Mutual Funds and Stock and Bond Market Stability

The unprecedented growth of mutual funds has raised questions about the impact of mutual fund flows on stock and bond prices. Many believe that the equity bull market of the 1990s is attributable to the huge flows of funds into equity mutual funds during this period and that a withdrawal of those funds could send stock prices plummeting. This article investigates the relationship between aggregate monthly mutual fund flows (sales, redemptions, and net sales) and stock and bond monthly returns during a 30-year period beginning January 1961 utilizing Granger causality and instrumental variables analysis. With one exception, flows into stock and bond funds have not affected either stock and bond returns. The exception is 1971–1981, when widespread redemptions from equity mutual funds significantly depressed stock returns. In contrast, the magnitude of flows into both stock and bond funds are affected significantly by stock and bond returns.     

The dynamics between stock returns and mutual fund flows: empirical evidence from the Greek market

This paper examines the interaction between mutual fund flows and stock returns in Greece. Specifically, we investigate the possibility of a causality mechanism through which mutual funds flows may affect stock returns and vice versa. The statistical evidence derived from the error correction model indicates that there is a bidirectional causality between mutual fund flows and stock returns. Cointegration results show that mutual funds flows cause stock returns to rise or fall. This may be explained by the fact that, in Greece, equity mutual funds are obliged by law to invest a certain percentage of their cash in stocks. Thus, inflows and outflows of cash in equity funds seem to cause higher and lower stock returns in Greek stock market.     

Investment behavior of mutual fund shareholders: The evidence from aggregate fund flows

The relationship of stock market returns with components of aggregate equity mutual fund flows (new sales, redemptions, exchanges-in, and exchanges-out) is examined. Vector autoregressions and tests of linear feedback show that the flow-return relationship exists solely between returns and exchanges-in and -out. Further, only exchanges-out are responsible for the contrarian flow behavior noted by Warther (1995). The evidence suggests that the various components reflect different investor objectives and information.     

Mutual fund flows,expected returns,and the real economy

This paper investigates the relation between mutual fund flows and the real economy. The findings of this paper support the theory that the positive co-movement of flows into equity funds and stock market returns is explained by a common response to macroeconomic news. Variables that predict the real economy as well as the equity premium – in particular dividend-price ratio, default spread, relative T-Bill rate and consumption-wealth ratio – are related to fund flows and can account for the correlation of flows and market returns. Furthermore, consistent with the information-response hypothesis, mutual fund flows are forward-looking and predict real economic activity.     

Investor Sentiment and Stock Returns: Evidence from Turkey

This paper investigates the relation between investor sentiment and stock returns on the Istanbul Stock Exchange, employing vector autoregressive (VAR) analysis and Granger causality tests. The sample period extends from July 1997 to June 2005. In the VAR models, stock portfolio returns and investor sentiment proxies are used as endogenous variables. Two dummy variables accounting for natural and economic crises are used as exogenous variables. The analysis results suggest that, excepting shares of equity issues in aggregate issues, stock portfolio returns seem to affect all investor sentiment proxies, namely closed-end fund discount, mutual fund flows, odd-lot sales-to-purchases ratio, and repo holdings of mutual funds. Investor sentiment does not appear to forecast future stock returns; only the turnover ratio of the stock market seems to have forecasting potential.     

High-frequency information content in end-user foreign exchange order flows

This article considers the impact of foreign exchange (FX) order flows on contemporaneous and future stock market returns using a new database of customer order flows in the euro-dollar exchange rate market as seen by a leading European bank. We do not find clear contemporaneous relationships between FX order flows and stock market changes at high frequencies, but FX flows do appear to have significant power to forecast stock index returns over 1–30 min horizons, after controlling for lagged exchange rate and stock market returns. The effects of order flows from financial customers on future stock market changes are negative, while the effects of corporate orders are positive. The latter results are consistent with the premise that corporate order flows contain dispersed, passively acquired information about fundamentals. Thus, purchases of the dollar by corporate customers represent good news about the state of the US economy. Importantly, though, there also appears to be extra information in corporate flows which is directly relevant to equity prices over and above the impact derived from stock prices reacting to (predicted) exchange rate changes. Our findings suggest that financial customer flows only affect stock prices through their impact on the value of the dollar.     

