Automation, speed, and stock market quality: The NYSE's Hybrid

Automation and trading speed are increasingly important aspects of competition among financial markets. Yet we know little about how changing a market's automation and speed affects the cost of immediacy and price discovery, two key dimensions of market quality. At the end of 2006 the New York Stock Exchange introduced its Hybrid Market, increasing automation and reducing the execution time for market orders from 10 seconds to less than one second. We find that the change raises the cost of immediacy (bid-ask spreads) because of increased adverse selection and reduces the noise in prices, making prices more efficient.     

Strategic trading by index funds and liquidity provision around S&P 500 index additions

We examine the trades of index funds and other institutions around S&P 500 index additions. We find index funds begin rebalancing their portfolios with the announcement of composition changes and do not fully establish their positions until weeks after the effective date. Trading away from the effective date is more prevalent for stocks with lower levels of liquidity and among large index funds, which is consistent with index funds accepting higher tracking error in order to reduce the price impact of their trades. Small and mid-cap funds provide liquidity to index funds around additions, and added stocks with a greater proportion of these natural liquidity providers experience lower inclusion returns.     

Investor type trading behavior and trade performance: Evidence from the Thai stock market

This paper examines the trading behavior and decomposes the trading performance of foreign, individual and institutional investors as well as proprietary traders in a dynamic emerging stock market, the Stock Exchange of Thailand. Foreign investors follow a positive feedback, momentum strategy and are good short term market timers but have poor security selection performance in poor markets, thus suggesting that they have a macro (market timing) but not a micro (security selection) informational advantage relative to local investors. Institutions and proprietary traders have poor security selection trading performance. Individuals display herding behavior and have fairly good security selection performance, but individual investors appear to compensate proprietary traders for the provision of short term liquidity by proprietary traders, so individuals' security selection gains are canceled out by market timing losses.     

Good news, bad news and rating announcements: An empirical investigation

In this paper we employ a new approach to test the contribution of information in rating announcements. This is the first study to test and corroborate how the CDS market responds to rating actions after controlling for the presence of concurrent public and private information. We show that since the clustering of rating announcements characterizes economically significant developments, the common practice of using “uncontaminated” samples underestimates market response. As in previous studies, we find that the market response to bad news is stronger than to good news. Nevertheless, bad news and negative rating announcements tend to cluster. Therefore, the residual contribution of negative rating announcements is small and in some cases insignificant. Positive rating announcements are less frequent and less clustered, though their residual contribution is still significant.     

Perks and the informativeness of stock prices in the Chinese market

While the literature shows that perks can affect firm values positively or negatively, we argue that firms with higher perks are more likely to be associated with a lower quality of financial reporting, which, in turn, can affect the informativeness of stock prices. Based on hand-collected data on perks from Chinese listed firms, we find that firms with lower perks are associated with higher informativeness of stock prices (or lower R-square). Moreover, the positive association between perks and R-square is shown to be weaker for firms with higher financial reporting quality through audit and earnings quality measures.     

The liquidity effect for open market operations

The liquidity effect is the negative relationship between the supply of federal funds and the overnight federal funds rate. Deviations of the federal funds rate from its target can be interpreted as demand innovations for federal funds. Permanent adjustments to demand are modeled as an unobserved component and estimated using the Kalman filter to identify liquidity effects. The demand-based approach for identifying the liquidity effect contrasts previous work which concentrates on errors forecasting the supply of federal funds. This paper finds a liquidity effect several times larger than that from previous studies, indicating the market for federal funds is less liquid than previously thought. The effect of a $1 billion increase in open market operations over a 1-week period is a decrease of the federal funds rate by about 12 basis points.     

Local underwriter oligopolies and IPO underpricing

We develop a theory of initial public offering (IPO) underpricing based on differentiated underwriting services and localized competition. Even though a large number of investment banks compete for IPOs, if issuers care about non-price dimensions of underwriting, then the industry structure is best characterized as a series of local oligopolies. We test our model implications on all-star analyst coverage, industry expertise, and other non-price dimensions. Furthermore, we posit that venture capitalists (VCs) are especially focused on all-star analyst coverage, and develop the analyst lust theory of the underpricing of VC-backed IPOs. Consistent with this theory, we find that VC-backed IPOs are much more underpriced when they have coverage from an all-star analyst.     

