Financial analysts and price discovery

We show that whether or not a bank/brokerage firm has top‐rated financial analysts and high Wall Street Search rankings for their research is significantly related to that firm's contribution to price discovery, the process by which information is incorporated into stock prices. Our study relates cross‐sectional characteristics of the quality of brokerage research, the asymmetric information environment, and order flow volume to a microstructure measure of price discovery developed by Granger and Gonzalo. We measure analysts’ research quality with an industry‐specific ranking by institutional investors, with an opinion survey of trading desk personnel, and with the number of top 3 analysts across all industries employed by the bank/brokerage firm.     

Financial stress and economic dynamics: The transmission of crises

A financial stress index for the United States is introduced—one used by the staff of the Federal Reserve Board during the financial crisis of 2008–2009—and its׳ interaction with real activity, inflation and monetary policy is investigated using a Markov-switching VAR model, estimated with Bayesian methods. A “stress event” is defined as a period of adverse latent Markov states. Results show that time variation is statistically important, that stress events line up well with historical events, and that shifts to stress events are highly detrimental for the economy. Conventional monetary policy is shown to be weak during such periods.     

Financial crises and political crises

The simultaneous determination of financial default and political crises is studied in an open economy model. Political crises accompany default in equilibrium because of an information transmission conflict between the government and the public. Multiple equilibria are possible: if foreign lenders are pessimistic about the country's stability, they demand a high interest on the debt, exacerbating distortions and possibly leading to political crisis; but if lenders are optimistic, the cost of the debt falls and political crises disappear. In such a case, international liquidity packages can select the best equilibrium and rule out political crises at negligible cost.     

Overnight public information,order placement,and price discovery during the pre-opening period

This study examines the impact of corporate news announcements released overnight on price discovery during the pre-opening period in the Australian Securities Exchange. Our results suggest that the presence of these announcements increases the efficiency of indicative opening prices and that the intensity of these announcements significantly influences the aggressiveness of pre-opening orders. Using earnings announcements to compare the speed of price adjustments in response to overnight and daytime information of a homogeneous type, we find that prices respond immediately to overnight news upon the commencement of trading, whereas adjustments based on trading-hours news tend not to be instantaneous. Overall, our evidence highlights the important role of the pre-opening period in price discovery and the prospect of further enhancing this role by timing the release of public information to occur during non-trading hours.     

Financial crises: reducing pro-cyclicality

The swing in favour of markets weakened regulation, created incentives for excessive risk-taking, and reduced transparency and diversity. As a result, financial markets became more pro-cyclical. The right combination of regulation and markets is required to reverse this. Principle-based reform should aim to change behaviour rather than forbid activity. Central Bank accommodation has been blamed for the crisis, but excessive leverage due to lax regulation was of a much greater magnitude than any monetary imbalance. Capital's mobility and arbitrage in response to regulation, implies changes must be adopted globally. A diversity of voice and power is essential to enable implementation of the core set of proposals that can make financial markets more robust.     

Financial globalization, financial crises and contagion

Two observations suggest that financial globalization played an important role in the recent financial crisis. First, more than half of the rise in net borrowing of the U.S. non-financial sectors since the mid-1980s has been financed by foreign lending. Second, the collapse of the U.S. housing and mortgage-backed-securities markets had worldwide effects on financial institutions and asset markets. Using an open-economy model where financial intermediaries play a central role, we show that financial integration leads to a sharp rise in net credit in the most financially developed country and to large asset price spillovers of country-specific shocks to bank capital. The impacts of these shocks on asset prices are amplified by bank capital requirements based on mark-to-market.     

Latency,liquidity and price discovery

The speed of trading is an important factor in modern security markets, although relatively little is known about the effect of speed on liquidity and price discovery, two important aspects of market quality. On April 23, 2007, Deutsche Boerse made an important upgrade to their trading system. With the 8.0 release of Xetra, system latency was reduced from 50 ms to 10 ms. Subsequently, both quoted and effective spreads decreased, which are mainly concentrated in small- and medium-sized stocks. This increase in liquidity is due to dramatically lower adverse selection costs that were only partially translated into higher liquidity. We interpret this as a decrease in the competition between liquidity suppliers who are able to increase their revenues by more than 90 million euros. The contribution of quotes to price discovery doubles to 90% post upgrade, indicating that prices are more efficient.     

