我国社保基金持股偏好研究

社保基金在证券市场上的投资表现会直接影响其运行的稳定性,由于其资金来源的特殊性,社保基金对于选择投资对象有没有明显的偏好呢？本文利用2008—2018年我国A股上市公司的数据,研究社保基金的持股偏好。研究表明,社保基金在进行投资时对于经营业绩好、风险性低、股权集中度高、估值偏低的股票具有明显的偏好。进一步研究发现,与保险公司偏好股权集中度低的股票、公募基金偏好流动性高的股票相比,社保基金更偏好股权集中度高的股票,而对于流动性高的股票并没有明显的偏好。     

Explaining persistence in mutual fund performance

This study investigates the determinants of persistence in mutual fund performance. Previous research that uses factor-mimicking portfolios and characteristic benchmarks to model fund performance fails to explain all the persistence in fund returns. This study employs a model that directly relates mutual fund returns to the characteristics of the stocks held by funds. Adjusting fund returns for the size of the stocks in which funds invest and financial ratios intended to capture fund manager investment styles explains all the persistence in mutual fund returns from 1976–1985, the period in which persistence is most prevalent.     

Short term persistence in mutual fund market timing and stock selection abilities

Using daily return data from 448 actively managed mutual funds over a recent 9-year period, we look for persistence, over two consecutive quarters, in the ability of funds to select individual stocks and time the market. That is, we decompose overall fund performance into excess returns resulting from stock selection and timing abilities and we separately test for persistence in each ability. We find persistence in the ability to time the market only among well performing funds and in the ability to select stocks only among the very best and worst performers. The existing literature patterns appear only when funds are ranked by their overall performance, which includes stock selection, market timing and fees. With respect to overall performance, there is persistence among most poorly performing and only the top well performing funds. Furthermore, the profitability of a winner-picking strategy depends on the rebalancing frequency and potentially the size of the investment. Small investors cannot profit, whereas large investors can take advantage of the class-A share fee structure and realize positive abnormal returns by annually rebalancing their portfolios.     

The Italian hedge funds industry: An empirical analysis of performance and persistence

This study analyses Italian hedge funds performance and persistence. The peculiarity of the Italian hedge fund industry is that 95% of the hedge funds are funds of hedge funds (FoHF), whereas only 5% of them employ other investment styles. Using monthly data on FoHF provided by MondoHedge, we examine the impact of both market variables and funds’ own characteristics on funds performance using panel data. We find that the European, the Japanese and the emerging markets equity markets, and the commodity market have a positive impact on Italian FoHF performances, while the US Bond Market negatively affects them. Moreover, we find performance fees and notice days to have a negative impact on funds performances. Finally, we test the presence of performance persistence. Employing two different nonparametric methods, we find that funds performances are persistent on a monthly and quarterly basis, while the regression-based parametric method provides evidence of persistence only on a monthly basis.     

Portfolio concentration and fund manager performance

This research examines the relationships among portfolio concentration, fund manager skills, and fund performance in Taiwan's equity mutual fund industry, yielding several empirical findings as follows. First, after controlling for other factors, concentrated equity funds tend to have smaller net asset values, larger fund flows, higher turnover rates, and a younger age and prevail in smaller fund families. Second, concentrated fund managers buy and sell stocks more smartly based on economic trends or market factors than do diversified fund managers, i.e., they have better market‐timing abilities. Third, only partial evidence supports the premise that concentrated equity funds have better next‐quarter risk‐adjusted performances than do diversified ones, as these fund managers' skills positively correlate to risk‐adjusted fund performance. Fourth, fund managers who have better stock‐picking abilities and intensively invest in certain industries generally exhibit better Carhart's alpha in the next quarter than do other fund managers. Fifth, fund managers' stock‐picking abilities more closely relate to long‐term performance than do their market‐timing abilities. Lastly, positive performance persistence is much stronger than negative performance persistence, but concentrated funds do not have stronger performance persistence than do diversified funds.     

False Discoveries in UK Mutual Fund Performance

We use a multiple hypothesis testing framework to estimate the false discovery rate (FDR) amongst UK equity mutual funds. Using all funds, we find a relatively high FDR for the best funds of 32.8% (at a 5% significance level), which implies that only around 3.7% of all funds truly outperform their benchmarks. For the worst funds the FDR is relatively small at 7.6% which results in 22% of funds which truly underperform their benchmarks. For different investment styles, this pattern of very few genuine winner funds is repeated for all companies, small companies and equity income funds. Forming portfolios of funds recursively for which the FDR is controlled at a ‘acceptable’ value, produces no performance persistence for positive alpha funds and weak evidence of persistence for negative alpha funds.     

