Stock returns, order imbalances, and commonality: Evidence on individual, institutional, and proprietary investors in China

Warren Bailey; Jun Cai; Yan-Leung Cheung; Fenghua Wang
Journal of Banking & Finance 2009 33(1), 9-19
Using a unique dataset from the Shanghai Stock Exchange, we study the relation between daily open-to-close stock returns and order imbalances, and the commonality in order imbalances across individual, institutional, and proprietary investors. We find that institutional (proprietary) order imbalances have a larger price impact, but account for a significantly smaller proportion of daily price fluctuations. Commonality is much stronger for individual, rather than institutional (proprietary), order imbalances. Institutional (proprietary) investors favor large capitalization stocks, and co-movement in institutional (proprietary) order imbalances is stronger for these stocks.

Social Comparisons and Contributions to Online Communities: A Field Experiment on MovieLens

American Economic Review 2010 100(4), 1358-1398
We design a field experiment to explore the use of social comparison to increase contributions to an online community. We find that, after receiving behavioral information about the median user's total number of movie ratings, users below the median demonstrate a 530 percent increase in the number of monthly movie ratings, while those above the median decrease their ratings by 62 percent. When given outcome information about the average user's net benefit score, above-average users mainly engage in activities that help others. Our findings suggest that effective personalized social information can increase the level of public goods provision.

Sensation Seeking and Hedge Funds

Journal of Finance 2018 73(6), 2871-2914 open access
We show that, motivated by sensation seeking, hedge fund managers who own powerful sports cars take on more investment risk but do not deliver higher returns, resulting in lower Sharpe ratios, information ratios, and alphas. Moreover, sensation‐seeking managers trade more frequently, actively, and unconventionally, and prefer lottery‐like stocks. We show further that some investors are themselves susceptible to sensation seeking and that sensation‐seeking investors fuel the demand for sensation‐seeking managers. While investors perceive sensation seekers to be less competent, they do not fully appreciate the superior investment skills of sensation‐avoiding fund managers.

Are Liquidity and Information Risks Priced in the Treasury Bond Market?

Haitao Li; Junbo Wang; Chunchi Wu; Yan He
Journal of Finance 2009 64(1), 467-503
We provide a comprehensive empirical analysis of the effects of liquidity and information risks on expected returns of Treasury bonds. We focus on the systematic liquidity risk of Pastor and Stambaugh as opposed to the traditional microstructure‐based measures of liquidity. Information risk is measured by the probability of information‐based trading (PIN). We document a strong positive relation between expected Treasury returns and liquidity and information risks, controlling for the effects of other systematic risk factors and bond characteristics. This relation is robust to many empirical specifications and a wide variety of traditional liquidity and informed trading proxies.

In statistics, samples are drawn from a population in a data‐generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence‐generating process (EGP). We claim that EGP variation across researchers adds uncertainty—nonstandard errors (NSEs). We study NSEs by letting 164 teams test the same hypotheses on the same data. NSEs turn out to be sizable, but smaller for more reproducible or higher rated research. Adding peer‐review stages reduces NSEs. We further find that this type of uncertainty is underestimated by participants.