Pricing credit default swaps with bilateral value adjustments

The aim of this work is to examine the influence of mutual fund flows on market timing models, thus providing unbiased timing coefficients. However, as this control is motivated by the existing relationship between mutual fund flows and market returns, we first analyse this relationship, considering previous and concurrent market returns. However, unlike existing studies, we do not consider future returns, since investors do not observe them when making investment decisions. Thus, we feel it is more appropriate to consider expected market returns. We construct the expected market returns by running an AR model and considering the available public information about the macro-economy. The relationship is analysed under different conditions, considering a variety of different mutual fund flow measures, and considering (or not) the sensitivity of mutual fund flows to positive and negative market returns. We also propose different controls for the traditional timing models, and we further analyse the reverse-causality problem. The study demonstrates, for a sample of equity mutual funds registered for sale in the USA, that the poor market timing performance found in this and other prior studies can be completely attributed to the perverse effect of the fund managers’ liquidity service.     

The Information Content of Insider Call Options Trading

We examine the information content of two forms of insider trading, insider buy-, and sell-call transactions. We find that the information carried by stand-alone call purchases has only a short-term impact on stock prices, but over a longer term, call purchases accompanied by stock purchases have a positive impact. Call purchases accompanied by stock sales signal negative information about the firm, suggesting that some insiders use complicated trading strategies to manipulate the market. Insider sell-call transactions are followed by negative returns, indicating these transactions are driven by negative information about the firm.     

The impact of the Arab Spring and the Ebola outbreak on African equity mutual fund investor decisions

Financial development and stock markets have been widely considered to be key factors in economic growth. Among institutional investors, mutual funds play a key role in providing financial resources to stock markets, particularly in developing countries. Different from other investments, mutual fund flows could be affected by retail investors’ behavior and their overreaction to specific events. We considered 78 equity mutual funds that are geographically specialized in African countries and observed monthly flows and performance for the period of 2006–2015. We find that two major events, Ebola and the Arab Spring, significantly affected the fund flows, controlling for fund performance, expenses and market returns. Retail investors over-reacted to these major events, withdrawing their savings from the African mutual funds. This result is particularly strong when connected to the media coverage of these events: the higher the number of articles about Arab Spring and Ebola, the higher the withdrawals. These irrational investors’ behavior damaged the funds’ managers market timing ability, and reduced the equity capital injection into African stock markets. Our results have several implications for both holders of frontier market mutual funds and the overall asset management industry.     

Investor flows and stock market returns

This study simultaneously analyzes the relation between aggregate stock market returns and cash flows (net purchases of equity) from a broad array of investor groups in the United States over a long period of time from 1952 to 2004. We find strong evidence that quarterly flows are autocorrelated for each of the different investor groups. We further document a significant and positive contemporaneous relation between stock market returns and flows of Mutual Funds and Foreign Investors.     

Optimal Number of Stock Holdings in Mutual Fund Portfolios Based on Market Performance

Among the decisions that most mutual fund portfolio managers make is the number of stocks to hold. We posit that there is an optimal number of stocks for each mutual fund, reflecting the trade‐off between diversification benefits versus transactions and monitoring costs. We find a significant quadratic relation between number of stock holdings and risk‐adjusted returns for U.S. equity mutual fund portfolios during 1992–2000. Moreover, we find that changes in the number of stocks held over time are more highly correlated with mutual fund flows than with funds' investment returns.     

Asymmetric dynamic relations between stock prices and mutual fund units in Japan. An application of hidden cointegration technique

This paper examines “causality” effects between mutual fund flows and stock index prices in Japan. In particular, both the short and long run dynamics between stock prices and fund units are investigated. The novelty of our paper is the use of the hidden cointegration technique which attempts to capture heterogeneous fund flow reactions when stock index prices move up or down. Moreover, we employ the crouching error correction model (CECM) to assess the relationship between stock market movements and fund flow changes. The results show that stock prices and mutual fund units are cointegrated. In the case of positive movements there is a bi-directional effect interconnecting them, whereas for negative movements, causality runs only from fund flows to stock prices. The dynamics structure provides evidence that market microstructure, taxation and investors' sentiment affect stock price and unit formation.     

What moves international stock and bond markets?

