Why are some Chinese Firms Failing in the US Capital Markets? A Machine Learning Approach

Pacific-Basin Finance Journal,
We study the market performance of Chinese companies listed in the U.S. stock exchanges using machine learning methods. Predicting the market performance of U.S. listed Chinese firms is a challenging task due to the scarcity of data and the large set of unknown predictors involved in the process. We examine the market performance from three different angles: the underpricing (or short-term market phenomena), the post-issuance stock underperformance (or long-term market phenomena), and the regulatory delistings (IPO failure risk). Using machine learning techniques that can better handle various data problems, we improve on the predictive power of traditional estimations, such as OLS and logit. Our predictive model highlights some novel findings: failed Chinese companies have chosen unreliable U.S. intermediaries when going public, and they tend to suffer from more severe owners-related agency problems.
Limited Investor Attention and the Mispricing of American Depositary Receipts
I test whether more investor attention leads to a better exploitation of arbitrage opportunities and, in turn, to less mispricing of American Depositary Receipts (ADRs). Using data on 536 stocks I find that more investor attention significantly reduces ADR mispricing.
Are European Equity Style Indices Efficient? – An Empirical Quest in Three Essays
Schriften des IWH,
Many situations in the history of the stock markets indicate that assets are not always efficiently priced. But why does it matter whether the stock market is efficiently priced? Because “well-functioning financial markets are a key factor to high economic growth”. (Mishkin and Eakins, 2006, pp. 3-4) In three essays, it is the aim of the author to shed some more light on the topic of market efficiency, which is far from being resolved. Since European equity markets have increased in importance globally, the author, instead of focusing on US markets, looks at a unified European equity market. By testing for a random walk in equity prices, revisiting Shiller’s claim of excess volatility through the means of a vector error correction model, and modifying the Gordon-Growth-Model, the book concludes that a small degree of inefficiency cannot be ruled out. While usually European equity markets are pricing assets correctly, some periods (e.g. the late 1990s and early 2000s) show clear signs of mispricing; the hypothesis of a world with two states (regime one, a normal efficient state, and regime two, a state in which markets are more momentum driven) presents a possible explanation.
Systematic Mispricing in European Equity Prices?
IWH Discussion Papers,
One empirical argument that has been around for some time and that clearly contra- dicts equity market efficiency is that market prices seem too volatile to be optimal estimates of the present value of future discounted cash flows. Based on this, it is deduced that systematic pricing errors occur in equity markets which hence can not be efficient in the Effcient Market Hypothesis sense. The paper tries to show that this so-called excess volatility is to a large extend the result of the underlying assumptions, which are being employed to estimate the present value of cash flows. Using monthly data for three investment style indices from an integrated European Equity market, all usual assumptions are dropped. This is achieved by employing the Gordon Growth Model and using an estimation process for the dividend growth rate that was suggested by Barsky and De Long. In extension to Barsky and De Long, the discount rate is not assumed at some arbitrary level, but it is estimated from the data. In this manner, the empirical results do not rely on the prerequisites of sta- tionary dividends, constant dividend growth rates as well as non-variable discount rates. It is shown that indeed volatility declines considerably, but is not eliminated. Furthermore, it can be seen that the resulting discount factors for the three in- vestment style indices can not be considered equal, which, on a risk-adjusted basis, indicates performance differences in the investment strategies and hence stands in contradiction to an efficient market. Finally, the estimated discount rates under- went a plausibility check, by comparing their general movement to a market based interest rate. Besides the most recent data, the estimated discount rates match the movements of market interest rates fairly well.
