Abstract:  We apply a recent nonparametric methodology to test the market timing skills of UK equity and balanced mutual funds. The methodology has a number of advantages over the widely used regression based tests of Treynor-Mazuy (1966) and Henriksson-Merton (1981) . We find a relatively small number of funds (around 1%) demonstrate positive market timing ability at a 5% significance level while around 19% of funds exhibit negative timing and on average funds miss-time the market. However, controlling for publicly available information we find very little evidence of market timing ability based on private timing signals. In terms of investment styles, there are a small number of successful positive market timers amongst Equity Income and 'All Company' funds but not among either Small Stock funds or Balanced funds, although a few small stock funds are found to time a small stock index rather than a broad market index.  相似文献

This paper employs daily fund and index data, the classical Treynor and Mazuy timing model, and two multi-factor extensions to measure the market timing ability of global asset allocation funds. These funds differ from traditional global or international funds in that they face fewer investment constraints and are known to actively shift funds across a wide variety of asset classes. When using the classical Treynor and Mazuy timing models, I find evidence of poor market timing ability. However, this evidence disappears when timing ability is examined using two multi-factor models. The results from Treynor and Mazuy are spurious since both multi-factor extensions do a much better job in explaining the variation in average fund returns.  相似文献

We examine emerging market and global macro hedge funds and find a significant positive relation between hedge funds’ future returns and their exposure to both emerging market equities and emerging market currencies. We present evidence that the strong predictive power of emerging market betas is related to the superior market‐timing ability of these fund managers. Results are robust after controlling for commonly used hedge fund factors, the emerging market equity index, lagged fund returns, liquidity risk, and fund characteristics. Our results suggest that hedge funds can earn positive excess returns by timing their exposure to emerging market securities.  相似文献

The literature on gold is dominated by empirical studies on its diversification, hedging, and safe haven properties. In contrast, the question “When to invest in gold?” is generally not analyzed in much detail. We test more than 4000 seasonal, technical, and fundamental timing strategies for gold and find evidence for some market timing ability and economic gains relative to a passive buy-and-hold benchmark. However, since the results are not robust to data-snooping biases and limited to specific evaluation periods, we conclude that our findings support the efficiency of the gold market.  相似文献

自从市场时机资本结构理论提出以来,国内外学者从理论的解释能力和实用性等方面对这一新兴融资决策理论进行了大量研究,并得出许多有意义的结论。然而目前的实证检验主要基于市值账面比(M/B)指标作为市场时机代理变量,这一指标引起学者们很大争议,研究结论缺乏可靠性。本文根据我国资本市场实际特征选择股票换手率作为市场时机代理变量,实证检验了市场时机与外部融资方式选择的关系,同时引入股票收益变量检验市场时机对资本结构动态变动的综合影响。研究结论显示,换手率在企业权益融资中具有重要作用,换手率较高时企业选择发行更多的股权融资,股票换手率和股票收益均对资本结构变动具有显著的负向影响。这表明我国上市公司确实存在着融资选择的市场时机效应。  相似文献

Can Managers Forecast Aggregate Market Returns?   总被引:2,自引:0,他引:2  
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.  相似文献

In this paper, we examine the profitability of insider trading in firms whose securities trade in the OTC/NASDAQ market. Although the evidence suggests timing and forecasting ability on the part of insiders, high transaction costs (especially bid-ask spreads) appear to eliminate the potential for positive abnormal returns from active trading. By implication, outside investors who mimic the trading of insiders are also precluded from earning abnormal profits. In addition, we provide evidence on the determinants of insiders' profits. The data suggest that insiders closer to the firm trade on more valuable information than insiders removed from the firm.  相似文献

On the Timing and Execution of Open Market Repurchases   总被引:2,自引:0,他引:2  
Little is known about the timing and execution of open marketrepurchases. U.S. firms are under no obligation to disclosewhen they are trading, and generally report only quarterly changesin shares outstanding. We use 64 firms' supplementally disclosedrepurchase trading data to provide the first examination ofrepurchase timing and execution. Across the days reported inour sample, firms adopted a variety of execution styles rangingfrom immediate intense repurchasing to delayed and smoothedrepurchasing. We find no clear evidence that repurchases aretimed to coincide with, precede, or follow, days on which informationis released. We benchmark the costs and value of a given repurchaseprogram against naive accumulation strategies achieving thesame terminal portfolio. While there is considerable variationacross the firms, NYSE firms on average beat their benchmarks,whereas NASDAQ firms do not. Finally, we document the liquidityimpact of open market repurchases. We find that repurchasingcontributes to market liquidity by narrowing bid-ask spreadsand attenuating the price impact of order imbalances on dayswhen repurchase trades are completed.  相似文献

On the Timing Ability of Mutual Fund Managers   总被引:9,自引:0,他引:9  
Existing studies of mutual fund market timing analyze monthly returns and find little evidence of timing ability. We show that daily tests are more powerful and that mutual funds exhibit significant timing ability more often in daily tests than in monthly tests. We construct a set of synthetic fund returns in order to control for spurious results. The daily timing coefficients of the majority of funds are significantly different from their synthetic counterparts. These results suggest that mutual funds may possess more timing ability than previously documented.  相似文献