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.     

Persistence and the four‐factor model in the Australian funds market: a note

We investigate whether Australian fund managers are able to deliver persistent performance using Carhart’s (1997) four‐factor model. Short‐ and long‐term persistence is examined and the sample is also divided into unit trusts and superannuation funds. We do not find evidence of persistence in any sample of funds. We find that winner (loser) funds tend to hold past winner (loser) stocks. Winner and loser unit trusts both appear to have positive exposure to small stocks.     

A return-based approach to identify home bias of European equity funds

This paper introduces a return-based approach to studying a possible home bias of European equity funds by estimating their exposures to their domestic markets. We first confirm the robustness of our approach using simulated portfolios with different proportions of domestic and foreign stocks. The empirical analysis examines equity funds domiciled in 15 European countries that invest in European stocks. We examine individual funds as well as portfolios comprising funds that are all domiciled in a particular country. Our findings reveal that the portfolios of four domiciles show a significant home bias. Moreover, we observe that in seven domiciles more than a quarter of the individual funds are home-biased. These results are robust when controlling for fund-specific benchmarks or for the average country exposures of all funds in our final sample. Finally, a home bias of individual funds is not related to superior performance, but actually results in higher investment risk consistent with underdiversification.     

International evidence on Islamic equity fund characteristics and performance persistence

This research examines the presence of performance persistence and the impact of fund-specific characteristics on Islamic equity fund (IEF) performance. We conduct an empirical study based on an extensive Database of 301 IEFs and for the period 1999–2013. Our results reveal that fund age, family size and management fees have a significant positive impact on IEF performance. On the other hand, other characteristics such as flows, minimum investment size, higher liquidity, and load fees have negative effect on fund performance, whereas fund size has no significant impact on IEF performance. Our study reveals that Islamic equity funds exhibit negative performance persistence. The paper provides relevant practical implications for managers, analysts and investors. To our knowledge, this empirical study is the first to investigate the intrinsic determinants of Islamic equity fund performance, with sufficient statistical power that is based on an effective sample size with international diversity.     

Retail Financial Innovation and Stock Market Dynamics: The Case of Target Date Funds

Target date funds (TDFs) are designed to provide unsophisticated or inattentive investors with age-appropriate exposures to different asset classes like stocks and bonds. The rise of TDFs has moved a significant share of retirement investors into macrocontrarian strategies that sell stocks after relatively good stock market performance. This rebalancing drives contrarian flows across equity mutual funds held by TDFs, stabilizing their funding, and reduces stock returns for stocks disproportionately held by these funds when stock market returns are relatively high. Continued growth in TDFs and similar investment products may dampen stock market volatility and increase the transmission of shocks across asset classes.     

The Performance of Local versus Foreign Mutual Fund Managers

In this paper we examine the performance of US equity funds (locals) versus UK equity funds (foreigners) also investing in the US equity market. Based on informational disadvantages one would expect the UK funds to under‐perform the US funds, especially in the research‐intensive small company market. After controlling for tax treatment, fund objectives, investment style and time‐variation in betas, we do not find evidence for this. In the small company segment we even find a slight out‐performance for UK funds compared to US funds. Finally we observe a home bias in the UK portfolios, which is partly attributable to UK funds investing in cross‐listed stocks in the USA.     

On Persistence in Mutual Fund Performance

Using a sample free of survivor bias, I demonstrate that common factors in stock returns and investment expenses almost completely explain persistence in equity mutual funds' mean and risk-adjusted returns. Hendricks, Patel and Zeckhauser's (1993) “hot hands” result is mostly driven by the one-year momentum effect of Jegadeesh and Titman (1993) , but individual funds do not earn higher returns from following the momentum strategy in stocks. The only significant persistence not explained is concentrated in strong underperformance by the worst-return mutual funds. The results do not support the existence of skilled or informed mutual fund portfolio managers.     

Characteristic Factors and Fund Evaluation in Korea

Factors that govern common variations in equity returns in Korea are identified and the authors examine whether they are priced. Size and the ratio of book value to price turn out to be the determinants of common variations, and these variations appear to be priced. The momentum factor shows mixed results depending on the samples, while macroeconomic factors consistently fail to group stocks in any meaningful manner. These factors are utilized to assess the performance of the retail equity funds. Characteristic-based performance analysis reveals that high risk-adjusted excess returns are accompanied by high selection and timing abilities of fund managers. Risk-adjusted returns are more persistent than unadjusted returns.     

