Momentum Strategies: Evidence from Pacific Basin Stock Markets

We investigate the profitability of momentum investment strategy in six Asian stock markets. Unrestricted momentum investment strategies do not yield significant momentum profits. Although we find that a diversified country‐neutral strategy generates small but statistically significant returns during 1981–1994, when we control for size and turnover effects we find that the country‐neutral profits dissipate. Our evidence suggests that the factors that contribute to the momentum phenomenon in the United States are not prevalent in the Asian markets.     

Trend‐Following Trading Strategies in U.S. Stocks: A Revisit

We show that previous findings regarding the profitability of trend‐following trading rules over intermediate horizons in futures markets also extend to individual U.S. stocks. Portfolios formed using technical indicators such as moving average or channel ratios, without employing cross‐sectional rankings of any kind, tend to perform about as well as the more commonly examined momentum strategies. The profitability of these strategies appears significant, both statistically and economically, through 2007, but evidence of profitability vanishes after 2007. Market‐state dependence, while clearly present, does not explain the post‐2007 reduction in returns to these strategies.     

Reconcilable Differences: Momentum Trading by Institutions

A growing literature evaluates the relation between lag returns and demand by institutional investors. Given that lag returns and institutional ownership are directly observable, it is surprising that previous tests yield dramatically different conclusions. This study examines differences across studies and finds that four factors account for these discrepancies: (1) value‐weighting versus equal‐weighting across stocks, (2) averaging versus aggregating over managers, (3) disagreement in the signs of measures of institutional demand, and (4) correlation between current capitalization and both lag returns and measures of institutional demand. Controlling for these factors, the results across different methods are remarkably uniform.     

Post‐Retirement Financial Strategies: Forecasts and Valuation

This paper uses a discrete‐time, discrete‐state Monte Carlo simulation model to evaluate representative strategies for investing and spending a fixed sum designed to fund consumption during the period after retirement. Two assets are considered – one providing a riskless real return, the other a market portfolio of bonds and stocks. A stochastic process for the returns from the market portfolio is proposed. Then a set of Arrow‐Debreu state prices is obtained on the assumption that the market portfolio is an efficient investment strategy. The model is used to forecast ranges of consumption and ranges of the ratios of year‐to‐year consumption, and also to estimate the values of components of future consumption.     

The Sophisticated and the Simple: the Profitability of Contrarian Strategies

A variety of variables have been used to form contrarian portfolios, ranging from relatively simple measures, like book‐to‐market, cash flow‐to‐price, earnings‐to‐price and past returns, to more sophisticated measures based on the Ohlson model and residual income model (RIM). This paper investigates whether: (i) contrarian strategies based on RIM perform better or worse than those based on the Ohlson model; (ii) contrarian strategies based on more sophisticated valuation models (e.g. Ohlson and RIM) perform much better than the relatively simpler ranking variables that have been used so extensively in the finance literature. Given that the RIM and Ohlson models require greater information inputs and technical know‐how, and make different implicit assumptions on future abnormal earnings, it is important to ascertain if they offer significantly greater contrarian profits to outweigh the increased costs that they entail. Indeed, our surprising finding is that simple cash flow‐to‐price measures appear to do almost as well as the more sophisticated alternatives. One would have expected the sophisticated models to significantly outperform the simple cash flow to price model for the reasons given by Penman (2007) .     

Heterogeneous Background Risks and Portfolio Choice: Evidence from Micro‐level Data

We construct a set of household‐level background risk variables to capture the covariance structure of three nonfinancial assets and two financial assets. These risks are in general statistically significant and economically important for a household's stock market participation and stockholdings. A one‐standard‐deviation increase in background risks reduces the participation probability by 11% and the stockholdings‐to‐wealth ratio by 4%. The volatilities of labor income, housing value, and business income reduce a household's participation and stockholdings. A household with labor income highly correlated with stock (bond) returns is less (more) likely to invest in stock.     

