Disentangling Beta and Value Premium Using Macroeconomic Risk Factors

In this paper, we study the time-varying total risk of value and growth stocks. The objective is to investigate the contention that the market factor's ability to explain the value premium is limited. Inspired by Ferson and Harvey [1999], we revisit the role of the market beta in the presence of aggregate economic factors. We discuss the incorporation of aggregate economic conditions in the context of multifactor risk models and provide cross-sectional evidence on the relationship between average returns and postranking betas for book-to-market (BE/ME) sorted portfolios. We show that the ineffective role of the market beta can be altered by incorporating aggregate economic risk factors in the cross-sectional asset pricing tests of size and BE/ME sorted portfolios. No previous study provides such a decomposition of the cross-sectional role of the market beta in the presence of macroeconomic risk factors.     

Options on bond futures: Isolating the risk premium

The introduction of unspanned sources of risk (and frictions) implies that option prices include a risk premium. Prima facie evidence of the existence of risk premia in option prices is contained in the implied volatility smile patterns reported in the literature. This article isolates the risk premium (defined as the simple difference between estimated and observed option prices) on options on U.K. Gilts, German Bunds, and U.S. Treasury bond futures using models that include price jumps and stochastic volatility. This study finds that single and multi‐factor stochastic volatility models with jumps may explain the empirical regularities observed in bond futures. © 2003 Wiley Periodicals, Inc.

Does a sustainability risk premium exist where it matters the most?

Using a sample of ESG ratings, we examine the sustainability risk premium for developed and emerging markets between 2015 and 2019-end. Our results show that this premium is not empirically distinguishable in developed equity markets, whilst highly positive in the emerging ones. We further partition the emerging markets to comprehend whether country development and firm size have an impact on the sustainability risk premium. As uncovered, both factors play a significant role in the emergence of the risk premium. Consequently, larger corporations and advanced nations drive sustainability in the emerging markets and thus experience the financial benefits.     

What explains default risk premium during the financial crisis? Evidence from Japan

As is well documented, subprime mortgage markets carried significant default risk. This paper investigates the relationship between default risk premium, stock market conditions and macroeconomic variables during the financial crisis. Using iTraxx Japan Credit Default Swap (CDS) index spreads covering the period from March 2006 to November 2009, we employ a time-varying dynamic factor model with Markov regime switching to generate regime probabilities for default risk. We analyze the sensitivity of default risk premium changes to stock market conditions and macroeconomic variables by using two-state Markov switching models: a crisis regime sparked by rising loan defaults in the sub-prime mortgage market, and a non-crisis regime. We found strong evidence that the relationship between default risk premium changes, stock market and macroeconomic variables is regime-dependent. Our results suggest that during periods of crisis, CDS indices behave as a higher-risk indicator and become more sensitive to stock market conditions and macroeconomic variables. This paper examines the effects of the financial crisis in explaining the default risk premium. Understanding the determinants of default risk premium is important for financial analysts, economic policy makers and credit risk management.     

Risk premia in forward exchange rates: systematic or unsystematic?

International traders frequently use forward exchange transactions to hedge their cash flows in foreign currencies. A key issue is whether the forward rates are efficiently priced. There is evidence of time-varying risk premia in forward exchange rates. Are these risk premia systematic or unsystematic? This article uses a market model to explain risk, implying that the risk premium in the forward rate varies pari passu with the beta of the return to speculative forward positions. Assuming the unobserved risk premium is proportional to the forward premium allows testing the predicted relations; the data reject the joint hypotheses of the model and systematic risk. In terms of a simple factor model explaining the covariation of the forward premium, the risk premium, and the expected percentage rate of change of the spot exchange rate, the assumption that the forward premium and the risk premium are proportional can be relaxed without changing the empirical results.     

Risk premiums and predictive ability of BAX futures

This study provides an in‐depth analysis of risk premiums in the Canadian Bankers' Acceptances futures (BAX) market. The predictive regressions for excess and holding‐period returns on BAX futures lend empirical support to the presence of time‐varying risk premiums especially at longer horizons. Despite the evidence of time variation in the risk premium, however, the unbiasedness of the basis as a predictor of spot returns in forecast efficiency regressions cannot be rejected. The out‐of‐sample forecasts of spot returns demonstrate the excellent predictive ability of models that exploit the restrictions implied by the unbiasedness hypothesis. Overall, our findings support the presence of a slowly moving risk premium and entail important practical implications for measuring monetary policy expectations and portfolio allocation. © 2010 Wiley Periodicals, Inc.

