Coupling News Sentiment with Web Browsing Data Improves Prediction of Intra-Day Price Dynamics

2015

The new digital revolution of big data is deeply changing our capability of understanding society and forecasting the outcome of many social and economic systems. Unfortunately, information can be very heterogeneous in the importance, relevance, and surprise it conveys, affecting severely the predictive power of semantic and statistical methods. Here we show that the aggregation of web users' behavior can be elicited to overcome this problem in a hard to predict complex system, namely the financial market. Specifically, our in-sample analysis shows that the combined use of sentiment analysis of news and browsing activity of users of Yahoo! Finance greatly helps forecasting intra-day and dai…

Money and equity returns in the Euro area

2010

Abstract This study examines the impacts of liquidity on equity returns in the euro area during the period 1987–2001. The main contribution of the study is that the money demand is carefully considered while estimating the liquidity. We provide evidence that in part the impact of money on equity returns depended on the measure used for liquidity (real money supply, real money gap and monetary overhang). However, a unanimous inference was made that over time an increase in liquidity has a negative impact on equity returns. This is interpreted as being due to the positive impact of money on inflation. Accordingly, an increase in liquidity generated expectations of inflation, which led to a de…

The Legacy and the Tyranny of Time: Exit and Re-Entry of Sovereigns to International Capital Markets

2018

We use a novel continuous-time Weibull model (without and) with a change-point in the duration dependence parameter to investigate the duration of the exit and re-entry of sovereigns to international capital markets. Relying on annual data for a large panel of countries over the period 1970-2011, we find that, as the reputation of debtor countries as good (bad) borrowers solidifies over time, those episodes are more likely to end - i.e. the "legacy of time". Debtor countries can take advantage of the "benefit of doubt" of creditors during short exit spells. However, when exits are long and the reputation as a bad borrower emerges, no more "complacency" makes it more difficult for them to bo…

Adaptative Network Topology for Data Centers

2016

Data centers have an important role in supporting cloud computing services (such as email, social networking, web search, etc.) enterprise computing needs, and infrastructure-based services. Data center networking is a research topic that aims at improving the overall performances of the data centers. It is a topic of high interest and importance for both academia and industry. Several architectures such as FatTree, FiConn, DCel, BCube, and SprintNet have been proposed. However, these topologies try to improve the scalability without any concerns about energy that data centers use and the network infrastructure cost, which are critical parameters that impact the performances of data centers…

The Risk-Relevance of Accounting Data: Evidence from the Spanish Stock Market

2006

This paper analyses the relevance of accounting fundamentals to inform about equity risk as measured by the cost of equity capital. Assuming the latter is a summary measure of how investors make decisions regarding the allocation of resources, the strength of the association between the cost of capital and the accounting-based measures of risk indicates how important these measures are for market participants when making economic decisions. To infer the cost of equity capital, we use the O'Hanlon and Steele's method, which is based on the residual income valuation model. Moreover, we use the insights from this model to provide a theoretical underpinning for the choice of the accounting vari…

Equity Issues in the Spanish Stock Market: Windows of Opportunity, Earnings Management or Market Timing?

2005

We investigate whether the market sentiment and/or the specific operating performance of firms that conducted an equity issue on the Spanish stock market during the period 1993-2000 are related to the long-run stock-return underperformance in the year following the issue of small and medium firms. Our results reveal that equity issues were conducted by large firms just when the market showed optimistic expectations towards large firms in general. This overoptimism towards large issue firms was related to the 1990s technology boom in the case of initial public offerings (IPO), but we detect earnings management by large firms that conducted a seasoned equity offering (SEO). In this context, s…

Equity-worthiness and equity-willingness: key factors in private equity deals

2014

While access to private equity funds (PEFs) provides a unique opportunity for firms to set up sturdy growth paths, how PEFs select companies is an unknown process to entrepreneurs and business owners. This study aims to offer insights regarding the private equity market to entrepreneurs searching for external capital. We analyzed a novel dataset of 240 pre-deal negotiations between small- and medium-sized Italian companies and a closed-end fund. Results indicate that the successful closing of a deal depends on more than just the target firm's equity-worthiness (i.e., the company's ability to meet the expectations of a private equity investor). In fact, there is another dimension: the target…

Effects of Behavioural Finance on Emerging Capital Markets

2014

Abstract A recent common view of finance experts is that it is becoming increasingly difficult to understand how the economy as a whole works. Although the efficient market theory might be considered an ideal model enabling the interpretation of market behavior, it has begun to lose ground, and the rationality hypothesis failed to explain the excessive volatility of the returns and trading volume recorded on both developed capital markets and emerging ones. Adding the behavioral finance perspective to the equation can help us to understand better how market agents will react. In this article, we investigate the factors that may explain the trading volume evolution on two emerging capital ma…

Effects of Behavioural Factors on Human Financial Decisions

2014

Abstract In this article, we investigate the factors that may explain the trading volume evolution on two emerging capital markets, Romania and Brazil. We analyze the impact of both investors who ground their trading behaviour on rational expectations and investors who show psychological and emotional facets of the human decision, which we call behavioural errors, as independent variables on the trading volume as dependent variable. The results indicate that trading is influenced by the investors’ irrational behaviour. Thus, the rationality hypothesis can be rejected for both capital markets.

Venture capitalists' decision-making in small equity markets: a case study using participant observation

2004

Despite significant academic research undertaken in the field of venture capital decision-making process, the dimension and maturity of equity market has not yet been considered as an important contextual factor. Aiming at developing an understanding on how venture capitalists (VCs) select early-stage projects in small equity markets, a pilot study using participant observation technique has been conducted in a Portuguese venture capital firm. The findings indicate that the decision-making process and the criteria used by VCs in this market context differ significantly from those used in the developed equity markets. Regarding the decision-making process as a whole, it appears to be more in…
