Diversification,corporate governance and firm value in small markets: evidence from New Zealand

We find that diversified firms in New Zealand are associated with a value discount of 19–42 per cent relative to single‐segment (undiversified) firms. Although several competing explanations have been offered in the literature, we find that the strength of corporate governance explains between 15–21 per cent of this discount. Specifically, board size, busyness of directors, CEO ownership and whether or not compensation of directors includes equity‐based components collectively explain a large part of the reported discount. Our results from companies trading in New Zealand complement recent findings in the US by not only confirming the existence of a diversification discount but also emphasizing the role of poor governance in destroying shareholder wealth by pursuing a value‐destroying corporate strategy. All our results hold after controlling for potential endogeneity in the decision to diversify and the choice of corporate governance structure by employing two‐way fixed‐effects and dynamic‐panel generalized method of moments regression techniques.     

Income Diversification and Bank Performance: Evidence from Italian Banks

Using annual data from Italian banks, we study the link between non-interest revenues and profitability. We find that income diversification increases risk-adjusted returns. Our results provide econometric evidence consistent with current studies on EU banks, but do not support findings on the U.S. experience. In our view, the differences depend primarily on the relative importance of local banks: we find that the relation is stronger at large banks. In addition, we find that there are limits to diversification gains as banks get larger. Small banks can make gains from increasing non-interest income, but only when they have very little non-interest income share to start with. The source of non-interest income is less important than its level.

Noise-trading, costly arbitrage, and asset prices: Evidence from US closed-end funds

The behavior of US closed-end funds is very different from that of UK funds. There is no evidence that the US funds' discounts are constrained by arbitrage barriers, no evidence that higher expenses increase discounts and no evidence that replication risk increases discounts but strong evidence that noise-trader risk is priced. The differences between US and UK funds may be due to the fact that small investors dominate US funds while institutional investors dominate UK funds, or because the sample selection method for the UK funds chooses only funds that are relatively easy to arbitrage.     

Asset allocation and portfolio performance: Evidence from university endowment funds

We use university endowment funds to study the relationship between asset allocation decisions and performance in multiple asset class portfolios. Although endowments differ substantially in asset class composition, policy portfolio returns and volatilities are remarkably similar across the sample. The risk-adjusted performance of the average endowment is negligible, but actively managed funds generate significantly larger alphas than passive ones. This is consistent with endowment managers exploiting their security selection abilities by over-weighting asset classes in which they have superior skills. Contrary to both theory and prevailing beliefs, asset allocation is not related to portfolio returns in the cross-section but does indirectly influence performance.     

Monetary policy and portfolio rebalancing: Evidence from European equity mutual funds

In this study, we provide empirical evidence on the portfolio rebalancing of European equity mutual funds following both conventional (CMP) and unconventional monetary policies (UMP). We use 1772 equity mutual funds’ portfolio holdings over the period 2002Q4–2016Q4. This level of granularity allows us to characterise the funds’ asset allocation in different portfolio dimensions: the size, style, currency, and domicile of the stocks, and managers’ preferred investment strategies. Using a panel fixed effect estimator, our results support the existence of portfolio rebalancing across equity categories following UMP. European equity mutual funds’ assets are, on average, reallocated towards mid-cap, and core stocks and developing economies, and shifted away from small-cap and value stocks and home as well as developed countries. Furthermore, mutual funds seem to concentrate on their preferred and historical investment strategies. These two results suggest that managers are more willing to invest in safer and familiar stocks following UMP announcements thereby decreasing the risk of asymmetry of information. We finally show that the funds size, returns volatility and expense ratio affect the strength of the rebalancing.     

On the concentration of mutual fund portfolio holdings: Evidence from Taiwan

This paper tests the alternative hypotheses of investment selection skills versus overconfidence of equity mutual funds managers in Taiwan. We find that fund holdings’ concentration levels are high and positively related to funds’ risk-adjusted returns in tranquil market periods; however, the concentration levels are low and more negatively related to risk-adjusted returns in turmoil market periods. The time varying concentration-performance relation is not driven by fund size. Our finding implies that fund managers have superior investment selection skills when the market is less volatile, but they exhibit overconfidence when the market is in turmoil, suggesting an investment strategy of shifting from concentrated funds to more broadly diversified funds when market condition becomes worse.     

Pension funds and IPO pricing. Evidence from a quasi-experiment

We exploit a quasi-experiment arising from the government-forced changes to the assets under management and investment policy of the Polish pension funds. We test whether this new regulation and its resultant demand shock on the investors' side, leads to changes in the IPO pricing and the subsequent stock's performance. We report material and a statistically significant decrease in the IPO proceeds (IPO size) in the post-treatment period equal to over 107 million PLN (34 million USD). We find no empirical evidence that the treatment had a significant effect on the first-day IPO underpricing or on the long-term underperformance. We conclude that the demand shock resulting from the pension system reform that primarily aimed at solving fiscal problems effectively eliminated the so-called ‘pension premium’ of higher IPO valuations. Thus, it indirectly impaired companies' power of raising money in the public stock market. Furthermore, we report a decrease in the average first-day IPO returns among big issuers that is consistent with the book building literature.     