Market Timing With Moving Averages

I present evidence that a moving average (MA) trading strategy has a greater average return and skewness as well as a lower variance compared to buying and holding the underlying asset using monthly returns of value‐weighted US decile portfolios sorted by market size, book‐to‐market, and momentum, and seven international markets as well as 18,000 individual US stocks. The MA strategy generates risk‐adjusted returns of 3–7% per year after transaction costs. The performance of the MA strategy is driven largely by the volatility of stock returns and resembles the payoffs of an at‐the‐money protective put on the underlying buy‐and‐hold return. Conditional factor models with macroeconomic variables, especially the default premium, can explain some of the abnormal returns. Standard market timing tests reveal ample evidence regarding the timing ability of the MA strategy.     

Certainty equivalent,risk premium and asset pricing

This paper attempts to determine the certainty equivalent of an uncertain future cash flow or value through the option pricing method, and builds models of certainty equivalent and certainty equivalent coefficient. Based on the model of certainty equivalent coefficient, this paper further derives models of risk premium and risk-adjusted discount rate. The latter is a new capital asset pricing model (CAPM) accounting for total risk rather than with only the systematic risk accounted for as in the current CAPM. The reliability in relevant financial analysis, valuation, decision making and risk management may be enhanced with these new models.     

How Does Legitimacy Operate in Emerging Capital Markets? Investigating the Moderating Effects of Premium Listings and Firm Size on Risk

Drawing on an institutional theoretical perspective, we investigate the impact of the origins of organizational legitimacy on systematic risk using a sample of 358 Brazilian companies between the years 2002 and 2007. We regard three origins of legitimacy—formal–regulatory (presence in premium listings), cultural–cognitive (board of directors), and normative legitimacy (reputation)—to empirically investigate how a company's size and adherence to premium lists moderate other sources of legitimacy. Our results indicate that only under apparently better quality corporate governance conditions—presence in premium listings—do corporate reputation and the board of directors reduce systematic risk. In addition, we show that the effect of reputation on risk is positively moderated by firm size. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

Trade effects of the Europe agreements: A theory-based gravity approach

We analyze normalized productivity differences for 15 developing Latin American countries and four firm types: National Domestic, National Exporter, Foreign Domestic, and Foreign Exporter. There are no productivity thresholds for viability, export activity, or multinational activity, but we do find a clear size productivity premium and development productivity premium in the manufacturing sectors. We also find a clear foreign-ownership productivity premium, both for domestic firms and for exporting firms and both for manufacturing sectors and services sectors. In contrast, we only find an export productivity premium for national firms in the manufacturing sectors.     

The cross-section of returns in frontier equity markets: Integrated or segmented pricing?

Is asset pricing segmented or integrated in frontier equity markets? To answer this question, we examine the returns on more than 4500 stocks from 22 frontier countries for the years 1997–2018. We evaluate the performance of a few major asset pricing models. We document strong value and momentum effects but find no consistent evidence regarding size, investment, and profitability premia. The recent six-factor model of Fama and French (2018) outperforms other models and best explains the cross-sectional and time-series variation in returns. Our results point to low integration of frontier equities, even after the global financial crisis. Local risk factors explain the behavior of prices much better than their global counterparts do. The low correlation of these risk factors allows augmenting the efficient frontier of an international investor.     

Effect of climate-related risk on the costs of bank loans: Evidence from syndicated loan markets in emerging economies

Based on a novel dataset that combined syndicated loans originated in the emerging market economies with greenhouse gas emission intensity data of borrowers, this study examines whether and to what extent banks in these emerging markets have factored in climate transition risk in their lending decisions. On loan pricing, our results suggest that banks in these emerging markets have started to price-in climate transition risk for loans to emissions-intensive sector since the Paris Agreement. This could reflect their increased awareness of a climate-transition risk towards such firms. The extent of the transition risk premium is also found to be dependent on the environmental attitude of banks. Specifically, green banks are found to charge a higher loan spread than other banks, when lending to the same brown firm after the Paris Agreement. Apart from pricing a transition risk premium in the loan spread, we find evidence that banks may also consider imposing more stringent non-pricing contractual terms, such as shortening loan tenor and imposing collateral requirement, on brown firms especially when the associated credit risk impacts on these firms are more uncertain.     

