The volatility of comprehensive income and its association with market risk

Financial statement preparers claim that the ‘excess’ volatility of comprehensive income (CI) confuses financial statement users. We examine the volatility and risk relevance of CI, relative to net income, for a sample of 92 New Zealand nonfinancial firms for the period 2003–2010. The results show that CI is more volatile than net income. However, the volatility of CI incremental to net income is not related to market risk. Furthermore, the incremental volatility of CI does not modify the pricing of net income. These results hold when asset revaluations are excluded from other CI.     

Does reporting position affect the pricing of the volatility of comprehensive income?

The FASB changed the reporting policy for comprehensive income (CI) by issuing ASU No. 2011-05, which requires CI be reported in performance statements (i.e., either a single income statement with net income or a separate statement of CI following the income statement) rather than the previously allowed equity statements. We examine whether the change in reporting position of CI led to higher market pricing of CI volatility incremental to NI volatility (“incremental CI volatility”), as measured by the price-earnings relationship. We find that the market pricing of incremental CI volatility increased from the pre- to the post-ASU period for non-financial firms forced to change the reporting position of CI from equity to performance statements. The increase is more prominent for firms that switched to the income statement than for firms that switched to a separate statement of CI. Further, we find that the increased market pricing of incremental CI volatility translates into lower valuation weights on other comprehensive income.     

我国商业银行经营投资银行业务对风险影响的实证研究

本文以2009-2018年19家商业银行为研究对象,运用波动性分析、相关性分析及面板数据回归分析方法,考察了经营投资银行业务对银行风险的影响。研究结果表明,投资银行收入无明显周期性趋势,波动性明显高于利息净收入,经营投资银行业务会加剧银行业收入的不确定性,但由于收入占比较小,投资银行业务并非造成我国银行业收入波动的主要因素。多数银行的投资银行收入与利息净收入表现为正相关性,银行难以通过经营投资银行业务实现风险分散目的。投资银行业务对银行风险影响的回归结果较为显著,随着投资银行收入在银行收入结构中的权重越来越大,银行多元化收入程度随之加深,银行风险也随之下降。     

Are there diversification benefits of increasing noninterest income in the Chinese banking industry?

This paper assesses the potential diversification benefits of the increasing reliance on nontraditional business activities based on data from the Chinese banking industry in 1986–2008. At the aggregate level, there are diversification benefits of the increase in noninterest income. However, noninterest income has higher volatility and cyclicality than net interest income, and the marginal benefit of diversification decreases with the increase in noninterest income. At the bank level, the correlation coefficients of the growth rates of net interest income and noninterest income are mostly negative, which also suggests that there are diversification benefits of increasing the noninterest income. However, further model analysis indicates that the effect of the noninterest income share on the Chinese banking industry's revenue and risk is not significant. Overall, our findings suggest that noninterest income diversifies bank revenue, but increased reliance on noninterest income may worsen the risk/return trade-off for the Chinese banking industry.     

Foreign Exchange Risk,Hedging, and Tax-Motivated Outbound Income Shifting

Although outbound income shifting to low-tax jurisdictions provides tax savings, it is often accompanied by nontax costs. In this study, I examine whether foreign exchange (FX) risk constrains tax-motivated outbound income shifting by U.S. multinational corporations. My findings indicate that exposure to greater currency volatility is associated with less outbound income shifting, and this effect is stronger for firms with foreign affiliates using foreign functional currencies. I also investigate whether hedging facilitates outbound income shifting. Consistent with hedging lowering costs associated with exchange rate volatility, I find that U.S. firms that use more currency derivatives tend to shift more income to low-tax foreign jurisdictions. Overall, these findings suggest that FX risk is an important cost of outbound income shifting.     

