Retail Investors and the Trading of Treasury Securities

I analyze implicit transaction costs of trading government debt securities on the Spanish stock exchanges (SE) electronic trading system. The SE’s multilateral system is used mainly as an outlet for retail investors to liquidate Treasury accounts positions before maturity. I compare identical Treasury security trades on the same day in two different markets: the SE and the interdealer market. By analyzing these yield spreads I learn more about the behavior of the markdowns included in the retail prices from the institutional prices. I find evidence that these yield premia depend on traditional features to explain wholesale market liquidity premia.

The ex-dividend day stock price anomaly: evidence from the Greek stock market

This paper examines the ex-dividend stock price and trading volume behavior in the Greek stock market for the period 2000–2004. We use both standard event-study methodology and cross-sectional regression analysis in assessing the ex-dividend stock price anomaly. We find that stock prices drop less than the dividend amount. By examining abnormal returns as well as abnormal trading volume around the ex-dividend day, we find strong evidence of short-term trading, which is consistent with the presence of dividend-capturing activities around the ex-dividend day. The results from the cross-sectional regression analysis confirm that the short-term trading hypothesis explains the ex-dividend day stock price anomaly in Greece.

School Quality, House Prices and Liquidity

This paper develops an empirical framework for taking into account the effects of endogenous liquidity on price capitalization estimates. Changes in school attendance zones in the East Baton Rouge Parish public school district provide a natural experiment for studying how changes in school characteristics affect house prices and liquidity. House price and selling time, or liquidity, are simultaneously determined in search markets. The empirical model exploits variation in the surrounding neighborhood market conditions pertinent to each house to identify the system of price and liquidity equations. The estimates are consistent with search-market theory in that liquidity absorbs part of the capitalization of school quality.

Short interest in exchange-traded funds

Short selling exchange-traded funds (ETFs) has become a common means of speculating or hedging in response to pessimistic expectations about a specific market or sector, as the short interest of ETFs is more than 10 times that of individual stocks, on average. We determine that sector-based ETFs have an abnormally large short interest level, whereas international ETFs have an unusually small short interest level. The level of short interest is larger for ETFs that have a higher trading volume and a lower market capitalization, regardless of the type of ETF assessed. The level of short interest is lower for ETFs representing indexes that have tradable derivatives, but higher for international ETFs representing indexes that have tradable derivatives. We also determine that the level of short interest in an ETF serves as an effective signal of bearish sentiment when considering all ETFs, but is not an effective signal when isolating any particular type of ETF.

Stock Market Anomalies: What Can We Learn from Repurchases and Insider Trading?

We examine whether managers’ trading decisions (both at a firm and personal level) are correlated with trading strategies suggested by the operating accruals and the post-earnings announcement drift (SUE) anomalies. We discuss advantages and disadvantages of the use of managerial trading activity to infer managers’ private valuation about their own securities. Our results provide corroborative evidence for the accruals anomaly, i.e., managers’ repurchase and insider trading behavior varies consistently with the information underlying the operating accruals trading strategy. On the other hand, we do not find corroborative evidence for the SUE anomaly.

Bank capitalization and lending behavior after the introduction of the Basle Accord

In this paper, we provide evidence that banks with a low level of capitalization have reduced their commitment with respect to lines of credit after the introduction of the Basle Accord. A bank's lending behavior reflects its level of commitment towards borrowers, which in turn affects the level of effort it exerts on screening and monitoring the activities of borrowers. We find that the post-Basle Accord market reaction to the announcement of lines of credit issued by banks with a low level of capitalization is significantly lower than the reaction to other types of bank credit announcements. We interpret this result as evidence that some banks have a low level of commitment associated with lines of credit after the Basle Accord.