An analysis of illiquidity in commodity markets

We examine the liquidity and insurance premia demanded by hedgers and speculators in commodity markets. We find that hedgers and speculators demand a higher premium for illiquid commodities for providing insurance and liquidity, respectively. Decomposing illiquidity into turnover and size components, we find evidence of a size premium associated with the insurance premium such that speculators demand a larger insurance premium for smaller commodities. We also find that the liquidity premium demanded by hedgers for illiquid commodities varies across bullish and bearish markets with hedgers demanding a larger premium from speculators trading in illiquid commodities in bearish markets.     

Risk and Return in the 20th and 21st Centuries

The single most important contemporary issue in finance is the equity risk premium. This drives future equity returns, and is the key determinant of the cost of capital. The risk premium – the expected reward for bearing the risk of investing in equities, rather than in low-risk investments such as bills or bonds – is usually estimated from historical data. This article starts by summarising new evidence on historical returns in twelve major world markets from the authors' recent book, 'The Millennium Book: A Century of Investment Returns'. The authors show that the historical equity risk premium has been lower than previously believed, and argue that the future risk premium is likely to be lower still. They discuss what this implies for the cost of capital, stock market values, and companies' target rates of return. They suggest that many companies are seeking too high a rate of return and thus run the risk of under-investing.     

Regulatory procedures,investment opportunities and stock valuation

Electric utilities differ in their accounting procedures. By regulatory commission directive some use normalization and some use flow through to arrive at their earnings figures. Because regulation is on an allowed return on investment standard these reported earnings are relevant for stock valuation. Any variation in price/earnings ratios between flow through and normalizing companies therefore must be explained by differences in risk to equity investors, differences in investment opportunities, or market inefficiency involving erroneous restatement of earnings. Empirical work demonstrates that there is a difference in price/earnings ratios. Firms that normalize enjoy a premium. The evidence also indicates that the premium is not explained by risk difference. Because the perverse form of market inefficiency required as an explanation seems unlikely, the most reasonable conclusion is that the premium relates to investment opportunities associated with regulatory climate. If so it promises no excess return to stock buyers because it is already impounded in stock price.

Exchange risk premia and firm characteristics

This paper examines the presence and the determinants of exchange risk premia in stock returns using firm level data from South Korea. We conduct empirical asset pricing tests based on cross-sectional data sorted by firm characteristics such as firm size, liquidity, foreign ownership, and industry. Using alternative model specifications and exchange rate measures, our results support the hypothesis of a significant unconditional exchange risk premium in the Korean stock market at firm and industry levels. More specifically, we find that the exchange risk premium is directly related to firm liquidity and inversely related to firm size and foreign ownership.     

Normal backwardation is normal

Traditionally, constant expected return asset pricing models are used to assess the presence of a futures risk premium and the validity of the normal backwardation theory. In the light of recent evidence regarding the presence of time variation in expected futures returns, such an approach may lead to incorrect inferences on the applicability of the Keynesian hypothesis. This article therefore allows for variation through time in expected futures returns and offers some strong evidence in favor of the normal backwardation and contango theories. © 2000 John Wiley & Sons, Inc.

新冠肺炎疫情后各国主权债务风险及其前景

新冠肺炎疫情及其经济冲击促使许多国家财政赤字率和政府债务率大幅升高,其影响程度超过了2008年国际金融危机。笔者既不赞成现代货币理论(MMT)的看法,也不认同悲观派的看法。从影响各国主权债务风险的几大因素看,一些新兴市场经济体尤其需要关注利率的3种风险溢价:通胀风险溢价、货币贬值风险溢价和信誉(违约风险)溢价。展望未来,发达经济体和新兴市场经济体将花费数年时间进行财政收支和政府债务调整,以渐进方式推进政府部门的去杠杆。     

Size, value and liquidity. Do They Really Matter on an Emerging Stock Market?

The paper extends the evidence on factors determining stock prices on emerging markets by focusing on the most advanced stock market in Central and Eastern Europe, the Polish market. Besides market, size and value factors, we investigate whether liquidity is a priced risk factor, addressing the hypothesis of its particular relevance in emerging markets. Our results support existing evidence for developed markets regarding market, size, and value factors. Contrary to the expectation that liquidity is a priced factor on emerging markets, we do not find evidence supporting this hypothesis. Analyzing specific market characteristics, we consider possible explanations behind these findings.
