Does the law of one price hold better under a flexible exchange rate system?

Using China's recent exchange rate system reform as a special event, we investigate two issues pertinent to the change in the exchange rate system: how the documented price discounts on Chinese foreign shares (B- and H-shares) changed after China shifted to a more flexible exchange rate system; and what potential factors contributed to such changes. We find significant increases in foreign share discounts after the reform and these increases cannot be explained by the changes in stock risk, information asymmetry or market liquidity. Our results provide evidence that investor expectation on long-run RMB appreciation and investor attitude toward exchange rate risk under a more flexible exchange rate system contribute to the observed increases in foreign share discounts following the reform.     

Information Asymmetry and Asset Prices: Evidence from the China Foreign Share Discount

We examine the effect of information asymmetry on equity prices in the local A‐ and foreign B‐share market in China. We construct measures of information asymmetry based on market microstructure models, and find that they explain a significant portion of cross‐sectional variation in B‐share discounts, even after controlling for other factors. On a univariate basis, the price impact measure and the adverse selection component of the bid‐ask spread in the A‐ and B‐share markets explains 44% and 46% of the variation in B‐share discounts. On a multivariate basis, both measures are far more statistically significant than any of the control variables.     

Influence of cultural factors on price clustering and price resistance in China's stock markets

This paper builds on prior research by analysing the impact of cultural factors on both price clustering and price resistance in China's stock markets. The results support the presence of cultural factors impacting on price clustering with the digit 8 showing a higher propensity for clustering and the digits 4 and 7 showing a lower propensity in the A‐share market, where stock is denominated in renminbi and traded by mainland Chinese. These results are further supported by an analysis of the B‐share market, where cultural factors have no (or less) impact on the price of Chinese stocks traded by foreign investors in US dollars (or in Hong Kong dollars). A range of measures for price resistance show the digits 0 and 5 to be significant resistance points in the A‐share market. Although digit 8 cannot be considered as a resistance point, its resistance level is highest among the remaining numbers. In conclusion, cultural factors help to explain not only price clustering in the Chinese stock markets but price resistance levels as well, albeit at a weak level.     

Sell‐Side Analyst Research and Stock Comovement

We document that a stock's price around a recommendation or forecast covaries with prices of other stocks the issuing analyst covers. The effect of shared analyst coverage on stock price comovement extends beyond analyst activity days. A stock's daily returns covary with the returns of other stocks with which it shares analyst coverage. These links between stock price comovement and shared analyst coverage are consistent with the coverage‐specific information we find in earnings forecasts; analysts who cover both stocks in a pair expect future earnings of the stocks to be more highly correlated than do analysts who cover only one stock from the pair. Collectively, our evidence indicates that analyst research produces coverage‐specific spillovers that raise price comovement among stocks that share analyst coverage. The strength of these spillovers is comparable to spillovers from broad industry and market information in analyst research.     

The Agency Effect of Repurchases on Closed‐End Funds

Share prices rise after companies announce repurchases, but there are differing views as to why this happens. Repurchases are announced by closed‐end funds when their discounts are widening (market‐to‐book is falling). The immediate post‐announcement effect is a small jump in a fund's share price, but the main effect occurs over the next four years during which time there is significant outperformance both of the fund's price and of its investment portfolio. Liquidity of the shares does not change. Repurchases, if executed, reduce the size of a fund and therefore the manager's fees. Our findings are consistent with directors using the threat of repurchases to discipline managers whose investment performance has been poor, leading to a closer alignment of pay and performance.     

