Information effects of announced stock index additions: evidence from S&P 400

The study examines the information content of press announcements of S&P 400 additions between 2002 and 2007. Prior research into stock index additions has explained the positive valuation effects of additions to S&P indices mostly in terms of the price pressure hypothesis and downward sloping curve hypothesis. The two hypotheses attribute the positive market reaction purely to index-fund buying rather than information effects of announcements. My empirical investigation further reinforces the credibility of the information hypothesis by showing that the market varies its response to added firms depending on the information released about them at the announcement. The analysis demonstrates that the mode of addition, exchange listing, reason for index change, and firm size can modulate valuation effects of stock index additions. The paper also strengthens the argument that announcements of additions to an S&P index contain new signals about the industries represented by the added firms. Positive and significant wealth effects are exclusively attributable to ??non-member?? rival firms. Overall, the results imply that the market discerns and rewards firms that come from outside the S&P universe (pure additions) and rival firms that are not part of a target index.     

Stock prices and domestic and international macroeconomic activity: a cointegration approach

This paper supports the existence of a significant, long-run relationship between stock prices and domestic and international economic activity in six European economies. Johansen Cointegration tests demonstrate that stock price levels are significantly related to industrial production, business surveys of manufacturing orders, short- and long-term interest rates as well as foreign stock prices, short-term interest rates and production. Variance decomposition methods support the strong explanatory power of macroeconomic variables in contributing to the forecast variance of stock prices. Hence, stock prices are determined by macroeconomic activity.

The impact of reshoring decisions on shareholder wealth

Interest in reshoring, defined as the return of manufacturing and service operations from previously offshored locations to the U.S., has gained momentum recently. Yet, there is no academic evidence on the shareholder value implications of reshoring decisions. This paper analyzes the shareholder wealth effects of 37 reshoring decisions announced by U.S. firms during 2006–2015. Our results indicate that reshoring announcements result in positive abnormal stock returns. Mean (median) abnormal stock returns on reshoring announcements are 0.45% (0.29%), corresponding with a mean (median) market value change of $322.57 million ($31.60 million). Our findings imply that the benefits associated with the reshoring tend to outweigh the costs. This finding is relevant for firms faced with the decision of whether to move business activities from offshore to domestic locations. It is also of interest to policy makers who may seek to further stimulate the reshoring phenomenon.     

Cross-sectional implications of dynamic asset pricing with stochastic volatility and ambiguity aversion

Building on recent research that highlights the importance of macroeconomic volatility and ambiguity aversion in explaining the dynamics of stock returns, in this paper we propose a dynamic asset pricing model that simultaneously accounts for stochastic macroeconomic volatility and ambiguity, assuming that investors deal with uncertainty about the mechanics of macroeconomic fluctuations using first-release consumption and revisions to aggregate consumption on vintage data. Our results show that the proposed model captures a large fraction of the cross-sectional variation of excess returns for a wide range of market anomaly portfolios. Furthermore, while the price of risk for ambiguity is positive and significant for the vast majority of assets under study, macroeconomic volatility yields ambiguous outcomes, although it significantly increases the explanatory power of the model for specific assets. Our results suggest that macroeconomic volatility and ambiguity complement each other in explaining the cross-sectional behavior of stock returns.     

The reaction of security prices to tracking stock announcements

This paper provides some empirical evidence on a relatively new and increasingly prevalent form of equity restructuring called tracking stock. We identify the effects associated with tracking stock announcements by excluding from our sample those announcement events that include other significant news announcements on the event date, such as announcements of acquisitions and earnings. For the 35 announcement events that fit this criteria, we find a mean abnormal return of over 3 percent in the two-day period surrounding the announced proposal to issue a tracking stock, with 30 of the 35 firms in the sample earning positive abnormal returns.