We study the relation between international mutual fund flows and the different return components of aggregate equity and bond markets. First, we decompose international equity and bond market returns into changes in expectations of future real cash payments, interest rates, exchange rates, and discount rates. News about future cash flows, rather than discount rates, is the main driver of international stock returns. This evidence is in contrast with the typical results reported only for the US. Inflation news instead is the main driver of international bond returns. Next, we turn to the interaction between these return components and international portfolio flows. We find evidence consistent with price pressure, short-term trend chasing, and short-run overreaction in the equity market. We also find that international bond flows to emerging markets are more sensitive to interest rate shocks than equity flows.

Mutual Fund Trading Pressure: Firm‐Level Stock Price Impact and Timing of SEOs

We use price pressure resulting from purchases by mutual funds with large capital inflows to identify overvalued equity. This is a relatively exogenous overvaluation indicator as it is associated with who is buying—buyers with excess liquidity—rather than what is being purchased. We document substantial stock price impact associated with purchases by high‐inflow mutual funds, and find the probability of a seasoned equity offering (SEO), insider sales, and the probability of a stock‐based acquisition increase significantly in the four quarters following the mutual fund buying pressure. These results provide new evidence that firm managers are able to identify and exploit overvalued equity.     

Insider Trading Activity,Different Market Regimens,and Abnormal Returns

This paper show that corporate insiders earn abnormal returns by adjusting their own firm's stock trading to future market movements. Insider trading activity in bear markets is characterized by decreases in insider sales and increases in purchases, consistent with the view that those markets are followed by improved economic conditions. Conversely, insider sales increase and purchases decrease in bull markets, consistent with the view that inferior market conditions tend to follow those periods.     

Running From a Bear: How Poor Stock Market Performance Affects the Determinants of Mutual Fund Flows

Abstract:  Using a proprietary data set to study how past performance affects the determinants of mutual fund flows for a sample of load fund investors, I provide evidence that the determinants of fund flow depend on market conditions for both redemptions and purchases. Specifically, I show that, for redemptions, relative performance and risk adjusted performance are important determinants during a period of record flows into mutual funds. Conversely, during a period of poor performance, absolute performance becomes much more important and relative performance and risk adjusted performance become less important. For purchases, absolute performance, risk adjusted performance, and most relative performance measures become more important during the bear market.     

The relation between trades of domestic and foreign investors and stock returns in Sri Lanka

This study investigates the relation between equity flows and returns in Sri Lanka using daily trade data categorized by investor classes. The results show that purchases and sales of domestic and foreign investors, both institutional and individual, are positively related with past returns, except during crisis periods, when they are negatively related. Domestic institutional and foreign individual purchases lead to higher future returns whereas domestic individual purchases lead to lower future returns. Foreign institutional purchases do not impact future returns. Sales by domestic investors have no impact on future returns while sales by foreign investors lead to higher future returns.     

International Real Estate Mutual Fund Performance: Diversification or Costly Information?

We investigate the net effect between diversification benefit and information cost of international real estate mutual funds from three dimensions: whether investors can benefit from investing in international real estate mutual funds, whether managers of international real estate mutual funds possess superior market knowledge and timing abilities, and whether investors are motivated by returns or diversification. Our findings are threefold. First, the results show that international real estate mutual funds perform better and are less risky than domestic real estate mutual funds before Jun 2007. That is, diversification benefits outweigh the information costs, and investors therefore gain from investing in international real estate mutual funds. However, the benefit is reduced because of the economic shock of sub-prime financial crisis. Second, on average, neither international mutual fund managers nor domestic mutual fund managers possess market timing abilities. Finally, we find that fund flows are driven by investors’ return-chasing behaviors and fund size, but not by diversification purpose.     

Dedicated REIT Mutual Fund Flows and REIT Performance

This study examines the effects of weekly and monthly capital flows into the dedicated REIT mutual fund sector on aggregate REIT returns and, simultaneously, the effects of industry-level REIT returns on subsequent REIT mutual fund flows. The dynamic relation between REIT capital flows and returns is estimated using vector autoregression (VAR) techniques. Unlike static regression techniques, our dynamic model produces estimates of the short-run relationships, long-run relationships, impulse response functions, and forecast variance decompositions. We find evidence that REIT mutual fund flows are positively and significantly related to prior returns, while prior REIT mutual fund flows do not significantly influence REIT returns. However, contemporaneous flows do appear to have an initial positive effect, which is partially reversed one period later. The positive contemporaneous effect, however, is the result of unexpected REIT mutual fund flows, while the expected portion is insignificant.