Post‐Earnings Announcement Drift: Bounds on Profitability for the Marginal Investor

The persistence of the post‐earnings announcement drift (PEAD) leads many to believe that trading barriers prevent investors from eliminating it. We examine two factors that have not been adequately addressed by the literature: the exact timing of earnings announcements and liquidity costs. Under a wide range of timing and cost assumptions, our results leave little doubt that over our sample period the PEAD was highly profitable after trading costs. An additional incremental investor could have earned hedged‐portfolio returns of at least 14% per year after trading costs. Over our sample period, investors did indeed leave money on the table.     

Does the Momentum Strategy Work Universally? Evidence from the Japanese Stock Market

This paper investigates effectiveness of momentum strategies in the Japanese stock market during the period of 1975 to 1997. The main findings of this research are that momentum strategy portfolios which invest in past three-to-twelve month winners and sell past three-to-twelve month losers lose about 0.5% per month over the subsequent three to twelve months. This means that stock prices in the Japanese stock market reverse rather than continue over a medium-term horizon. The most significant reversal pattern is observed at the first month of portfolio formation and is unique to small stocks. Even with the market risk and size factor controlled, the price reversal is still present.     

The U.S. Share of Trading Volume in Cross‐Listings: Evidence from Canadian Stocks

I analyze the firm‐specific determinants of the U.S. share of trading volume for 126 U.S.‐listed Canadian firms. I find that the U.S. share of volume is directly related to the mass of informed and liquidity traders in the United States relative to Canada, as proxied by relative analyst following, relative duration of listing, and the U.S. share of sales. Evidence also supports the market liquidity argument that the market with lower spreads and greater depths has greater volume. Finally, the U.S. share is directly related to the relative sensitivity of the stock's value to information in the United States.     

Stock‐Split Post‐Announcement Returns: Underreaction or Market Friction?

We explore the relationship between stock splits and subsequent long‐term returns during the period from 1950 to 2000. We find that, contrary to much previous research, firms do not exhibit positive long‐term post‐split returns. Instead, we find that significant positive returns after the announcement date do not persist after the actual date of the stock split. We also observe that abnormal returns are correlated with the price‐delay or market friction. We conclude that the stock‐split post‐announcement “drift” is only of short duration, and it is attributable to trading frictions rather than behavioral biases.     

The week-of-the-year effect: Evidence from around the globe

This study investigates another calendar anomaly the literature does not yet address – the week-of-the-year (WOY) effect. Using the weekly returns on the stock market indexes of 20 countries worldwide, for a period that ends in December 2010, the findings demonstrate that returns in Week 44, which starts on October 29 and ends on November 4, are positive in 19 of the 20 countries, and in 18 of them, it is also statistically significant. In contrast, the returns for Week 43, which starts on October 22 and ends on October 28, are negative in 19 of the 20 countries, and statistically significant for most of the countries. We also apply an investment strategy derived from these findings to a prediction period (2009–2010), and find that this strategy beats the simple buy-and-hold policy by a substantial margin.     

Emerging from Bankruptcy with When‐Issued Trading

We examine the set of firms that emerged from Chapter 11 bankruptcy and traded on a when‐issued basis before their official return to the regular way in NASDAQ, Amex, or NYSE. We find that this when‐issued market is liquid and price efficient. The when‐issued closing price is a good indicator of the first closing price in the regular way market. Emerging firms that have when‐issued trading experience lower regular way volatility and smaller relative spreads than those without when‐issued trading. Our probit regressions show that firm size is an important determinant of the adoption of when‐issued trading.     

The Value of Adjusting the Bias in Recommendations: International Evidence

The financial literature has shown that both earnings forecasts and investment recommendations are optimistically biased. However, while the bias in earnings forecasts has decreased over time and even some recent studies show that they are no longer optimistic, in the case of investment recommendations this bias still remains relatively constant over time. Therefore, it seems that recommendations are less credible to investors than earnings forecasts. The vast majority of recommendation studies have been carried out at the country level. In this paper, we use an international context to study whether profitable investment strategies exist when adjusting the recommendation bias of each analysed country. The adjustment we propose to correct this bias takes into account the differences across countries, and also varies in time to correct for the changes in bias over time within countries. Our empirical results show that there are in fact significant differences in the level of bias among countries, with the US and the UK being the countries with the highest bias. Second, the adjusted consensus portfolios are more orthogonal to typical investment styles (size, book‐to‐market and attention) and we find that investors could implement a higher number of profitable investment strategies using this adjusted measure. In this line, the results show that the countries with the lowest bias obtain the highest risk adjusted abnormal returns. Third, our work entails a practical implication, as it shows the value embedded in a simple necessary adjustment in the global asset management context. This is an important result showing that profitable investment strategies exist when considering a global portfolio based on adjusted recommendations.     