Asymmetric information consolidation and price discovery: Inferring bad news from insider sales

Due to the paucity of sources of negative firm‐specific information, US capital markets have more difficulty identifying and incorporating bad news into stock prices than they do good news. Even though insider selling is a potentially important proxy for undisclosed bad news, researchers have difficulty ex ante identifying information‐based sales due to an inability to separate liquidity‐motivated from information‐based insider trades. We hypothesize that when insiders in multiple firms sell shares of one firm in which they are insiders and at the same time buy shares of other insider portfolio firms, the sale is more likely to be information‐based, since the proceeds are reinvested. Conversely, when an insider sells one firm without purchasing others or sells multiple insider firms the sale is likely liquidity‐motivated. We find that insider sales identified as information‐based using this algorithm are followed by significant negative abnormal returns. Information‐based sales are also more likely to be associated with delistings, earnings declines and earnings restatements. Analysts are also more likely to revise their earnings forecasts downwards for these firms. It is thus possible to ex ante identify insider sales with information content. Our results will be of interest to investors and also to regulators designing insider trading rules.     

Financial flows,financial crises,and global imbalances

In this lecture I document the proliferation of gross international asset and liability positions and discuss some consequences for individual countries’ external adjustment processes and for global financial stability. In light of the rapid growth of gross global financial flows and the serious risks associated with them, one might wonder about the continuing relevance of the net financial flow measured by the current account balance. I argue that global current account imbalances remain an essential target for policy scrutiny, for financial as well as macroeconomic reasons. Nonetheless, it is critically important for policymakers to monitor as well the rapidly evolving structure of global gross assets and liabilities.     

Financial crises and coordination failure: A comment

The three papers of this session link financial crises (explicitly or implicitly) to coordination failure. In Bryant (Journal of Banking and Finance, 2002), the possibility of coordination failure is due to complementarity in the productive technology. In Chui et al. (Journal of Banking and Finance, 2002), foreign lenders to a small country fail to coordinate on the optimal strategy rolling over short-term loans. Finally, Amable et al. (Journal of Banking and Finance, 2002) implicitly introduce coordination failure through a production function with external increasing returns to scale. This sort of “thick markets” externality can be viewed as a reduced form that stands for coordination problems in a non-Walrasian economy.     

Financial flexibility,corporate investment and performance: evidence from financial crises

This study examines the impact of financial flexibility on the investment and performance of East Asian firms over the period 1994–2009. We employ a sample of 1,068 firms and place particular emphasis on the periods of the Asian crisis (1997–1998) and the recent credit crisis (2007–2009). The results show that firms can attain financial flexibility, primarily through conservative leverage policies and less commonly by holding large cash balances. Financial flexibility appears to be an important determinant of investment and performance, mainly during the Asian 1997–1998 crisis. In particular, firms that are financially flexible prior to this crisis (1) have a greater ability to take investment opportunities, (2) rely much less on the availability of internal funds to invest, and (3) perform better than less flexible firms during the crisis. Our analysis covering the credit crisis period of 2007–2009 suggests that some of the advantages of flexible firms towards investing persist but are significantly less pronounced over that period. We also find that the value of financial flexibility is region/country specific, which may be explained by the fact that different regions/countries often adopt different macroeconomic policies and operate in diverse economic/legal environments.     

Local investors,price discovery,and market efficiency

This study examines the effect of locally informed investors on market efficiency and stock prices using large power outages, which are exogenous events that constrain trading. Turnover in stocks headquartered in an outage area with 0.5% of U.S. electrical customers drops by 3–7% on the first full day of the outage, and bid–ask spreads narrow by 2.5%. Firm-specific price volatility is 2.3% lower on blackout dates. This effect is larger for smaller, lesser-known stocks and in higher income areas. Consistent with a valuation discount and higher expected returns for stocks with more informed traders, firms with a one-standard-deviation higher local trading propensity have market-to-book values that are 5% lower, Tobin's Q that is 6% lower, annualized four-factor alphas that are 1.2% higher, and average spreads that are 6.5% higher. Together, the evidence suggests that informed investors contribute disproportionately to both liquidity and price discovery, and that these contributions are reflected in valuations and expected returns.     

