The alchemy of CDO credit ratings

Collateralized loan obligations (CLOs) were one of the largest and fastest growing segments of the structured finance market, fueling the 2003-2007 boom in syndicated loans and leveraged buyouts. The credit crisis brought CLO issuance to a halt, and as a result the leveraged loan market dried up. Similar to other structured finance products, investors in CLOs rely heavily on credit rating provided by the rating agencies, yet little is known about CLO rating practices. This paper attempts to fill the gap. Using novel hand-collected data on 3912 tranches of collateralized loan obligations we document the rating practices of CLOs and analyze their structures.     

Active loan trading

Using a novel dataset of leveraged loan trades executed by managers of collateralized loan obligations (CLOs), we document the importance of “active loan trades” – trades executed at a manager’s discretion. More active trading increases the returns to CLO equity investors, lowers collateral portfolio default rates, and increases the manager’s chances of closing a new deal. Examining the observed loan trades, we find that more active CLOs trade at better prices than less active CLOs, selling leveraged loans earlier and before they get downgraded. Our findings suggest that more active CLOs are better at anticipating deteriorations in loan credit quality.     

The anatomy of corporate securitizations and contract design

Collateralized loan obligations (CLOs), intermediaries situated between investors and traditional banks, play an increasingly central role in the provision of credit to constrained corporations, holding as much as 75% of all new institutional leveraged loans. Despite their ascendancy in the risky corporate credit market, there has been little academic research on the CLO market. This paper provides a comprehensive overview of the design and structure of the CLO market, describing the general macroeconomic milieu that has facilitated the rapid growth of the market, the mechanics therein, as well as recent risks that have emerged. Understanding the anatomy and dynamics of CLOs is paramount for developing insights into the role of non-bank financial intermediaries in financial markets.     

Portfolio performance manipulation in collateralized loan obligations

We examine the discretionary activities that CLO managers engage in to pass monthly overcollateralization (OC) tests. These tests require a CLO's loan portfolio value, scaled by the CLO notes’ principal balance, to be above a certain threshold. Using CLOs’ granular disclosures, we develop model-free estimates for discretionary loan fair valuation and transaction-based proxies for strategic loan trading. We find a positive association between these discretionary activities and the probability of avoiding an OC test violation. This association varies predictably with junior noteholders’ influence and CLO market conditions. Strategic trading—but not discretionary fair valuation—relates to worse future CLO performance.     

CLO trading and collateral manager bank affiliation

This paper investigates whether the institutional affiliation of a collateralized loan obligation (CLO) manager influences the manager's access to information and risk appetite. We find that CLO managers affiliated with banks start to sell off their positions in loans arranged by their bank well before the onset of default. In contrast, CLO managers affiliated with nonbanks do not lower their exposures to distressed loans. These findings are consistent with bank-affiliated CLO managers being more risk averse, but they could also derive from them having access to valuable information. On close inspection, we find that although bank-affiliated CLO managers are averse to holding any distressed loans, they are also more aggressive at divesting distressed loans arranged by their parent bank, suggesting that they benefit from an information wedge. Besides helping us understand CLO managers’ trading activities, our findings highlight a potential limit to banks’ ability to originate loans and distribute them via their affiliated CLOs.     

Underwriter reputation and the pricing of securities: Evidence from asset-backed securities

This paper investigates whether and how the underwriter reputation can affect the pricing of securities. Using data on collateralized loan obligations (CLO), asset-backed securities (ABS), and asset-backed medium-term notes (ABN) from 2014 to 2019 in China bond market, we find that the underwriter's reputation has a significantly negative impact on the issuance spread. This effect is more pronounced in the CLO and ABS markets, while that in the ABN market is not significant. Furthermore, we find that the originators play a critical role in determining the issuance spread of securities, as state-owned and listed originator receive a lower initial yield spread. In addition, the number of tranches and the proportion of subordination in a deal also have a stronger effect on the relation between which the underwriters' reputation and securities prices. These results suggest that underwriters play a role in reducing information asymmetry between originators and investors, which is partly corrected via underwriter reputation.

The Equity Share in New Issues and Aggregate Stock Returns

The share of equity issues in total new equity and debt issues is a strong predictor of U.S. stock market returns between 1928 and 1997. In particular, firms issue relatively more equity than debt just before periods of low market returns. The equity share in new issues has stable predictive power in both halves of the sample period and after controlling for other known predictors. We do not find support for efficient market explanations of the results. Instead, the fact that the equity share sometimes predicts significantly negative market returns suggests inefficiency and that firms time the market component of their returns when issuing securities.     