Usefulness of comprehensive income reporting in Canada

In January 2005 the Canadian Accounting Standards Board (AcSB) issued three new accounting standards that require Canadian firms to mark-to-market certain financial assets and liabilities and recognize the holding gains and losses related to these items as other comprehensive income or as part of net income. The Board’s objectives for issuing the new standards are (i) to harmonize Canadian GAAP with US and International GAAP, (ii) to enhance the transparency and usefulness of financial statements, and (iii) to keep pace with changes in accounting standards in other countries that are moving towards fair value accounting. This paper investigates empirically whether requiring Canadian companies to report comprehensive income and its components provides the securities market with incremental value-relevant information over the traditional historical-cost earnings approach.Previous empirical studies provide mixed evidence on the value relevance of other comprehensive income and its components. This mixed evidence may be attributed partially to the use of as if methodology to construct an ex-ante measure of other comprehensive income prior to the implementation of SFAS 130, which introduces measurement error. In contrast, this study uses actual data on other comprehensive income for a sample of Canadian firms cross-listed in the US in the period 1998–2003. We find evidence that available-for-sale and cash flow hedges components are significantly associated with price and market returns. We also find that aggregate comprehensive income is more strongly associated (in terms of explanatory power) with both stock price and returns compared to net income. However, we find that net income is a better predictor of future net income relative to comprehensive income. Our findings suggest that mandating all Canadian firms to adopt the new accounting standards is expected to enhance the usefulness of financial statements. Our findings, therefore, should be of interest to Canadian accounting policy makers as they provide ex-ante evidence on the potential usefulness of mandating firms to report comprehensive income and the components of other comprehensive income in their financial statements.     

On the Usefulness of Operating Income,Net Income and Comprehensive Income in Explaining Security Returns

This study evaluates the usefulness of three earnings definitions (operating income, net income and comprehensive income) in explaining residual security returns. Usefulness is measured in terms of relative information content and incremental information content. In the former, the goodness-of-fit of the return-earnings relationship is compared under each earnings definition. In the latter, the increase in goodness-of-fit due to additional earnings components is measured. Based on a sample that averages 922 firms a year for 18 years, the analysis shows that operating income weakly dominates net income, and that both operating income and net income dominate comprehensive income, in information content. The results also show that those items that account for the difference between net income and operating income have incremental information content, but not those between net income and comprehensive income. The practical and academic contributions of these findings are discussed.     

Precautionary saving and partially observed income

I propose an intertemporal precautionary saving model in which the agent's labor income is subject to (possibly correlated) shocks with different degrees of persistence and volatility. However, he only observes his total income, not individual components. I show that partial observability of individual components of income gives rise to additional precautionary saving due to estimation risk, the error associated with estimating individual components of income. This additional precautionary saving is higher, when estimation risk is greater. Compared with a precautionary agent who is otherwise identical, but ignores estimation risk, the rational agent consumes less at the beginning of his life, but consumes more later, because of larger wealth accumulated from savings for estimation risk. The utility cost of ignoring estimation risk is also quantified in closed form.     

Insider trading,stock return volatility,and the option market's pricing of the information content of insider trading

We find strong evidence that net insider selling is positively associated with future stock return volatility, consistent with insider selling increasing outside investors’ uncertainty. The positive effect of net insider selling is significantly stronger when the volatility is measured around the earnings announcement. Apparently, option prices do not fully reflect the information content of insider trading for future volatility. More specifically, we find no evidence that option traders adjust the implied volatility for the insider trading effect in a timely manner. Consequently, net insider selling is significantly associated with future option straddle returns and delta neutral returns.     

Banks’ earnings: Empirical evidence of the influence of economic and financial market factors

The structure of income is a foremost address within research on banks’ performance, especially with regard to effects on the resilience of banks’ earnings. Indeed, given their central position in the economy, banks shall thrive to generate sustainable earnings and control for their potential volatility. Existing studies mostly consider the weight of non‐net interest income (nonNII) as opposed to the traditional NII income source. Such aggregated nonNII is found to increase earnings risk but more granular studies conflict. We propose an original investigation of the influence of economic and financial conditions on various income types, assuming that performance may actually be driven by both the income structure and external conditions. We focus European banks, which have long been allowed to diversify beyond retail banking. Out of a straight panel framework, we question if the influence of external conditions spreads to earnings components other than credit losses and trading income and if it does allow for diversification benefits among components. We find that each component actually evolves owing to its own equation. Furthermore, effects of single variables may cumulate over different components of earnings (e.g. GDP) or provide with diversification benefits. These effects are all the more important since they are not mitigated by operating expenses. Hence, over a regarded period, banks’ performance depends upon their structure of income and upon volatilities and correlations of influential variables. Besides controlling for ex‐ante volatility, our approach shows that a given structure of income is not necessarily more resilient than others but that selected non‐banking income may support a higher stability of Earnings     