基于Logistic模型的我国房地产开发投资压力测试研究

对我国房地产开发投资风险进行压力测试分析,考虑房地产开发投资的地域性差异,选取三个代表地区——上海、辽宁和贵州,首先分析影响房地产投资的风险因素,然后运用Logistic回归模型建立该地区的房地产投资风险评价模型,确定重要影响因素,设定"异常"情景,最后测试房地产业的抗压能力。研究发现:影响三个地区房地产投资的因素不同,且重要性不一致。房地产销售价格变动与上海房地产投资风险关系最为密切,居民消费价格指数波动对辽宁房地产投资影响最大,而房地产投资的波动直接影响贵州房地产业的健康运行。对这三个重要指标设定极端情景,三个地区的房地产投资风险出现了不同程度的提高,由此得出,在投资这三个地区或与其相似类型的地区时,要充分考虑实际的宏观经济情况,特别是显著指标的变动情况,使投资更加的合理和安全。

Risk,jumps, and diversification

We test for price discontinuities, or jumps, in a panel of high-frequency intraday stock returns and an equiweighted index constructed from the same stocks. Using a new test for common jumps that explicitly utilizes the cross-covariance structure in the returns to identify non-diversifiable jumps, we find strong evidence for many modest-sized, yet highly significant, cojumps that simply pass through standard jump detection statistics when applied on a stock-by-stock basis. Our results are further corroborated by a striking within-day pattern in the significant cojumps, with a sharp peak at the time of regularly scheduled macroeconomic news announcements.     

Explanation for market response to seasoned equity offerings

In this paper, we use a multivariate framework to extend the recent univariate seasoned equity offering (SEO) research that investigated the valuation impact of inside ownership. Our multivariate findings re-enforce and add to the univariate findings as we show that the inside ownership level is a consistent factor in accounting for short-run and long-run returns around SEOs, while the decrease in inside ownership has no impact on short-run returns but influences long-run returns in a manner inconsistent with signaling theory. Compared to prior research, our regression tests do a much better job of accounting for returns associated with SEO announcements. For short-run regression tests, the four major factors associated with superior stock returns are: lower underpricing; greater profitability prior to SEO; lower inside ownership level; and, less stock price variability prior to SEO. For long-run regression tests, the four major conditions linked to superior returns are: greater profitability prior to SEO; smaller inside ownership level; relative size of the offering; and, greater decrease in inside ownership level.     

Politically connected directors and firm value: Evidence from forced resignations in China

The Central Committee of the Communist Party in China issued the No. 18 Document on Oct 30, 2013 to ban government officials from taking any positions in Chinese firms. Using this decision as a unique natural experiment, we examine the causal relation between political connections and firm valuation. We find that the value of firms with politically connected directors drops significantly upon the announcements of the new rule and the resulting director resignations. Furthermore, the decline in valuation is more pronounced when a firm is in a regulated industry, and when a departing director is of vital importance for building and maintaining political connections. Moreover, non-state-owned enterprises suffer more loss of value than their state-owned peers following the resignations of politically-connected directors. Finally, firms exhibit insignificant value loss when their departing directors are of less political importance in allocating resources. These results suggest that hiring politically connected directors has a positive effect on firm valuation in China.     

Macroeconomic influences on the stock market

The paper studies the dynamic interactions among indicators of economic activity, such as industrial production, interest rate and exchange rate, the performance of the foreign stock market, oil prices, and stock returns to examine whether economic activity movements affect the performance of the stock market for Greece. The empirical evidence suggests that stock returns do not lead changes in real economic activity while the macroeconomic activity and foreign stock market changes explain only partially stock market movements. Oil price changes explain stock price movements and have a negative impact on macroeconomic activity.     

Intraday effect of news on emerging European forex markets: An event study analysis

We analyze the impact of euro zone/German and U.S. macroeconomic news announcements and the communication of the monetary policy settings of the ECB and the Fed on the forex markets of new EU members. We employ an event study methodology to analyze intraday data from 2011–2015. Our comprehensive analysis of the wide variety of macroeconomic information during the post-GFC period shows that: (i) macroeconomic announcements affect the value of the new EU country exchange rates, (ii) the origin of the announcement matters, (iii) the type of announcement matters, (iv) different types of news (good, bad or neutral) result in different reactions, (v) markets react not only after the news release but also before, (vi) when the U.S. dollar is the base currency the impact of the news is larger than in the case of the euro, (vii) announcements on ECB monetary policy result in stronger effects than those of the Fed, (viii) temporary inefficiencies are present in new EU country forex markets, (ix) new EU country exchange rates react differently to positive US news during the EU debt crisis compared to the rest of the period.     