On the relationship between exchange rates and equity returns: A new approach

This paper employs a new approach in order to investigate the underlying relationship between stock markets and exchange rates. Current approaches suggest that the relative equity market performance of two countries is linked to their exchange rate. In contrast, this study proposes an alternative approach where one global variable – global equity market returns – is believed to have an effect on exchange rates, with the relative interest rate level of a currency determining the sign of the relationship. Our empirical findings suggest that exchange rates and global stock market returns are strongly linked. The value of currencies with higher interest rates is positively related with global equity returns, whereas the value of currencies with lower interest rates is negatively related with global equity returns.     

Securitization without adverse selection: The case of CLOs

In this paper, we investigate whether securitization was associated with risky lending in the corporate loan market by examining the performance of individual loans held by collateralized loan obligations. We employ two different data sets that identify loan holdings for a large set of CLOs and find that adverse selection problems in corporate loan securitizations are less severe than commonly believed. Using a battery of performance tests, we find that loans securitized before 2005 performed no worse than comparable unsecuritized loans originated by the same bank. Even loans originated by the bank that acts as the CLO underwriter do not show under-performance relative to the rest of the CLO portfolio. While some evidence exists of under-performance for securitized loans originated between 2005 and 2007, it is not consistent across samples, performance measures, and horizons. Overall, we argue that the securitization of corporate loans is fundamentally different from securitization of other assets classes because securitized loans are fractions of syndicated loans. Therefore, mechanisms used to align incentives in a lending syndicate are likely to reduce adverse selection in the choice of CLO collateral.     

International order flows: Explaining equity and exchange rate returns

Macroeconomic models of equity and exchange rate returns perform poorly at high frequencies. The proportion of daily returns that these models explain is essentially zero. Instead of relying on macroeconomic determinants, we model equity price and exchange rate behavior based on a concept from microstructure–order flow. The international order flows are derived from belief changes of different investor groups in a two-country setting. We obtain a structural relationship between equity returns, exchange rate returns and their relationship to home and foreign equity market order flow. To test the model we construct daily aggregate order flow data from 800 million equity trades in the U.S. and France from 1999 to 2003. Almost 60% of the daily returns in the S&P100 index are explained jointly by exchange rate returns and aggregate order flows in both markets. As predicted by the model, daily exchange rate returns and order flow into the French market have significant incremental explanatory power for the daily S&P returns. The model implications are also validated for intraday returns.     

Can Managers Forecast Aggregate Market Returns?

Previous studies have found that the proportion of equity in total new debt and equity issues is negatively correlated with future equity market returns. Researchers have interpreted this finding as evidence that corporate managers are able to predict the systematic component of their stock returns and to issue equity when the market is overvalued. In this article we show that the predictive power of the share of equity in total new issues stems from pseudo‐market timing and not from any abnormal ability of managers to time the equity markets.     

The relationship between aggregate managed fund flows and share market returns in Australia

This paper presents the relation between aggregate equity managed fund flows and excess share market returns in Australia and evaluates the issue of causality therein. Using a large data set of 3613 managed funds for the period January 1990 to September 2009, the paper addresses two important questions yet to be addressed within the Australian market: First, for research question one; it aims to determine whether a positive feedback process exists between aggregate equity managed fund flows and excess share market returns. Second, for research question two; it examines the relation between unexpected aggregate equity managed fund flows and excess share market returns. The empirical findings contribute to the literature by confirming, in Australia, aggregate equity managed fund flows do not Granger-cause excess share market returns; however, compelling evidence reveals that share market returns do in fact Granger-cause managed fund flows. These findings support those of Edwards and Zhang (1998), who find similar evidence for the United States over the sample period 1961–1996. In addition, aggregate equity managed fund flows are found to be positively related to excess share market returns, indicating herding behavior.     

Corporate Loan Securitization and the Standardization of Financial Covenants

We examine whether syndicated loans securitized through collateralized loan obligations (CLOs) have more standardized financial covenants. We proxy for the standardization of covenants using the textual similarity of their contractual definitions. We find that securitized loans are associated with higher covenant standardization than nonsecuritized institutional loans. In addition, we show that CLOs with more diverse or frequently rebalanced portfolios are more likely to purchase loans with standardized covenants, potentially because standardization alleviates information processing costs related to loan monitoring and screening. We also document that covenant standardization is associated with greater loan and CLO note rating agreement between credit rating agencies, further supporting the relation between lower information costs and covenant standardization. Overall, our study provides evidence that loan securitization is related to the design of standardized financial covenants.     

