Settlement procedures and stock market efficiency

This study examines why most derivatives markets that settle on the day following expiration choose the opening rather than the closing price as the final settlement price (FSP), whereas most markets that settle on the expiration day select an average rather than a single price as the FSP. Four exogenous changes in the Taiwan Futures Exchange settlement procedures provide an experimental basis for studying the settlement procedures’ impact on underlying assets. Greatest market efficiency is observed when the FSP is determined by a single rather than an average price and hypothesize that manipulation is prevented at the expense of market quality.     

The intra‐day price discovery process between the Singapore Exchange and Taiwan Futures Exchange

This paper focuses on the increasing competition between exchanges for listing similar index futures contracts and the impact this has on information dissemination between various markets. Specifically, using both the Hasbrouck and Gonzalo–Granger methodologies for extracting the information content held in each market, a comparison of information efficiencies between the Singapore Exchange and the Taiwan Futures Exchange is examined for Taiwan Index Futures listed in both markets. The results show not only a common stochastic trend between index futures and their underlying indices, but also provide strong evidence to suggest price discovery primarily originates from the Singapore futures market. There are direct implications of this result for both financial exchanges and traders—in particular, that traders realize price determination can arise from both futures markets, and the need for exchanges to maintain a reputation as an information center for these similarly traded financial instruments. © 2002 John Wiley & Sons, Inc.

Trading activity in stock index futures markets: The evidence of emerging markets

This study investigates the trading activity of the Taiwan Futures Exchange (TAIFEX) and Singapore Exchange Derivatives Trading Limited (SGX‐DT) Taiwan Stock Index Futures markets by analyzing the intraday patterns of volume and volatility. In addition, the market closure theory, which may explain such patterns, is examined. Overall, the trading pattern appears to be U‐shaped for the TAIFEX futures and U+W‐shaped for the SGX‐DT. For the SGX‐DT futures, volatility follows the same pattern as that of the number of price changes. For the TAIFEX futures, however, after the peak at the close of the spot market, the volatility in the TAIFEX futures drops consistently until the end of the day while volatility in the SGX‐DT still reaches a smaller peak at the close of the futures market. In addition, a visual inspection of the intraday patterns of these two markets shows that the market closure theory can effectively explain the intraday patterns of these two markets. The empirical results support the market closure theory in that liquidity demand from traders rebalancing their portfolios before and after market closures creates larger volume and volatility at both the open and close. © 2002 Wiley Periodicals, Inc.

The relative efficiencies of price execution between the Singapore Exchange and the Taiwan Futures Exchange

Both the Singapore Exchange (SGX) and the Taiwan Futures Exchange (TAIFEX) offer future contracts based on Taiwan's stock‐market indices. TAIFEX reduced the transaction tax from 5 basis points to 2.5 basis points on May 1, 2000. Hence, empirical tests are performed on the differences in trading costs and information transmissions between SGX and TAIFEX for the sample periods both before and after the tax reduction. It is shown that the reduction in the transaction tax greatly improves the efficiencies of price execution. Due to the structural differences between these two markets, the trading costs and speed of information transmissions also are different. The results also provide implications for the relative efficiencies of different market structures. © 2002 John Wiley & Sons, Inc. Jrl Fut Mark 22:173–196, 2002     

The components of bid‐ask spread and their determinants: TAIFEX versus SGX‐DT

This paper compares the intraday components of bid‐ask spread in Taiwan stock index futures traded on Taiwan Futures Exchange (TAIFEX) and Singapore Exchange Derivatives Trading Limited (SGX‐DT). Variables that determine the components of spread are also examined. SGX‐DT uses a floor trading system while TAIFEX uses an electronic call system. This study finds that both information asymmetry and order processing cost components exhibit U‐shaped patterns in the two markets, in contrast to previous findings for U.S. equity markets. Moreover, the information asymmetry components are lower in the TAIFEX relative to the SGX‐DT futures, suggesting that the continuous open outcry markets are more vulnerable to information asymmetry than the electronic call markets. The regression results show that volatility and information are the major determinants of the components while number of trades is not the major determinant of the order processing and information asymmetry components for both markets. © 2004 Wiley Periodicals, Inc.