Impact of network investor sentiment and news arrival on jumps

This paper studied the influence of news announcements and network investor sentiment on Chinese stock index and index futures market jumps. A machine learning text analysis algorithm was employed to measure investor forum sentiment. It was found that news arrivals were an important reason for jump occurrences, jumps were significantly associated with network investor sentiment, and while occasionally the news and network investor sentiment resulted in simultaneous market jumps, they appeared to be relatively independent. The network investor sentiment time-lag and asymmetric effects were also tested, from which it was found that network investor sentiment had a significant asymmetric effect on the jumps, but time-lag effects had little influence. News announcements and the top 25% of the extreme network sentiments were found to explain more than 50% of the jumps, with extreme sentiments tending to increase the volatility of the news-related jumps and persistently influencing returns after the news-related jumps.     

International mergers and acquisitions: A jump diffusion model application

This paper empirically investigates international mergers and acquisitions (M&As) of foreign targets and bidders by analyzing the stock price behavior of the firms involved. The jump diffusion model is employed to study the effects of the M&A announcements on stock prices. The results indicate that acquisition announcements are perceived as a surprise by the market, but prices seem to adjust rather rapidly, supporting the semi-strong form of the market efficiency hypothesis. In addition, a comparison of the pure diffusion and jump diffusion models indicates that the jump diffusion model is statistically superior to the traditional event study methodology (pure diffusion model).

Housing and cost of living: Application to the Spanish regions

Spain is a home-owner economy, and housing is a key good for determining the cost of living. However, its treatment in indices such as the Spanish Consumer Price Index (CPI) makes it impossible to measure the real impact of housing on the cost of living. This issue is especially relevant at the regional level, where the differences in the housing markets are very substantial. This paper demonstrates the importance of taking account of owner occupied housing in a measure of the cost of living for Spain.

Stock-market reaction to growth-induced dividend cuts: Are investors myopic?

This paper focuses on shareholder reaction to growth-motivated dividend cuts and omissions. The results reveal that although growth announcements mitigate the capital loss induced by dividend decreases, the stockmarket response to growth-oriented dividend cuts is still strongly negative. However, the capital loss suffered by investors is significantly reduced when dividend cuts are accompanied with stock dividends. Two potential explanations of the results are explored: (1) shareholders find the immediate benefits of stock dividends more attractive than the potentially higher future rewards of investment opportunities; and (2) shareholders overreact to dividend announcements. Analysis of the performance of the firms for two years following the dividend cut indicates weak support for the overreaction hypothesis.     

Mortgagor Motivations in Prepayments for Adjustable Rate Mortgages

This paper provides the first rigorous analysis of residential adjustable mortgage prepayment using individual ARM mortgage data in Singapore. The prepayment rate for residential mortgages is low and is dominated more by macroeconomic factors than mortgage–specific factors. Specifically, the prepayment rate is increasing in residential property prices, but decreasing in income as proxied by GDP and volatility in mortgage rates. There is weak evidence to suggest that prepayment is increasing in the borrower's age, mortgage rate hikes, cash–availability variables and sentiments of the stock market, and decreasing in the price premium over valuation, payment–to–income ratio, loan–to–value ratio, loan term and floor level of the property.     

Jumps,cojumps and macro announcements

We use recently proposed tests to extract jumps and cojumps from three types of assets: stock index futures, bond futures, and exchange rates. We then characterize the dynamics of these discontinuities and informally relate them to US macroeconomic releases before using limited dependent variable models to formally model how news surprises explain (co)jumps. Nonfarm payroll and federal funds target announcements are the most important news across asset classes. Trade balance shocks are important for foreign exchange jumps. We relate the size, frequency and timing of jumps across asset classes to the likely sources of shocks and the relation of asset prices to fundamentals in the respective classes.