Controlling Shareholders’ Incentive and Corporate Tax Avoidance: A Natural Experiment in China

The split share structure reform removes a significant market friction in China's capital market by allowing previously non‐tradable shares to be freely tradable at market prices. Such a reform reduces the agency conflict between controlling shareholders and minority shareholders as the former now care more about stock prices. We find that state‐owned firms, but not non‐state‐owned firms, significantly increased their tax avoidance activities after the reform. We attribute this differential effect to the dual role of the government as state‐owned firms’ controlling shareholder as well as the tax claimant. Further, this effect is more pronounced for state‐owned firms that are more likely to be influenced by the government prior to the reform. Finally, the reform reinforces a positive association between tax avoidance and firm value. Overall, our study suggests that when controlling shareholders are more concerned about stock prices, state‐owned firms engage more in tax avoidance activities to enhance firm value.     

Marketability,control, and the pricing of block shares

Unlike in other countries, negotiated block shares have huge discounts in China. We argue that trading restrictions help to explain this puzzle. Block shares in China face trading restrictions in the open market and can only be traded in the form of block transfers at negotiated prices. Using a dataset of 233 block transfers in China between 2002 and 2003, we find that discounts on block share prices increase with the proportion of restricted shares in the ownership. The likelihood of private benefit of control has positive impact on block prices, but the effect diminishes when there are other large shareholders. Furthermore, private institutions offer a higher price than state-owned institutions.     

A note on price limit performance: The case of illiquid stocks

In the Chinese stock markets, there are A-shares and B-shares. Both share-types have identical cash flow rights but different ownership structures (i.e., A-shares are owned by local Chinese citizens and B-shares are owned primarily by foreigners), causing B-shares to be less liquid relative to A-shares. However, even though B-shares have much wider bid—ask spreads than A-shares, both share-types are subject to the same 10% daily price limit regulation. As such, B-shares, simply due to their wider spreads, may be more inclined than A-shares to hit price limits. Our empirical results support this contention. The findings have policy implications. First, given wide spreads for illiquid stocks, exchanges may consider using midpoint prices (between bid and ask prices) to establish price limit ranges for illiquid stocks. In addition, and perhaps more importantly, exchanges may consider using wider price limits for less liquid classes of stocks.     

Was Deng Xiaoping Right? An Overview of China's Equity Markets

In the western world, stock markets arose from the search by privately owned companies for capital to build their businesses. Over time, the markets became places where ownership interests and even entire companies were bought and sold. In China, the complete opposite has happened. The markets arose out of the need for capital by bankrupt state‐owned enterprises operating in an economy with no history of private property. Deng Xiaoping, China's last emperor, gave the green light for the stock market experiment in early 1992 more with the hope of encouraging reform and efficiency than from any conviction that stock markets were the next sure thing. Now, after more than 20 years of experimentation with domestic and international listings, it appears evident that stock markets whose primary function is to trade minority interests in government‐controlled companies have not achieved the goal of improving enterprise performance, as China's leaders originally hoped. Instead, the combination of state monopolies with Wall Street expertise and international capital has led to the creation of national companies that represent little more than the incorporation of China's old Soviet‐style industrial ministries. As for the markets, the government's determination to prevent real privatization has produced separate classes of shares that are defined almost entirely by one thing: the shareholder's relationship to the government. And with all aspects of stock market activity regulated, managed, and owned by various state agencies, it is not surprising that non‐state investors have become motivated more by speculative opportunities than by investment fundamentals. But a quarter of a century is a short time in any country's development and, for all their shortcomings, the markets in mainland China and Hong Kong have played a significant role raising capital for China. It may be too early, perhaps, to suggest that China's equity markets have failed to accomplish what they were intended to do.     

Ownership Restrictions and Stock Prices: Evidence from Chinese Markets

In this paper, I test a one-period capital asset pricing model (CAPM) under share ownership restrictions to explain differences in prices and expected excess returns between the classes of shares that can be bought and traded by domestic and foreign investors, respectively, in the Chinese stock markets. I find that cross-sectional variability in the spread between the expected domestic and foreign share excess returns is related to differences in individual shares' market betas. The empirical results are by and large consistent with the CAPM. After the betas are controlled for, idiosyncratic variance and firm size have no effect.     