Entrepreneurship and household portfolio choice: Evidence from the China Household Finance Survey

The efficient allocation of household assets is important for household wealth and entrepreneurial activities. However, there is scarce evidence on how entrepreneurial activities influence household financial decisions. We use a simple model to characterize the impact of entrepreneurship on household portfolio choice and the two underlying channels—the diversification effect and the risk substitution effect. We also empirically examine the impact of entrepreneurship using data from the 2013, 2015, and 2017 waves of the China Household Finance Survey (CHFS). The empirical results show that entrepreneurship significantly decreases both household risky market participation and risky asset holding. These findings are robust to alternative measurements of key variables, different model specifications, and Lewbel’s two-stage estimators. This study also verifies the co-existence of both the diversification and risk substitution effects. In particular, the net effect of entrepreneurship on household portfolio choice varies between urban and rural areas due to the different offsetting results between the two effects.     

Bank Diversification and Overall Financial Strength: International Evidence

There are many studies in the finance and management literature that examine the impact of diversification on performance. Yet, the literature remains inconclusive as for the potential benefits in terms of risk and return. The present study aims to re‐examine this issue, while proposing a methodological framework that integrates various bank performance and risk indicators into a single measure of financial strength. Using an international sample of commercial banks, we find that diversification in terms of income, earning assets, and on‐ and off‐balance sheet activities influences positively their financial strength. We also find that income diversification can be more beneficial for banks operating in less developed countries compared to banks in advanced and major advanced economies. However, we observe the opposite in the case of diversification between off‐balance sheet and on‐balance sheet activities. Furthermore, the results reveal that income and earning assets diversification can mitigate the adverse effect of the financial crisis on bank financial strength. We continue to find a positive relationship between diversification and financial strength when we account for nesting effects, endogeneity, as well as when using an alternative approach for the construction of the financial strength indicator.     

Discount rates for long-term projects: the cost of capital and social discount rate compared

Research on the cost of capital and on the social discount rate (SDR) has developed largely along separate paths. This paper offers an overview and comparison of both concepts. The consumption-based theory of discount rates is common to both, but there are striking differences in how the cost of capital and SDR are estimated. A project's cost of capital is inferred in practice from market data, by a well-established package of techniques, and project risk makes a large difference. In contrast, the SDR is estimated by applying judgement about the welfare of future generations, in the setting of consumption-based theory. Project risk has tended to be ignored under the SDR approach.     

The information content of portfolio performance history and persistence in fund performance: An examination of rollover funds

This paper examines the relation between past and future performance and explores the optimal past performance information set for a subset of Australian investment funds, namely, rollover funds. Four categories of funds are examined: fixed interest; multi-sector yield; multi-sector balanced; and multi-sector growth. This study extends the performance persistence literature through the use of three methodologies (1) regression analysis;(2) non-parametric contingency tables; and (3) top (and bottom) quartile rankings to explore the information content of fund performance history for groups of funds differentiated by investment objective. The results of the regression analysis suggest that there is evidence in support of persistence in performance for the fixed interest funds (particularly when performance is measured in terms of Jensen Alpha) but much more ambiguous evidence in relation to the multi-sector funds. Contingency table analysis of fund performance histories of varying lengths reveals quite different results depending upon whether raw or risk-adjusted returns are used. Use of raw returns creates an overall impression of performance reversals, whereas use of risk-adjusted returns suggests the existence of performance persistence. Finally, the use of prior period top-quartile and bottom-quartile ranking are found to show strong evidence of persistence in respect to the risk-adjusted performance of fixed-interest funds.     

Governance and Performance Implications of Diversification Strategies: Evidence from Large U.S. Firms

Recent research focuses on explaining the diversification discount. However, there is little direct evidence regarding the relation among ownership structure, corporate governance, and corporate diversification. The results in this paper suggest that agency issues do not account for firms adopting a particular diversification strategy. Also, the performance consequences of the shift in the diversification strategy and the subsequent changes in institutional and block ownership structures are not related to agency issues. In fact, investors seem not to avoid diversified firms per se. We suggest that observed board and ownership differences between diversified and focused firms are due to their being at different stages of corporate evolution.     