Dynamic connectedness and optimal hedging strategy among commodities and financial indices

This study looks at the best portfolio strategy for mitigating the risk associated with the MSCI ACWI & Frontier Markets Index, as well as the volatility spillovers between commodity markets and certain financial markets. Therefore, we empirically explore the connectedness among three financial indicators and five product groups using the framework of Diebold and Yilmaz (2012), which is based on a vector autoregressive process and variance decomposition of prediction errors, between 31 May 2002 and 30 July 2021. We also investigate the best hedging instrument(s) for the MSCI ACWI & Frontier Markets Global Index by combining the Asymmetric Dynamic Conditional Correlation (ADCC) model with the risk reduction index and the hedging ratios. Our empirical findings highlight the importance of volatility spillover effects across financial markets, which is not the case for commodity markets with low volatility externalities. Furthermore, the first markets appear to be net transmitters of volatility, whereas the second markets appear to be net receivers. Using the approach of Kroner and Sultan (1993), we show that the least risk portfolio is a portfolio that combines the MSCI ACWI & Frontier Markets Global Index with financial indices related to socially responsible and irresponsible investing.     

公允价值会计与市场投资异象研究——来自中国上市公司的经验证据

以2007～2010年我国A股公司为样本,研究了上市公司在采用公允价值计量方式后是否会产生新的投资异象以及造成这种投资异象的影响因素。运用均值T检验和Wilcoxon符号等级检验,并采用Fama-French三因素模型对样本公司进行回归。研究发现,在控制了市场风险、规模风险和账面市值比风险之后,投资策略仍然可获得超常回报率,并且公允价值变动损益占净利润比重大(小)的组,超常回报率低(高)。套利风险、交易成本是公允价值变动损益对净利润的波动性风险造成的投资异象的影响因素。交易成本越大,套利风险越高,错误定价越不容易被消除,其超常回报率也越高。     

Corporate derivatives use policy and information environment

We provide evidence consistent with the notion that prudent use of financial derivatives improves firms’ information environment. We show that firms with sophisticated and comprehensive derivatives use policies display lower levels of uncertainty about future cash flows, volatility of future income and sales growth, and equity mispricing than those that do not use derivatives. However, we also show that policies that consist of large positions in a single type of derivative contract are not likely to produce similar benefits. These results remain intact even after accounting for the endogenous nature of derivatives use policy and information risk and mispricing.     

Dynamic volatility spillover effects between oil and agricultural products

The strong volatility spillover between crude oil and agricultural commodity markets reduces the diversification benefits and implies costly risk management process faced by portfolio managers and agricultural producers. This paper proposes a comprehensive study of their dynamic implied volatility spillover effects after the global financial crisis 2008–2009, while considering the transition between oil volatility's regimes. By using implied volatility, our analysis emphasizes on the forward-looking information that market traders usually convey in making decisions. We employ the generalized spillover indices within a fractionally integrated VAR model to capture the dynamic patterns of the volatility spillover effects alongside the Markov Switching Autoregressive model to extract the regimes of oil. Our results show new evidence that the net volatility spillover effect from crude oil to all agricultural commodities tends to decrease when crude oil remains in its low volatility regime. Conversely, this effect experiences an increasing trend when crude oil remains in its relatively high volatility regime. A dynamic strategy that combines oil and the most balanced agricultural commodity in terms of volatility transmission with oil (i.e., close-to-zero net volatility spillovers) depending on oil's regimes consistently outperforms the buy and hold strategy in terms of information ratio.     