Why and how do foreign institutional investors outperform domestic investors in futures trading: Evidence from Taiwan

A unique data set containing all transactions from the Taiwan Futures Exchange allows us to dissect the long-lasting outperformance of foreign institutional investors in this emerging market. We show that foreign institutional investors comprehensively outperform domestic investors in trade directions, submission types, trading counterparties, order sizes, and order aggressiveness. Although submitting passive orders increases the trading profits of each investor group significantly, particularly for foreign institutions, the most passive domestic trades still lose to the most aggressive foreign institutional trades. We suggest that information advantage plays a more important role than order submission strategy in foreign institutional investors’ superior performance.     

The impact of electronic trading on bid‐ask spreads: Evidence from futures markets in Hong Kong,London, and Sydney

During 1999 and 2000, three major futures exchanges transferred trading in stock index futures from open outcry to electronic markets: the London International Financial Futures and Options Exchange (LIFFE); the Sydney Futures Exchange (SFE); and the Hong Kong Futures Exchange (HKFE). These changes provide unique natural experiments to compare relative bid‐ask spreads of open outcry vs. electronically traded markets. This paper provides evidence of a decrease in bid‐ask spreads following the introduction of electronic trading, after controlling for changes in price volatility and trading volume. This provides support for the proposition that electronic trading can facilitate higher levels of liquidity and lower transaction costs relative to floor traded markets. However, bid‐ask spreads are more sensitive to price volatility in electronically traded markets, suggesting that the performance of electronic trading systems deteriorates during periods of information arrival. © 2004 Wiley Periodicals, Inc.

Market microstructure effects on volatility at the TAIFEX

This study examines whether changes in the frequency of market clearing or changes in trading hours on competing exchanges that use different auction systems affect the volatility of futures prices. In particular, this study exploits a natural experiment in the frequency of market clearing of stock index futures contracts traded on the Taiwan Futures Exchange (TAIFEX) to assess whether successive increases in the frequency of market clearing are associated with changes in the volatility of futures prices. The impact of changes in the trading hours on the TAIFEX and on the competing Singapore Exchange (SGX) where a similar Taiwanese stock index futures contract trades under a continuous auction market regime is also examined. The evidence for the impact of an increase in the frequency of market clearing on volatility is mixed. However, the introduction of simultaneous opening times for the TAIFEX (which batches orders at the open) and the SGX (which does not) is associated with a significant reduction in the volatility in SGX Taiwanese stock index futures prices. © 2007 Wiley Periodicals, Inc.

Regulatory changes and information competition: The case of Taiwan index futures

This article examines the cross‐border competition in price discovery between the Taiwan Futures Exchange (TAIFEX) and the Singapore Exchange Derivatives Trading (SGX). We focused on the impact of market reforms on the information leadership of similar contracts traded on the two exchanges. Utilizing synchronized transaction data, it was found that reducing the futures transferring tax was the only policy change that enhanced TAIFEX's information role. Evidence supported the trading‐cost hypothesis that a lower transaction cost is associated with better price discovery. A brief linkage between trading volume and price discovery was found when data were broken down into subperiods according to the relative volume of TAIFEX and SGX. Evidence suggested that the SGX's information advantage reported in previous research had diminished as the rival market progressed. It also indicated that exchanges seeking to improve information efficiency should adopt policies that will reduce transaction costs or increase trading volume. © 2004 Wiley Periodicals, Inc.

Strategic order splitting,order choice,and aggressiveness: Evidence from the Taiwan futures exchange

We investigate the strategic order‐splitting behavior and order aggressiveness of different types of traders using a unique dataset on the Taiwan Futures Exchange. By examining the trades and orders for each and every account, we find that, as compared with domestic institutional traders and individual traders, foreign institutional traders and futures proprietary firms are more likely to split their orders and it appears that the price adjustments after their trades are permanent. Foreign institutional traders and futures proprietary firms seem to be better informed, with their orders apparently being split so as to reveal their information on a gradual basis. Furthermore, we find that foreign institutional traders and futures proprietary firms use fewer market orders, choosing instead to submit aggressive limit orders, possibly due to their desire to make the most of their information advantage. © 2009 Wiley Periodicals, Inc.