The subprime asset-backed securities market and the equity prices of large complex financial institutions

In this paper, we investigate the relationship between the subprime asset-backed collateralized debt obligations (CDO) market and Large Complex Financial Institutions (LCFIs). We attempt to account for the dynamics between the ABX index returns and the banks’ equity returns through conditioning our analysis on the historical correlation between the variables. Three key results emerge from the analysis. First, we find a positive correlation between movements of the ABX index and the equity returns for all the LCFIs. Second, the volatility of ABX index returns tend to be transmitted to the volatilities of the equity returns of the financial institutions. Third, ABX prices changes lead equity returns changes of the European-based LCFIs. For the US LCFIs a two-way linkage emerges.     

Stock market trading activity and returns around milestones

We study the relation between daily stock market trading activity and the Dow Jones Industrial Average's (DJIA) movement around millenary milestones—numbers that end in three zeros. We find aggregate turnover to be 5% lower when the DJIA level is less than 1% away from the nearest milestone. The effect emerges as the DJIA approaches a milestone from below, and is stronger for first-time milestones compared to subsequent passages. The aggregate price impact is large, such that daily stock returns show a negative abnormal performance of − 10 basis points. Our findings suggest that millenary milestones of the DJIA play a role in some investors' decision making.     

Working for the enemy? The impact of investment banker job changes on deal flow

This paper examines the impact of job changes by prominent investment bankers on the M&A and equity market shares of investment banks. Using a hand-collected sample of job changes between 1998 and 2006, we find that after controlling for deal and bank-level characteristics, hiring a banker from an investment bank with a more prominent industry presence has a positive impact on both equity and M&A market share for the gaining bank and a negative impact on the losing bank's M&A market share. After the banker switches firms, we find a significant amount of business following the banker from the losing bank to the gaining bank, particularly when the relationship is strong between the client firm and the banker. Abnormal returns around the announcement of a banker changing employers are positive and significant for the gaining bank, suggesting that the market views banker additions as value increasing. Overall, our results suggest human capital is a critical component of investment banking deal flow.     

Are liquidity and corporate control priced by shareholders? Empirical evidence from Swiss dual class shares

Stadard asset pricing models generally exclude corporate control and liquidity considerations as joint explanatory factors of the stock price formation process. This empirical study investigates their influence on Swiss Bearer and Registered share prices issued by the same firm. It is shown that the statistical properties of both shares' returns differ without implying profitable arbitrage opportunities. A multifactor model of the ‘premium’ between Bearer and Registered stock prices is then proposed and tested. The results show that the freely negotiable equity book value, the existence of dominant shareholder positions and ownership transfer regime changes are significant variables in explaining the dual class share price differential.     

Stock market volatility and the crash of 1987: evidence from six emerging markets

This paper studies volatility, risk premia and the persistence of volatility in six emerging stock markets before and after the 1987 stock market crash. The empirical investigation is conducted by means of the GARCH in the mean model (GARCH-M) and monthly data from Argentina, Greece, India, Mexico, Thailand, and Zimbabwe between January of 1976 and August of 1994. Results indicate changes in the ARCH parameter, risk premia and persistence of volatility before and after the 1987 crash. But these noted changes are not uniform and depend upon the individual markets. Factors other than the 1987 crash may also be responsible for the changes.     

Announcement effects of convertible bond loans and warrant-bond loans: An empirical analysis for the Dutch market

This study investigates the announcement effects of offerings of convertible bond loans and warrant-bond loans using data for the Dutch market. The event study analysis shows that announcement effects of convertible bonds are associated with positive but insignificant abnormal returns and that announcements of warrant-bonds are associated with significant positive abnormal returns. These findings are similar to the results for Japanese hybrid debt, as reported by Kang et al. (1995) (Kang, J.K., Kim, Y.C., Park, K.J., Stulz, R.M., 1995. Journal of Financial and Quantitative Analysis, pp. 257–270) and Kang and Stulz (1996) (Kang, J.K., Stulz, R.M., 1996. Review of Financial Studies, pp. 109–139), but they contrast with studies for the United States that generally find significant negative abnormal returns for convertible bond loans and insignificant negative abnormal returns for warrant-bond loans. Our results cannot be attributed to differences in the corporate governance structures of the Netherlands and the United States. We find that the positive abnormal returns for the warrant-bond loans are caused by the packaging of the announcements with other (good) firm-specific news.     