Short sales constraint and SEO pricing

We examine the influence of SEC's Rule 105 on informed trading and the information content of stock prices around an SEO's offer day. We show that constraints on short sales inhibit informed trading and hamper incorporation of information into stock prices for offers whose traders have private adverse information and without options listing. The constraints contribute to increased price uncertainty and higher market sensitivity to seller-initiated trading. After controlling for other causes of SEO discounts, we find that the decrease in information content of stock prices just before an offer day has a significant impact on the SEO's value discount.     

SEGMENTATION OF THE A‐ AND B‐SHARE CHINESE EQUITY MARKETS

In this study we use the latent variable asset pricing model to examine the pricing of A and B shares in the Chinese stock markets. The hypothesis tested is whether markets for the A and the B shares of the same companies are segmented. We document only one latent variable in both A‐ and B‐share markets. However, the latent risk premiums for the A and B shares are only weakly correlated, indicating the two‐tier markets are loosely related. The weak correlation implies the two markets reflect different fundamental forces. Additional analysis demonstrates that the Shanghai market responds to the Shenzhen market rather than the other way around.     

Economic policy uncertainty,investor attention and post-earnings announcement drift

How the market incorporates information into stock price is a core issue in finance. This study focuses on the impact of economic policy uncertainty (EPU) on the stock prices information efficiency of China's A-share market and underlying role of investors' attention allocation mechanism. This study analyzes the information efficiency of stock prices using the sensitivity of stock cumulative abnormal return to earnings information across different windows following earnings announcement. Based on the earnings announcement events of listed companies in China's A-share market, this study presents an empirical study of the aforementioned issues using event study and regression analysis methods. The following results are seen: (1) EPU aggravates the underreaction of stock price earnings information and the post-earnings announcement drift in the A-share market. (2) Under highly uncertain economic policies, investors show a limited attention allocation pattern of devoting increasing attention to macroeconomic policies and decreasing attention to earnings information, which leads to a decrease in the information efficiency of stock price. This study also analyzes the heterogeneity of the influence of EPU on stock price information efficiency using the institutional shareholding ratio. The results show that increasing institutional shareholding does not reduce the adverse effects of EPU on the information efficiency of stock prices. This study not only provides empirical evidence for Brunnermeier, Sockin, and Xiong (2022) and rational inattention theory, but also reveals that institutional investors show similar behavioral characteristics to retail investors in China's stock market. The results of this study have policy significance for improving the information efficiency of stock market.     

Commodity Prices and Stock Market Behavior in South American Countries in the Short Run

Using Geweke feedback measures, we present empirical evidence that largely supports the hypothesis that the stock markets of South American countries are highly affected by changes in commodity prices after controlling for changes in exchange rates, interest rates, and North American stock market changes. In total, six different Goldman Sachs commodity price indexes are tested against the unexplained variation in stock market returns for Argentina, Brazil, Chile, Colombia, Peru, and Venezuela, covering the period 1995-2007. The Argentinian, Brazilian, and Peruvian stock markets are significantly affected by changes in commodity prices the same day. Venezuela's stock market, however, does not react to changes in commodity prices, even including energy prices. Stock market returns for Chile show a contemporaneous relation with energy and metals prices, whereas Colombia's equity market is affected by price changes for agricultural and industrial metals. In all cases, we find a contemporaneous relation and no indication of a lead or lag relationship.     

Who influences the fundamental value of commodity futures in Japan?

We present evidence on the asymmetric information content of six investor groups' transactions in the gold, platinum, gasoline and rubber futures markets on the Tokyo Commodity Exchange. Microstructure theory suggests that traders with superior information regarding the efficient price should be more profitable in the long run. We find that foreign investors have the greatest influence over the efficient price in the gold market, domestic retail investors in the gasoline market and domestic investment funds in the platinum and rubber markets. Differences in the relative influence of investor groups over commodity futures are likely to reflect the degree of contract homogeneity and associated market liquidity. Foreign (domestic retail) investors have larger information shares for the homogeneous liquid (heterogeneous illiquid) contracts than for the heterogeneous illiquid (homogeneous liquid) contracts.     