Alternative Methods for Projecting Equity Returns: Implications for Evaluating Social Security Reform Proposals

The effect upon future Social Security benefits resulting from the introduction of individual accounts depends on both the potential risks and returns of private equities, yet the historical evidence about the determinants of stock market risks and returns is mixed. In particular, correlations between equity returns and market fundamentals (such as the dividend–price ratio) are weak at annual frequencies, which has led some to conclude that a random returns (fixed mean and variance) model is the preferred specification for simulating the future path of equity returns. Although choosing between the random returns model and models based on market fundamentals does equally well for explaining variation of equity returns in the short run, the distinction is important when projecting equity returns over longer periods, as shown here in the context of a Monte Carlo simulation of Social Security reform. If equity returns are even weakly correlated with market fundamentals then (1) the expected future average return may be a function of the starting values for market fundamentals, and (2) the overall range of cumulative outcomes is narrower than the random returns model suggests.     

Nonfinancial Firms as Cross‐Market Arbitrageurs

I demonstrate that nonfinancial corporations act as cross‐market arbitrageurs in their own securities. Firms use one type of security to replace another in response to shifts in relative valuations, inducing negatively correlated financing flows in different markets. Net equity repurchases and net debt issuance both increase when expected excess returns on debt are particularly low, or when expected excess returns on equity are relatively high. Credit valuations affect equity financing as much as equity valuations do, and vice versa. Cross‐market corporate arbitrage is most prevalent among large, unconstrained firms, and helps account for aggregate financing patterns.     

Does Securitization of Corporate Loans Lead to Riskier Lending?

This paper finds that loans sold to collateralized loan obligations (CLOs) underperform matched unsecuritized loans originated by the same bank. We find that banks put less weight on the hard information on borrower risk available to them when they set interest rates on the loans they sell to CLOs, and that they retain less skin in the game on these loans, suggesting that lax underwriting standards contributed to the worse performance of securitized loans. We also find that the median non‐CLO syndicate participant retains a lower stake in securitized loans when compared to loans that are not securitized, suggesting that these investors, like lead banks, expected securitized loans to perform worse.     

Asymmetry in return and volatility spillover between equity and bond markets in Australia

We document asymmetry in return and volatility spillover between equity and bond markets in Australia for daily returns during the period 1992–2006 using a bivariate GARCH modelling approach. Negative bond market returns spillover into lower stock market returns whereas good news originating in the equity market leads to lower bond returns. Bond market volatility spills over into the equity market but the reverse is not true. Transmission of bond volatility into equity volatility depends in a complex way upon the respective signs of the return shocks in each market.     

Equity returns,bond returns,and the equity premium in the German capital market

This article reviews the empirical evidence for equity returns, bond returns, and the equity premium in the German capital market for the period from 1870 to 1995. Taken together, the studies reviewed provide convincing evidence that over longer investment periods, average equity returns have been higher than average bond returns. These excess returns, however, have been highly volatile and negative in many years, illustrating the higher risk of equity investments. Moreover, market timing had a major positive or negative impact on overall returns. Despite the historical evidence of a substantial equity premium there is still little equity investment by German households.     

Equity Capital Flows and Demand for REITs

REITs are attractive to investors due to their unique characteristics such as high dividend yields, low correlation with common stocks, and a potential hedge against inflation. Thus the market demand curve of REIT equities may not be horizontal. This paper examines the shape of the market demand curve for REIT equities by employing REIT equity capital flows as a proxy for REIT aggregate demand. Our results do not support a downward demand curve for REIT equities. That is, we do not find evidence for the price-pressure effect in REIT returns. Instead, we find it is REIT returns that affect REIT equity capital flows rather than REIT equity flows that affect REIT returns. The results are consistent when we allow for the presence of market fundamental variables in our analysis. In addition, a variance decomposition analysis suggests that REIT equity capital flows do not cause revisions in expected cash flows (dividends) that are strong enough to impact REIT returns. Thus our findings are consistent with implications that the market demand curve for REIT equities is horizontal.