The S&P500 index effect reconsidered: Evidence from overnight and intraday stock price performance and volume

This study focuses on S&P500 inclusions and deletions, examining the impact of potential overnight price adjustment after the announcement of an S&P500 index change. We find evidence of a significant overnight price change that diminishes the returns available to speculators although there are still profits available from the first day after announcement until a few days after the actual event. More importantly, observing the tick-by-tick stock price performance and volume effects on the key days during the event window for the first time, we find evidence of consistent trading patterns during trading hours. A separate analysis of NASDAQ and NYSE listed stocks allows for a detailed examination of the price and volume effect at an intra-day level. We find that index funds appear to cluster their rebalancing activities near to and after the close on the event date, suggesting that they are more concerned with tracking error than profit.     

The First‐ and Second‐Hand Effect of Analysts' Stock Recommendations: Evidence from the Swiss Stock Market

This paper empirically investigates the impact of both the first release of analysts' stock recommendations to a limited clientele and the subsequent dissemination of the same information in a major newspaper to a broader audience. For a sample of 1460 stock recommendations published in FuW, Switzerland's major financial newspaper, significant positive abnormal returns on the day of the original release of buy recommendations and on the day of publication in FuW are documented. Tests of the price pressure and information hypotheses reveal that analysts' recommendations contain new information, which is quickly incorporated in the stock prices on the first release of this information. In contrast, the statistically significant announcement effects associated with the subsequent publication can be primarily ascribed to price pressure in the underlying securities.     

Profitability of momentum strategies in international markets: The role of business cycle variables and behavioural biases

The paper investigates whether business cycle variables and behavioural biases can explain the profitability of momentum trading in three major European markets. Unlike previous studies, the paper nests both risk-based and behavioural-based variables in a two-stage model specification in an attempt to explain momentum profits. The findings show that, although momentum profitability in European markets is unexplained by conditional asset pricing models, it is attributable to asset mispricing that systematically varies with global business conditions. In addition, behavioural variables do not appear to matter much. Thus risk factors, which are undetected thus far and are largely attributable to the business cycle, could explain the momentum payoffs in European stock markets.     

Yes,The Value Line Enigma Is Still Alive: Evidence from Online Timeliness Rank Changes

Beginning June 9, 2005, Value Line started announcing its Timeliness changes online at 10:00 a.m. on Thursday, one day earlier than Friday noon's post‐delivery. We confirm that the Value Line effect still exists but shifts to Thursday in the Internet era. Unlike previous findings, the next‐day abnormal return after the announcement has disappeared, suggesting that the market efficiently priced the change. We find that a portfolio upgraded from rank 5 to 4 gains the highest cumulative abnormal return of 9.07% over a 50‐day window. Finally, we find that the post‐earnings announcement drift does not explain the Value Line enigma.     

Risk‐Adjusted Long‐Term Contrarian Profits: Evidence from Non‐S&P 500 High‐Volume Stocks

Can trading volume help unravel the long‐term overreaction puzzle? With portfolios of non‐S&P 500 NYSE stocks, we show that (1) both the high‐ and low‐volume (abnormal volume) contrarian portfolios earn a much higher market‐adjusted excess return than the normal‐volume contrarian portfolio, (2) however, when leverage‐induced risk is factored in, excess returns from contrarian portfolios with normal‐ and low‐volume stocks are insignificant, (3) only excess returns from high‐volume contrarian stocks are significant and cannot be explained by the time‐varying risk and return framework, and (4) such high‐volume, risk‐adjusted excess returns arise mainly from winner (glamour) stocks.