The Sensitivity of Individual and Institutional Investors' Expectations to Changing Market Conditions: Evidence from Closed-End Funds

This study investigates whether individual and institutional investors respond differently to changes in market conditions. Closed-end funds are the medium used to test the hypothesis because closed-end fund shares (held primarily by individual investors) and the underlying assets (held primarily by institutional investors) are claims to the same stream of distributions. The empirical results suggest that individual investors are more responsive than institutional investors to changes in market conditions. Moreover, although the response of institutional investors differs across stock and bond markets, we cannot reject the hypothesis that the additional sensitivity of individual investors' expectations is uniform across stock and bond markets.     

Diversification strategy,efficiency, and firm performance: Insight from emerging market

We investigate further the inconsistencies of the diversification-performance link by introducing efficiency as moderating factor. A data of 319 firms was used to conduct a panel data analysis excluding the financial sector industries and the results show three important findings. First, industrial diversification shows a significant contribution in performance improvement while international diversification shows no effect on performance. Yet, international-conglomerate shows a significant negative relationship with performance. Meanwhile, the efficiency results are contrary to our conjecture. We find that efficiency is a factor to enhance performance, but it is not the moderating variable on the diversification-performance link. This implies that the efficiency of the firm has no connection with the link between diversification and performance.

Performance Manipulation and Fund Flow: Evidence from China

In this paper, we assess the relation between fund flow and fund returns in China's open-ended fund industry. Analyzing quarterly data from the period January 2005-December 2012, we construct a simultaneous equation model that captures the endogeneity of current and past returns and flows and find that contemporaneous returns have a key role in determining fund flows. We then estimate the fund performance "manipulation degree" to further investigate the performance manipulation effect on fund flows. We find that manipulated funds can attract an additional flow of money and that, notably, individual rather than institutional investors are more likely to be deceived by manipulative behavior.     

The effect of sovereign wealth funds on corporations: Evidence of cash policies in Singapore

This paper studies the monitoring role of sovereign wealth funds (SWFs). By using unique dataset from one of the largest SWF: Temasek holdings, we find that SWF’s presence has a positive effect on cash holdings of portfolio companies. The effect is more pronounced for well-governed firms, indicating that Temasek increases corporate cash holdings through its active role in corporate governance. We further find supportive evidence that Temasek ownership affects cash holdings by hoarding excess cash and reducing capital expenditure, especially within firms with good governance. Temasek’s discerning effect on cash policies highlights the effective monitoring role of sovereign wealth funds.     

Evidence of herding and positive feedback trading for mutual funds in emerging Asian countries

When analysing the behavior of investors, the emphasis is usually on positive feedback and herding behavior, and the existing literature abounds with studies on the domestic strategy of mutual funds or on their impact. Due to the advantages in terms of the data, many studies investigate US data. However, with the increased flows of capital into emerging markets, studying the behavior of international mutual funds in emerging markets has become more and more important. Nevertheless, studies involving emerging markets are relatively rare. This study examines whether the positive feedback effect and herding behavior exist in Asian markets based on mutual fund data covering the period from 1996 to 2004. The long period enables us to test the sensitivities under the following four conditions, namely the capital volatility (volatile vs. stable), the degree of suffering during the Asian crisis (more suffering vs. less suffering), and the timing of the Asian crisis (pre-, during, and post-crisis), using the exchange rate regime. It was found in this study that mutual fund inflows into the Asian market were attracted by positive stock returns and currency appreciation. Furthermore, it was found that the positive feedback effect and herding behavior did exist in the Asian markets. However, the extent of the above behavior is not the same under different conditions.     

Risk Exposures and International Diversification: Evidence from iShares

Abstract:   We examine the newly developed international diversification instruments–iShares traded on the American Stock Exchange. Given the fact that iShares can be created and redeemed at will, the daily price of an iShare is expected to be equal to the daily portfolio value of the underlying assets in the home‐country market. Therefore, theoretically, iShare pricing should be influenced by the risk from the iShare's home‐country market and not the risk from the US market, per se . We evaluate the risk exposure of iShare prices to the US market (non‐fundamental effect) as well as the home‐country market (the fundamental effect). We find that most iShare returns are significantly influenced by and sensitive to the US market risk. Moreover, the US market appears to be the key permanent driving factor and the home‐country market is a pronounced transitory driving force for iShare prices. These findings indicate the presence of limits of international arbitrage for iShares. As a result, the international diversification benefits of iShares become questionable.     

Persistent performance in the mutual fund market: Tests with funds and investment advisers

Recent studies of mutual funds have concluded that there is some evidence of superior performance. We test for the existence of superior performance and its persistence with mutual funds and mutual fund investment advisers on a data set of monthly returns from 1979 to 1989 for 1,387 mutual funds grouped by 243 advisers. We find no evidence of superior performance or its persistence but we do find significant evidence of persistence of inferior performance. Consistent with previous studies our findings depend on the benchmark chosen, with multiple benchmarks producing a larger degree of inferior performance.