波动溢出网络视角的金融风险传染研究

当前各类经济风险交叉关联,金融系统的风险溢出效应备受关注,为刻画我国金融系统性风险传染的路径特征,本文从波动溢出网络的视角分析金融系统内部的风险传染机制。首先使用广义动态因子模型对收益波动的共同波动率成分和特质性波动率成分进行区分。然后,根据货币市场、资本市场、大宗商品交易市场、外汇市场、房地产市场和黄金市场之间的特质性波动溢出效应,利用基于TVP-VAR模型的方差分解溢出指数分析金融系统波动溢出的动态联动性和风险传递机制。在分析方向性波动溢出效应的基础上,采用方差分解网络方法构建起信息溢出复杂网络,从网络视角分析金融系统内部的风险传染特征。实证研究发现,房地产市场和外汇市场的净溢出效应绝对值相较于其他市场更大,其受其他市场风险冲击的影响强于对外风险溢出效应,而股票市场的单向对外风险溢出效应强度最大。在波动溢出的基础上,进一步考虑股市波动率指数与其他市场波动率指数进行投资组合的资产配置权重,计算了波动率指数投资组合的最优组合权重和对冲策略。研究结论有助于更好地理解我国金融系统的风险传染机制,对监管机构加强宏观审慎监管、投资者规避投资风险具有重要意义。     

Media sentiment and short stocks performance during a systemic crisis

During crisis periods, investors often engage in short selling of stocks, in line with their pessimistic view of the present and future market performance as well as with the hope to repurchase the stocks back in the future at much lower prices. This attitude not only affects stock returns, but also may lead to significant risk transmission among assets. Addressing this concern, our study examines the returns and volatility connectedness between media coverage index (MCI) and high short interest stocks during the recent Covid-19 pandemic. We document MCI as a net transmitter for all returns series, whereas the results for volatility series exhibits binary behavior, acting as either a transmitter or recipient depending on the considered sector of economic activity. We highlight that the healthcare and energy sector stocks behave as net recipients of both, returns and volatility; hence, a certain caution is required while including them in investment portfolios. Finally, the causality test indicates that the MCI is more strongly connected with stock returns than with volatilities, thus signaling that media, may not only provoke a rise in stock volatility, but cause intense risk transmission especially during a systemic crisis similar to Covid-19.     

Value Relevance of Comprehensive Income

In this paper, we investigate the value relevance of comprehensive income and its components for a sample of 92 New Zealand companies over the period 2003–2010. We find a stronger association of aggregate comprehensive income with stock price and market returns relative to net income. The change in the asset revaluation reserve and the change in fair value of available‐for‐sale securities drive this association. However, foreign currency translation and cash flow hedges are also associated with prices and returns.     

Identifying volatility risk premia from fixed income Asian options

Fixed income options are frequently adopted by companies to hedge interest rate risk. Their payoff dependence on the cumulative short-term rate makes them particularly informative about interest rate volatility risk. Based on a joint dataset of bonds and Asian interest rate options, we study the interrelations between bond and volatility risk premia in a major emerging fixed income market. We propose a dynamic term structure model that generates an incomplete market compatible with a preliminary empirical analysis of the dataset. Approximation formulas for at-the-money Asian option prices avoid the use of computationally intensive Fourier transform methods, allowing for an efficient implementation of the model. The model generates a bond risk premium strongly correlated with a widely accepted emerging market benchmark index (EMBI-Global), and a negative volatility risk premium, consistent with the use of Asian options as insurance in this market.     

Earnings Reported under IFRS Improve the Prediction of Future Cash Flows? Evidence from European Banks

This paper examines the relative costs and benefits of International Financial Reporting Standards (IFRS) adoption in the European Union by testing the ability of earnings computed under IFRS to predict future cash flows. The study considers the contribution of net income, comprehensive income and other comprehensive income to the usefulness of earnings to predict cash flows, and it compares IFRS with domestic Generally Accepted Accounting Principles (GAAP). Evidence from a sample of Continental European banks shows that IFRS improve the ability of net income to predict future cash flows. Comprehensive income, too, provides relevant information to predict future cash flows, although with a measurement error which is higher than that in net income for greater lags of time. In our interpretation, these findings are consistent with unrealised gains and losses recognised in other comprehensive income being more transitory and volatile in nature. Overall, our results are relevant to academics and standard setters debating the merits of IFRS adoption and to those who use financial statements and adopt reported earnings to form expectations about future cash flows.