Price–volume relations of DAX companies

This study provides empirical evidence of the joint dynamics between stock returns and trading volume using stock data of DAX companies. Contemporaneous as well as dynamic interactions are investigated for a period from January 1994 to December 2005 on a daily basis. Our results suggest that there is almost no relationship between stock return levels and trading volume in either direction. We find that trading volume is contemporaneously positively related to return volatility. In addition, we establish that lagged return volatility induces trading volume movements. Finally, we examine dependencies in the tails and find no significant support for the hypothesis of the independence of the maximal values of absolute returns and trading volume.

Tick size change on the Stock Exchange of Thailand

This paper explores the impact of an exogenous tick size reduction on bid-ask spreads, depths, and trading volume on the Stock Exchange of Thailand (SET). On November 5, 2001, the SET implemented a tick size reduction on stocks priced below THB 25. Even though trading on SET is largely dominated by retail investors, the tick reduction produces similar empirical results found in markets where institutional investors are more dominant. Tick reduction on the SET is associated with declines in spreads, and quoted and accumulated market depths. The study finds no significant change in trading volume due to the reduction.

NYSE execution quality subsequent to migration to hybrid

In October 2006, the NYSE began rolling-out phase three of a four-phase plan initiate its new Hybrid trading mechanism. The results show that this new trading platform introduced a much larger proportion of electronic transactions relative to floor auction transactions. This migration to electronic transactions is further evidenced by a mirror shift in price discovery from floor trades to trades marked for automatic electronic execution. In addition, the move to Hybrid trading introduced a significant decrease in inventory control costs, as well as a noticeable increase in trade persistence. Finally, the new trading platform has increased the speed with which orders are met, and has also decreased the proportion of executed shares which receive price improvement.

Investor protection, adverse selection, and the probability of informed trading

The purpose of this study is to investigate the relation between investor protection, adverse selection, and the probability of informed trading. Previous research has established a direct relation between investor protection and firm liquidity, measured by bid-ask spreads and depths. In this study, we test the hypothesis that adverse selection is the mechanism through which poor investor protection leads to higher costs of liquidity. The Hong Kong equity market provides a unique opportunity to compare adverse selection differences across distinct investor protection environments, holding constant the trading platform and currency. Using various bid-ask spread decomposition models and probability of informed trading estimates, we confirm the hypothesized relation between investor protection quality and adverse selection costs. These findings contribute to the literature by establishing one of the links in the chain connecting investor protection to firm valuation.

Trading on inside information when there may be tippees

This paper compares four scenarios of a model in which, for the possible presence of tippees, firm insiders may not be the only persons having inside information. The four scenarios are that of free insider trading, that with a ban on insider trading, that of observable insider trading, and that with full disclosure of information. Each of these scenarios is shown to be strictly more efficient than the one before so long as there is a positive probability that a tippee exists. The paper sheds some light on why and how insider trading should be regulated, and also on the role of the disclosure system in the overall scheme of securities regulation.

Organized labor and information asymmetry in the financial markets

Prior results from the labor relations literature suggest that revealing information weakens management’s position in collective bargaining. Thus, when facing organized labor, management has an incentive to preserve the information asymmetry with outsiders. This study uses a sample from a large cross-section of the economy over several years to test this relation. Results are consistent with this prediction. Strong organized labor is associated with higher bid-ask spreads, higher probability of informed trading, lower trading volume and lower analyst coverage. These relations hold after controlling for numerous factors such as growth opportunities or risk.

Trading Credit Default Swaps via Interdealer Brokers

Credit default swaps (CDSs) are among the most successful financial innovations of recent years, which is reflected in the rapidly expanding market. CDS trading occurs in the over-the-counter market, which relies heavily on broker intermediation to arrange trades. We provide empirical evidence that liquidity in the voice brokered market varies with the particulars of the CDS contracts and that the differences in market structure is reflected in the costs of liquidity. Moreover, the brokered and direct interdealer trading markets seem to be well integrated; thus the higher liquidity costs in the brokered market may reflect the value of intermediation. Hybrid market structures, which combine voice brokerage with an electronic platform, are discussed as a viable alternative to fully automated trading systems.