Encoding of high-frequency order information and prediction of short-term stock price by deep learning

Predicting the price trends of stocks based on deep learning and high-frequency data has been studied intensively in recent years. Especially, the limit order book which describes supply-demand balance of a market is used as the feature of a neural network; however these methods do not utilize the properties of market orders. On the other hand, the order-encoding method of our prior work can take advantage of these properties. In this paper, we apply some types of convolutional neural network architectures to order-based features to predict the direction of mid-price trends. The results show that smoothing filters which we propose to employ rather than embedding features of orders improve accuracy. Furthermore, inspection of the embedding layer and investment simulation are conducted to demonstrate the practicality and effectiveness of our model.     

Financial crises and labor market turbulence

Financial crises in emerging markets trigger a significant reallocation of labor as exchange rate depreciations and interest rate increases cause relative prices to change drastically. Household survey data for Mexico reveal that individuals who switched industry or occupation during the 1994–1995 crisis lost about 10% of their hourly earnings on average compared to similar workers who did not move. This suggests that many workers became less productive in the process of migrating to different economic activities. These productivity losses, in turn, can explain about 40% of the observed fall in TFP in Mexico in 1995.     

Trading costs and price discovery

The price discovery roles of a set of related markets or securities have been investigated in many different settings where trading costs effect is often commingled with other trading arrangement factors. In Hong Kong, regular futures and mini futures contracts as well as their underlying spot asset are all traded on a same electronic trading platform. The trading arrangements thus provide us with a unique setting where we can isolate the impacts of transaction costs on price discovery. Using Hasbrouck’s (J Finance 50:1175–1199, 1995) information share approach, it is found that in Hong Kong, the regular futures contracts market plays a dominant role in price discovery while the mini futures and cash index markets play minor roles. The results in this paper provide an unequivocal support to the trading costs hypothesis.     

Financial crises: Lessons from the Nordic experience

The current financial crisis is the 19th such crisis in the post-war period in advanced economies. Recent literature classifies the Nordic crises in Norway, Sweden and Finland in late 1980s and early 1990s among the Big Five crises that have happened before the current crisis, which is now of a global nature. This paper outlines the developments of the Nordic crises, reasons behind them and crisis management by the authorities. Relatively more emphasis is placed on the Finnish crisis, as it was the deepest one. The paper concludes by considering the lessons that can be drawn from the Nordic crises.     

Financial crises,bank risk exposure and government financial policy

A macroeconomic model with financial intermediation is developed in which the intermediaries (banks) can issue outside equity as well as short term debt. This makes bank risk exposure an endogenous choice. The goal is to have a model that can not only capture a crisis when banks are highly vulnerable to risk, but can also account for why banks adopt such a risky balance sheet in the first place. We use the model to assess quantitatively how perceptions of fundamental risk and of government credit policy in a crisis affect the vulnerability of the financial system ex ante. We also study the effects of macro-prudential policies designed to offset the incentives for risk-taking.     

Measuring price discovery: The variance ratio, the R, and the weighted price contribution

We analyze the statistical properties of three price discovery measures: The variance ratio, the weighted price contribution (WPC), and the R² of unbiasedness regressions. We find that, if the price process is a driftless martingale, only the WPC is an unbiased estimator for the return variance explained during a time interval. For autocorrelated processes with a drift, only the R² of the unbiasedness regression is consistent, but it is biased for small samples.     

Private information flow and price discovery in the U.S. treasury market

Using intraday data, we identify the intensity of private information flow in the U.S. Treasury market. Our results show that the intensity of private information flow is highly correlated with public information shocks and higher for longer maturity bonds. More importantly, we find that bond price changes associated with high intensity of private information flow tend to be persistent, whereas those associated with low intensity of private information flow are more likely reversed. While public information and private information are the main determinants of bond price variations on days with news announcements, private information and liquidity shocks are important determinants of bond price variations on days with no significant events. Finally, we show that the depth of limit order book is inversely related to the intensity of private information flow. Nevertheless, informed dealers do not seem to use hidden orders to disguise their trading intentions.