The role of future economic conditions in the cross-section of stock returns: Evidence from the US and UK

Our study investigates the explanatory power of future economic conditions on individual stock returns in the US and UK equity markets. We analyse a new trading strategy that is based on rational forecasts of future real activity. In addition, we specifically examine the performance of this trading strategy applied to two different classifications of stocks – procyclical stocks and countercyclical stocks. Our findings indicate a strong persistence in the relationship between returns on pro-cyclical stocks and the business cycle. However, such persistence is not present when moving to counter-cyclical stocks in the US and the UK. From this we suggest that US and UK equity investors who predict future real activity accurately can improve their investment profitability by longing pro-cyclical stocks when they expect future economic conditions to be above the long-run trend and shorting those stocks when future activity is anticipated to be below the steady state.     

Do social factors influence investment behavior and performance? Evidence from mutual fund holdings

We study the economic significance of social dimensions in investment decisions by analyzing the holdings of U.S. equity mutual funds over the period 2004–2012. Using these holdings, we measure funds’ exposures to socially sensitive stocks in order to answer two questions. What explains cross-sectional variation in mutual funds’ exposure to controversial companies? Does exposure to controversial stocks drive fund returns? We find that exposures to socially sensitive stocks are weaker for funds that aim to attract socially conscious and institutional investor clientele, and they relate to local political and religious factors. The financial payoff associated with greater “sin” stock exposure is positive and statistically significant, but becomes non-significant with broader definitions of socially sensitive investments. Despite the positive relation between mutual fund return and sin stock exposure, the annualized risk-adjusted return spread between a portfolio of funds with highest sin stock exposure and its lowest-ranked counterpart is statistically not significant. The results suggest that fund managers do not tilt heavily towards controversial stocks because of social considerations and practical constraints.     

Management of flow risk in mutual funds

This paper is the first to relate the investment practices of U.S. equity mutual funds to their management of flow risk, defined as the adverse effect of investor in- and outflows on fund performance. Using a comprehensive merged sample of 2585 actively managed U.S. domestic equity funds from the CRSP mutual fund database and the SEC’s regulatory N-SAR filings, we are the first to detect differences in funds’ responses to flow risk. We find that funds using derivatives, such as options and futures on indices as well as individual stocks, have higher performance than non-using funds. We further show that this outperformance is the result of superior flow risk management using these derivatives and not a result of derivatives based stock-picking or market-timing activities. Overall, our findings document that superior flow management ability is valuable when managing open-end mutual funds and should be considered by investors and researches when evaluating fund performance.     

Performance of Enhanced Index and Quantitative Equity Funds

We examine the performance of enhanced index and quantitative equity funds. Both types of funds use quantitative models in investment selection. Enhanced index funds set an explicit objective to outperform a benchmark index. Proponents of quantitative funds argue that their management style takes human emotions out of the investment decision‐making process and leads to more objective stock selection. We find evidence of outperformance by quantitatively managed growth funds, especially those investing in small cap stocks.     

A new perspective on performance persistence: evidence using portfolio holdings

We investigate the existence and sources of performance persistence for Australian equity funds, using monthly portfolio holdings data. We find significant persistence among outperforming rather than underperforming funds, which is primarily related to security selection skill, and is associated with growth‐orientated funds. Meanwhile, the relation between persistence and momentum is secondary and nuanced. Further, persistence largely derives from existing holdings, while subsequent active trading contributes only moderately positive returns for both outperforming and underperforming funds. We also find that persistence fades beyond 6 months and vanishes after 24 months. Our findings differ from those for U.S. equity funds and previous Australian studies, implying that persistence may vary with market context and its identification may depend on data availability.     

Do Funds Make More When They Trade More?

We model fund turnover in the presence of time‐varying profit opportunities. Our model predicts a positive relation between an active fund's turnover and its subsequent benchmark‐adjusted return. We find such a relation for equity mutual funds. This time‐series relation between turnover and performance is stronger than the cross‐sectional relation, as the model predicts. Also as predicted, the turnover‐performance relation is stronger for funds trading less‐liquid stocks and funds likely to possess greater skill. Turnover is correlated across funds. The common component of turnover is positively correlated with proxies for stock mispricing. Turnover of similar funds helps predict a fund's performance.