Are candlestick technical trading strategies profitable in the Japanese equity market?

We show that candlestick charting, the oldest known form of technical analysis, is not profitable in the Japanese equity market over the 1975–2004 period. Candlestick technical analysis, which was developed in Japan in the 1600s, is deeply intertwined with Japanese culture and is very popular in Japan. However, there is no evidence candlestick technical trading strategies add value in either the entire 30 year period, in three 10 year sub-periods or in bull or bear markets.

Price reversals versus price continuations: the transitory price effects of futures trading extension on the underlying stock market

This paper examines the transitory price effects of index futures trading extension on the underlying stock market. Based on the model formulation of George and Hwang (1995) and Amihud and Mendelson (1987) and using the Hong Kong data, we find that the extension of futures trading hour helps to reduce the opening pricing errors and change the correlations between daytime and overnight stock returns. Our finding adds to the literature that the trading behavior of derivatives has a significant influence on the transitory price changes of the underlying cash products.

Not all call auctions are created equal: evidence from Hong Kong

On 25 March 2002, the Hong Kong Exchanges and Clearing Ltd (HKEx) introduced an opening call auction. This trading mechanism is designed to facilitate price discovery in the presence of asymmetric information at the market open, increasing opening price efficiency. The design of the HKEx differs significantly from opening auctions in other markets. Contrary to previous research, the results indicate a decrease in market quality following the introduction of the opening call auction. This decline is largest in the less actively traded stocks.

Strategic timing of annual earnings announcements: evidence from an order-driven market

Using Spanish data, this paper examines, for the first time, the differences in the intraday response of an order-driven market to earnings announcements made during trading and non-trading hours. We show that the speed of reaction depends on timing of the announcement: for overnight (daytime) announcements, the improvement in liquidity is (not) immediate. This finding could explain why Spanish firms prefer to release the bad (good) earnings announcement in trading (non-trading) hours. This strategic timing differs from the traditional disclosure policy in American markets, suggesting that different microstructures may react differently to news releases and, consequently, drive the strategic timing of corporate disclosures.

Competition between financial markets in Europe: what can be expected from MiFID?

The Markets in Financial Instruments Directive (MiFID) could be the foundation of new trading platforms in Europe. This contribution employs insights from the theoretical and empirical literature to highlight some of the possible implications of MiFID. In particular, we argue that more competition will lead to more liquid markets, reflected in lower bid–ask spreads and greater depth. It will also lead to innovation in incumbent markets and stimulate the design of new trading platforms. MiFID has already introduced more competition, as evidenced by the startup of Instinet Chi-X, the announcement of new initiatives, including Project Turquoise and BATS, and the reactions of incumbent exchanges.

Trading Intensity and Real Estate Performance

This paper investigates whether it is possible to create value through the active management of direct property portfolios. Using data from the USA, the UK and Australia, we examine whether trading intensity and portfolio growth explain the risk and return characteristics of listed property companies. The results suggest that beating the market by pursuing tactical asset selection and investment timing strategies is difficult even when acquiring and disposing of properties in illiquid private property markets. When the property type in which the firm specializes is included as a control variable in the regressions, none of the portfolio management intensity indicators developed in this paper is significantly associated with abnormal performance or systematic risk.

Specification analysis of corporate equity financing decision: a conditional residual approach

This article revisits the debate on the nature of private placements by specifying that informed insiders make trading decisions in the secondary market and equity issuance decision in the primary equity market (Lee and Wu (2008)). This article uses conditional residuals from the insider trading regression (abnormal insider trades) and conditional residuals from equity financing choice regression (unexpected equity financing choice) to measure private information. An important advantage of conditional correlation coefficient approach over the two-stage approach (Lee and Wu 2008) in testing the presence of asymmetric information is that the former is bounded by −1 and 1 and thus permits cross-sectional comparisons the relatedness between abnormal insider trades and unexpected equity financing choice.