The Lead‐Lag Relationship Between Cash and Stock Index Futures in a New Market

This paper investigates the lead‐lag relationship in daily returns and volatilities between price movements of the FTSE/ATHEX‐20 and FTSE/ATHEX Mid‐40 stock index futures and the underlying cash indices in the relatively new futures market of Greece. Empirical results show that there is a bi‐directional relationship between cash and futures prices. However, futures lead the cash index returns, by responding more rapidly to economic events than stock prices. This speed is much higher in the more liquid FTSE/ATHEX‐20 market. Moreover, results indicate that futures volatilities spill information over to the corresponding cash market volatilities in both investigated futures markets, but volatilities in the cash markets have no effect on the volatilities of futures markets. Overall, it seems that new market information is disseminated faster in the futures market compared to the stock market. This implies that the futures markets can be used as price discovery vehicles, providing further evidence that derivatives markets contribute to completing and stabilising capital markets in Greece. A further finding of this study is that futures volume and disequilibrium effects between cash and futures prices are important variables in the explanation of volatilities in cash and futures markets.     

The crowding out effect of booming real estate markets on corporate TFP: evidence from China

This paper explores the impact of housing price appreciation on corporate total factor productivity (TFP) in Chinese A‐share listed corporations. Results show that increasing real estate prices negatively affect corporate TFP. Meanwhile, we find that the deterring effect is especially significant for state‐owned enterprises (SOEs), large corporations and manufacturing corporations. This research further provides suggestive evidence that managerial myopia may be one potential explanation for the crowding out effect of increasing housing prices. When home purchase is under restriction, however, the negative impact of rising housing prices on corporate TFP declines sharply. This study illustrates the efficiency cost of China's booming real estate market.     

Regulatory underpricing: Determinants of Chinese extreme IPO returns

The Chinese stock market with its unique institutions is rather different from western stock markets. The average underpricing of Chinese IPOs is 247%, the highest of any major world market. We model this extreme underpricing with a supply-demand analytical framework that captures critical institutional features of China's primary market, and then empirically test this model using a sample of 1377 IPOs listed on the Shanghai and Shenzhen Stock Exchanges between 1992 and 2004. We find that Chinese IPO underpricing is principally caused by government intervention with IPO pricing regulations and the control of IPO share supplies. Besides the regulatory underpricing, this paper also documents some specific investment risks of IPOs in China's stock market.     

The impact of nominal stock price on ex-dividend price responses

In this paper, we examine whether nominal stock price can help to explain the ex-dividend day anomaly where stock prices drop by less than the dividend amount on the ex-dividend date. We find that stocks with lower nominal prices have ex-dividend day price drops that are more consistent with theoretical predictions based on an efficient market. After controlling for factors that have been previously documented to influence ex-dividend day stock price behavior, price-drop-to-dividend ratios are closer to one for lower priced stocks. To further explore this phenomenon, we examine the change in the price-drop-to-dividend ratio around stock splits. Firms that split their shares have a larger price-drop-to-dividend ratio after the split, and companies that reverse split their shares have a smaller price-drop-to-dividend ratio after the split. Our evidence indicates that ex-dividend day stock price behavior is influenced by the nominal price of a share and that this relation could also influence the decision to split a firm’s shares.     

An Empirical Analysis of Analysts' Target Prices: Short-term Informativeness and Long-term Dynamics

Using a large database of analysts' target prices issued over the period 1997–1999, we examine short‐term market reactions to target price revisions and long‐term comovement of target and stock prices. We find a significant market reaction to the information contained in analysts' target prices, both unconditionally and conditional on contemporaneously issued stock recommendation and earnings forecast revisions. Using a cointegration approach, we analyze the long‐term behavior of market and target prices. We find that, on average, the one‐year‐ahead target price is 28 percent higher than the current market price.
