Prior research into the cost of trading on the Australian Stock Exchange has identified brokerage fees and the bid-ask spread as significant elements of total transaction costs. While an enormous volume of research has examined the determinants of spreads in US markets, no work has so far addressed the issue for the Australian market-place. Given the importance of spreads as a transaction cost, this work redresses this imbalance and at the same time provides evidence on whether alternative market structures underlying different exchanges give rise to differences in the determinants of spreads. Using prior US research as our benchmark, our results suggest that notwithstanding microstructure differences between the Australian and US exchanges, there are three fundamental determinants of spreads that transcend differences in the market-places. These are the level of trading activity, price volatility and stock price levels. Together these three factors account for up to 94% of the total cross-sectional variation in percentage bid ask spreads on the ASX.  相似文献

We use transaction data for Toronto Stock Exchange (TSE) listed stocks to examine the impact on trading costs of the decision to interlist on a US exchange. We measure trading costs using both ‘posted’ bid-ask spreads and ‘effective’ bid-ask spreads that measure actual transaction prices relative to standing bid-ask quotes. After controlling for price level, trade size and trading volume effects, we find that overall posted and effective spreads in the domestic (TSE) market decrease subsequent to the interlisting. However, the decrease in trading costs is concentrated in those TSE stocks that experience a significant shift of total trading volume (TSE and US) to the US exchange after listing. We interpret this result in the context of theories of multimarket trading as a competitive response by TSE market makers to the additional presence of US market makers.  相似文献

This paper develops a model of exchange rate bid-ask spreads which is used to examine the relationship between exchange rate risk and volatility and to measure transactions costs. The empirical results indicate that market-makers judge the probability of exchange rate changes based on both recent and long-term volatility and that the second moment alone is not a complete measure of volatility. While a proxy for trading volume does not have the expected relationship with spreads, weekend and holiday effects conform to theory. Transactions costs vary over time and seem responsive to the imposition of exchange controls.  相似文献

We investigate the effect of option market transaction costs (a form of market imperfection) on the ability of option implied volatility-based measures to predict future stock returns and volatility around quarterly earnings announcements. We find that the predictability is significantly stronger for firms with lower option relative bid-ask spreads. The effect is more pronounced around positive rather than negative earnings news. We find no significant effect of option transaction costs around randomly chosen dates when there is no clustering of major information events. Trading strategies based on option market predictors and transaction costs earn monthly abnormal returns of 1.39% to 1.91%.  相似文献

In this paper I show that the co-movements between bid-ask spreads of equities and credit default swaps vary over time and increase over crisis periods. The co-movements are strongly related to systematic risk factors and to the theoretical debt-to-equity hedge ratio. I document that hedging and asymmetric information, besides higher funding costs and market volatility risk, are driving factors of the commonality and are significantly priced in CDS bid-ask spreads.  相似文献

We investigate how new information impacts quote clustering in the bond market. We find that clustering, along with quote activity, price volatility and bid-ask spreads, increases sharply in the minutes following releases of macroeconomic news. Each returns to near-normal levels within the hour. Effects are strongest for more liquid on-the-run notes and for the announcements typically associated with substantial information flow. The strong positive comovement of clustering, quote activity, price volatility, and bid-ask spreads supports the conclusion that innovations of these variables are endogenous to the arrival and incorporation of information into prices.  相似文献

Market making with discrete prices   总被引:3,自引:0,他引:3  
Exchange-mandated discrete pricing restrictions create a wedgebetween the underlying equilibrium price and the observed price.This wedge permits a competitive market maker to realize economicprofits that could help recoup fixed costs. The optimal ticksize that maximizes the expected profits of the market makercan equal to $1/8 for reasonable parameter values. The optimaltick size is decreasing in the degree of adverse selection.Discreteness per se can cause time-varying bid-ask spreads,asymmetric commissions, and market breakdowns. Discreteness,which imposes additional transaction costs, reduces the valueof private information. Liquidity traders can benefit undercertain conditions.  相似文献

The effects of large transactions on OTC security dealers' bid-ask spreads are analyzed for stocks with different price levels. Because overhead expenses vary little with the value of transactions, economies of scale exist for dealers in higher-priced stocks. Thus, percentage bid-ask spreads decline with the price level of the stock. However, larger transactions entail larger order-clearing and inventory-adjustment costs. These costs may be particularly burdensome for smaller dealers with limited purchasing powers and abilities to diversify inexpensively. Consequently, smaller dealers charge higher spreads for trading high-priced stocks.  相似文献

Previous literature has suggested that automated exchanges such as the Deutsche Terminborse (DTB) may be less liquid than their open-outcry counterparts such as the London International Financial Futures Exchange (LIFFE), although evidence provided on this issue has been mixed. This paper provides new evidence on the relative magnitudes of bid-ask spreads in the Bund contract traded on the DTB and LIFFE using intraday data from a period in which each exchanges share of total Bund trading was closer than previous research. The findings suggest that quoted bid-ask spreads are wider on the LIFFE than the DTB, even after controlling for their determinants. Furthermore, bid-ask spreads on the DTB increase more rapidly as price volatility increases relative to the LIFFE. Overall, this evidence implies that while automated exchanges are capable of providing more liquidity than floor traded exchanges, the relative performance of automated exchanges deteriorates during periods of higher volatility.  相似文献

The behavior of quote arrivals and bid-ask spreads is examined for continuously recorded deutsche mark-dollar exchange rate data over time, across locations, and by market participants. A pattern in the intraday spread and intensity of market activity over time is uncovered and related to theories of trading patterns. Models for the conditional mean and variance of returns and bid-ask spreads indicate volatility clustering at high frequencies. The proposition that trading intensity has an independent effect on returns volatility is rejected, but holds for spread volatility. Conditional returns volatility is increasing in the size of the spread.  相似文献