Control-ownership wedge and investment sensitivity to stock price

This study examines whether insiders’ incentives for private control benefits affect investment sensitivity to stock price. While Chen et al. (2007) link stock price informativeness to firms’ learning from the stock market, we offer an alternative agency-cost based explanation. Using a total of 2822 firms from 22 countries in East Asia and Western Europe, we document a strong negative association between control-ownership wedge and investment-q sensitivity, suggesting that insiders’ incentives for private control benefit reduce their propensity to listen to the market. Furthermore, the negative impact of wedge on investment-q sensitivity is primarily driven by sub-optimal investments. Overall, we provide evidence that agency problem is an important factor that determines the learning from the stock market in capital allocation.     

Corporate equity ownership, investment, and product market relationships

This paper examines the effect of corporate equity ownership on investment when firms have product market relationships. Firms have incentives to hold long equity positions when their products are complements. These equity positions induce the firms to increase their real investment expenditures. In contrast, firms have incentives to hold short equity positions when their products are substitutes. These short positions commit the firms to a more aggressive product market stance, and also result in increased real investment expenditures. Our model offers an explanation for the empirical relationship between the establishment of corporate equity stakes and increased investment spending documented by Allen and Phillips (2000).     

The persistent effects of a false news shock

In September 2008, a six-year-old article about the 2002 bankruptcy of United Airlines' parent company resurfaced on the Internet and was mistakenly believed to be reporting a new bankruptcy filing by the company. This episode caused the company's stock price to drop by as much as 76% in just a few minutes, before NASDAQ halted trading. After the “news” had been identified as false, the stock price rebounded, but still ended the day 11.2% below the previous close. We explore this natural experiment by using a simple asset-pricing model to study the aftermath of this false news shock. We find that, after three trading sessions, the company's stock was still trading below the two-standard-deviation band implied by the model and that it returned to within one standard deviation only during the sixth trading session. On the seventh day after the episode, the stock was trading at the level predicted by the asset-pricing model. We investigate several potential explanations for this finding, but fail to find empirical evidence supporting any of them. We also document that the false news shock had a persistent negative effect on the stock prices of other major airline companies. This is consistent with the view that contagion effects would have dominated competitive effects had the bankruptcy actually taken place.     

Stock reaction to dividend savings of convertible preferred calls: Free cash flow or price pressure effects?

Calls of in-the-money convertible preferred stock typically induce dividend savings for the firm, since preferred dividends exceed common stock dividends. Prior research finds that these savings are negatively related to stock returns at call announcement and argues that the market expects managers to abuse the increased free cash flow. This paper finds that dividend savings are closely related to call size, suggesting other explanations. Larger calls experience a more negative announcement reaction. Consistent with temporary liquidity effects, there is a price reversal during the conversion period, which is greater for larger calls.     

Do institutional investors have superior stock selection ability in China?

This paper uses unique data on the shareholdings of both institutional and individual investors to directly investigate whether institutional investors have better stock selection ability than individual investors in China. Controlling for other factors, we find that institutional investors increase (decrease) their shareholdings in stocks that subsequently exhibit positive (negative) short- and long-term cumulative abnormal returns. In contrast, individual investors decrease (increase) their shareholdings in stocks that subsequently exhibit positive (negative) short- and long-term cumulative abnormal returns. These findings indicate that institutional investors have superior stock selection ability in China.     

International business: determinants of interbank activities

This paper investigates the determinants of the international interbank market, a significant component of international trade in financial services. The sample encompasses both monthly and quarterly data from 1983 to 1993. The superiority of the monthly results suggest that the interbank market should be modelled within a short-term framework. This data interval captures the short-term movement of funds between currencies, Eurobonds, the nonbank market and the domestic banking market by banks to maximize returns. Moreover, the interbank market does not necessarily move in line with fundamental trade and income variables. Rather, the market is sensitive to return differentials, the relative cost of capital, the yield curve and international nonbank assets. The empirical results also indicate that nationality remains important in interbank trading because of the advantages it imparts on the home country in dealing in its home currency, particularly if that currency is a vehicle currency.     

Liquidity, analysts, and institutional ownership

In this paper, we investigate the empirical relationship between institutional ownership, number of analysts following and stock market liquidity. We find that firms with larger number of financial analysts following have wider spreads, lower market quality index, and larger price impact of trades. However, we find that firms with higher institutional ownership have narrower spreads, higher market quality index, and smaller price impact of trades. In addition, we show that changes in our liquidity measures are significantly related to changes in institutional ownership over time. These results suggest that firms may alleviate information asymmetry and improve stock market liquidity by increasing institutional ownership. Our results are remarkably robust to different measures of liquidity and measures of information asymmetry.