This study examines the performance of Irish domiciled funds over the period 1988 to 2000. The study specifically examines whether Irish portfolio managers, particularly in light of the small and thinly traded domestic market, can effectively partake in micro or macro forecasting. Four alternative models are used to jointly assess micro and macro forecasting, while a fifth non-parametric model is used to solely examine market timing effects. The results reveal consistent evidence of poor micro forecasting/stock selection ability across the funds examined. The macro forecasting results are more varied, with some evidence of positive timing ability in two of the models. In addition, significant correlations are generally found between the funds micro and macro forecasting ability, while diagnostic tests reveal limited evidence of mis-specification in the models used.  相似文献

We study market timing and pecking order in a sample of debt and equity issues and share repurchases of Canadian firms from 1998 to 2007. We find that only when firms are not financially constrained is there evidence that firms issue (repurchase) equity when their shares are overvalued (undervalued) and evidence that overvalued issuers earn lower postannouncement long‐run returns. Similarly, we find that only when firms are not overvalued do they prefer debt to equity financing. These findings highlight an interaction between market timing and pecking order effects.  相似文献

Market discipline is an article of faith among financial economists, and the use of marketdiscipline as a regulatory tool is gaining credibility. Effective market discipline involvestwo distinct components: security holders' ability to accurately assess the condition of afirm (monitoring) and their ability to cause subsequent managerial actions to reflect thoseassessments (influence). Substantial evidence supports the existence of market monitoring.However, the existing evidence about market influence involves relatively rare events suchas management turnover. This paper seeks evidence that U.S. bank holding companies'security price changes reliably influence subsequent managerial actions. Although weidentify some patterns consistent with beneficial market influences, our methodology doesnot provide strong evidence that stock or (especially) bond investors regularly influencemanagerial actions. Day-to-day market influence remains, for the moment, more a matterof faith than of empirical evidence.  相似文献

Using demand shifts induced by demographics, we evaluate capital budgeting and market timing. Capital budgeting implies that industries anticipating positive demand shifts in the near future should issue more equity to finance greater capacity. To the extent that demand shifts in the distant future are not incorporated into equity prices, market timing implies that industries anticipating positive shifts in the distant future should issue less equity due to undervaluation. The evidence supports both theories: new listings and equity issuance respond positively to demand shifts during the next 5 years and negatively to demand shifts further in the future.  相似文献

We propose a new definition of skill as general cognitive ability to pick stocks or time the market. We find evidence for stock picking in booms and market timing in recessions. Moreover, the same fund managers that pick stocks well in expansions also time the market well in recessions. These fund managers significantly outperform other funds and passive benchmarks. Our results suggest a new measure of managerial ability that weighs a fund's market timing more in recessions and stock picking more in booms. The measure displays more persistence than either market timing or stock picking alone and predicts fund performance.  相似文献

We use statistical model selection criteria and Avramov's (2002) Bayesian model averaging approach to analyze the sample evidence of stock market predictability in the presence of model uncertainty. The empirical analysis for the Swiss stock market is based on a number of predictive variables found important in previous studies of return predictability. We find that it is difficult to discard any predictive variable as completely worthless, but that the posterior probabilities of the individual forecasting models as well as the cumulative posterior probabilities of the predictive variables are time-varying. Moreover, the estimates of the posterior probabilities are not robust to whether the predictive variables are stochastically detrended or not. The decomposition of the variance of predicted future returns into the components parameter uncertainty, model uncertainty, and the uncertainty attributed to forecast errors indicates that the respective contributions strongly depend on the time period under consideration and the initial values of the predictive variables. In contrast to AVRAMOV (2002), model uncertainty is generally not more important than parameter uncertainty. Finally, we demonstrate the implications of model uncertainty for market timing strategies. In general, our results do not indicate any reliable out-of-sample return predictability. Among the predictive variables, the dividend-price ratio exhibits the worst external validation on average. Again in contrast to AVRAMOV (2002), our analysis suggests that the out-of-sample performance of the Bayesian model averaging approach is not superior to the statistical model selection criteria. Consequently, model averaging does not seem to help improve the performance of the resulting short-term market timing strategies.  相似文献

This study uses a methodology that is independent of beta estimates to provide empirical evidence on the success of market timing by mutual fund managers. A fund's success at market timing is evaluated by determining if the percentage of the portfolio invested in stocks increases prior to an upturn in the general level of stock market prices and declines prior to a downturn in the level of stock prices. No evidence is found that managers possess, as a group, any market timing ability.  相似文献

This paper examines the role of capital market conditions and target leverage on the marginal financing decisions of Real Estate Investment Trusts (REITs), which include both capital raising and capital reduction activities. We investigate the relevance of a hybrid hypothesis whereby REITs have target leverage, but they also choose and time their marginal financing decisions according to the capital market conditions. The empirical results suggest that target leverage behavior plays a secondary role to market timing behavior in the financing decisions of REITs. In particular, we find strong and consistent evidence that REITs exhibit market timing behavior in terms of when and what type of capital to issue or reduce. Such market timing practices, motivated by attempts to take advantage of capital market conditions, may shift the firms away from their target leverage. However, we observe that in the long run, most REITs do move their capital structure towards the target debt level.  相似文献
