To explore what kinds of roles foreign investors take in a gradually opening financial market, we propose the abnormal holding value ratio (AHVR) of northbound investors among stocks through China’s Stock Connect Mechanism. We find that AHVR positively predicts the expected stock returns and significantly relates to firms’ quality-related fundamental information, especially profitability. Foreign investors learn the firm fundamentals before they invest in the Chinese market, which is different from the trading behavior of domestic individual investors. The AHVR premium is larger among firms with higher attention of analysts who focus on effective information and with lower attention of individual investors who have behavioral bias. In all, the northbound inflows are smart money, which will increase the efficiency of the Chinese market instead of simply chasing stars that only grab investors’ attention.

We empirically investigate the relation between anomaly portfolio returns and market return predictability in the Chinese stock market. Using 132 long-leg, short-leg, and long-short anomaly portfolio returns, we employ several shrinkage-based statistical learning methods to capture predictive signals of the anomalies in a high-dimensional setting. We find statistically and economically significant return predictability using long- and short-leg anomaly portfolio returns. Moreover, high arbitrage risk enhances forecasting performance, supporting that the predictability stems from mispricing correction persistence. Unlike the U.S. stock market, we find little evidence that the long-short anomaly portfolios can help predict market return due to the low persistence of asymmetric mispricing correction. We provide simulation evidence to sharpen our understanding of the differences found in the U.S. and Chinese stock markets.

We explore whether Management Discussion and Analysis (MD&A) can provide incremental information to peers. Using Chinese stock market data, we find that positive peers' MD&A tone encourages firms to hold more cash, particularly for industries with fewer institutional investors' site visits. Moreover, this association is moderated by predation risk and decision-making environment. Specifically, this effect is more pronounced for firms which are market followers or financial constrained, and it is also stronger for firms operating under higher economic policy uncertainty or solely in domestic market. Overall, our findings enrich the information channels of peer effects in cash policy.

The inelastic markets hypothesis states that the aggregate stock market price elasticity of demand is small, implying that flows have large impacts on prices. We exploit demand shocks created as investor funds are frozen and unfrozen during Chinese IPOs to estimate the impact of demand shocks on the Chinese stock market. Using brokerage account records, we observe the selling and buying as investors raise cash to subscribe for IPOs and then reinvest the funds that supported unsuccessful subscriptions. Using an instrumental variables estimator we find that a 10 bps demand shock increases stock prices by between 30 and 48 bps.

Using a proprietary dataset from 2016 to 2019, we find that order flows from foreign investors, facilitated by regulatory liberalization through several channels, present strong predictive power for future stock returns in the Chinese market. Most surprisingly, foreign investors possess the ability to process local firm-level public news, whereas their informational advantages regarding global market-level information are relatively muted. Further, the predictive power of foreign investors is particularly strong on large price movement days when the implications of firm-level information is likely most pronounced. Finally, regulatory reforms that generally relax investment access requirements further improve foreign investors’ predictive power

After the Chinese stock market dropped one-third in three weeks in June 2015, reportedly driven by lack of liquidity due to the fire sales by margin buyers, the government used hundreds of billions of dollars to purchase shares directly in the secondary market. We validate that margin trading is associated with the surge of stock market before the crisis. We find that firms in systemically important industries, firms with more political ties, and firms with high risk of falling into liquidity spiral are more likely to be rescued. More importantly, compared with matched un-rescued firms, rescued firms did not have higher stock return, but experienced higher volatility, lower liquidity, and lower price efficiency afterwards. Market quality even deteriorated further after the subsequent sale of the purchased shares. Last, rescued firms experience a modest decline in operational performance, while capital structure and investment remained the same. Our evidence suggest that a direct purchase rescue in the secondary stock market could generate serious unintended consequences.

Stock market trading restrictions affect stock prices and liquidity directly through constraints on investors’ transactions and indirectly by altering the information environment. We isolate this indirect effect by analyzing how stock market restrictions affect corporate-bond prices. Exploiting the staggered relaxations of trading restrictions in the Chinese stock market as a quasi-natural experiment, we document that the easing of trading restrictions on a firm’s stock decreases the credit spread of its corporate bond. This effect is stronger for firms with less transparency or lower credit ratings. Our evidence suggests that the effect is likely due to improved stock price informativeness.

This paper studies the trading behavior of investors facing a large number of firm-initiated stock trading suspension events during the Chinese stock market crisis in July of 2015. Using account-level trading data from the Shanghai Stock Exchange, we find that investors with a higher fraction of holding value in suspension sell less (or purchase more) of non-suspended stocks. Consequently, non-suspended stocks whose shareholders having high average account- level suspension fraction experience a relative price appreciation, which subsequently reverses. These evidences indicate that trading suspension can calm down investors and therefore helps to stabilize the volatile market in crisis time.

Abstract: Traditional research about the passive investors and index were mainly focus on the tracking error and the performance of mutual funds. However, they ignored that, deceptive by name, the passive investors, such as index-tracking funds and ETFs, may have an active impact on the value of the company through large-scale transactions of these passive investors. Focused on the Chinese stock market, this paper investigates whether specific passive investors, the funds and ETFs that track MSCI China index, will actively influence the market valuation after MSCI Index Rebalance. When the passive shareholders, which are always the mutual funds, exceeds a threshold, I find that firms added to the index will have a significant positive return, about X%, to the index itself. Also, I find the firms eliminated out to the index have a significant negative return, about X%, to the index itself. One potential interpretation of these results is that index-rebalancing will lead the index-trackers to buy those stocks added to the index, and these transactions represent a large buy power that will lead the demanding of those stocks to exceed the selling power and this dynamic of trading plus the following transactions of other investors eventually cause a premium and positive return. The firm size will also have an impact on stock performance when the index get rebalanced, partially in that the weight of the index is calculated according to the market value, a calculate method that leads to the higher weight of large companies. If large companies are added to or removed from the index, the trading volume will be larger, causing more transactions dynamic on those stocks.
