mainly traded by Institutional ‧ 國. 學. investors such as Securities Investment Trust, Foreign investors and Securities. ‧. Dealers. These Institutional investors are more professional and have more market. sit. y. Nat. information. That is why the return and volatility spillovers from FITE and FITF to. io. er. other indices are relatively large. Considering net directional returns and volatility. al. spillovers, future markets have positive and spot markets have negative net spillovers.. n. iv n C However, in rolling sample analysis, observe net return spillovers from h we e ncangstill chi U TE index to others reach about twenty percent during 2005~mid 2006. Net return. spillovers from TF index to others reach about fifty percent during 2009 and the first half of 2004. The above empirical findings reveal that the future markets play a dominant role in the return and volatility spillover to spot markets but we could not ignore return spillovers from spot to futures. Since the occurrence of the global financial crisis from 2007 and the MOU issue negotiated between Taiwan and Mainland China governments during 2009~2010, the Finance sector has a greater influence over Taiwan stock markets than Electronic sector in recent years. 11.
