The stock market and investment

Changes in stock prices have substantial explanatory power forU.S. investment, especially for long-term samples, and evenin the presence of cash flow variables. The stock market dramaticallyout-performs a standard q-variable because the market-equitycomponent of this variable is only a rough proxy for stock marketvalue. Although the stock market did not predict accuratelyafter the crash of October 1987, the errors were not statisticallysignificant. Parallel relationship for Canada raise the puzzlethat Canadian investment appears to react more to the U.S. stockmarket than to the Canadian market.     

Corporate investment and stock market valuation

We study the driving forces behind the positive association observed between corporate investment and stock market valuation, and how they interact with managerial equity incentives and informativeness of investment. We build a dynamic model where managers use investment choices to influence investors' opinions about firms' future prospects and increase the market valuation. The incentives to manipulate the valuation processes increase with managerial equity incentives and informativeness of investment. Our empirical findings support the model's predictions that the tendency of using investment to boost market valuation is stronger when managerial stock ownership is high or when earnings quality is low (i.e., there is strong reliance on investment for information).     

Responsible investment in the Chinese stock market

This paper provides insights into the current development of responsible investment in the Chinese stock market. We find that responsible investment can bring portfolio benefits to investors, and institutional investors have a holding preference for stocks in responsible investment indexes. By using a national air pollution proxy, we find that investors’ pessimistic mood on days with heavy air pollution has a negative influence on the stock return of A-shares, while stocks in responsible investment indexes display improved performance over the same time period. We use aggregated trading data to study the trading preference of Chinese retail investors on days when they are influenced by air pollution, and find that their total trading ratio shows a negative influence for both A-shares and responsible investment indexes. Moreover, there is more seller-initiated trading of the whole sample but more buyer-initiated trading of stocks in responsible investment indexes on air pollution days. This finding is consistent with the different stock return performances of these two samples. Our finding extends the studies of responsible investment to emerging markets and presents new evidence about the influence of environmental factors on trading behavior and return performance.     

Government real estate interventions and the stock market

We study the spillover of government interventions in the real estate market to the stock market. We find that the more active mutual funds decreased ownership in equities with no short-term reversal. Furthermore, they increased ownership in the finance sector stocks without significant changes to their real estate equity holdings. The interventions affecting the riskiness of the finance sector stocks triggered a larger trading response than the ones focused on the real estate sector stocks’ cash flows. Overall, the spillover of the housing market shocks to the stock market seems to be materialized mostly through the discount rate channel.     

Global portfolio investment network and stock market comovement

This paper examines the impact of financial connectedness of countries on international stock market comovement. In recent decades, cross-border capital flows have increased dramatically, and I use bilateral cross-border portfolio holdings to create a global portfolio investment network. Using network analysis, I examine the effect of a country's centrality within this network on stock market comovement while also controlling for the country's trade connectedness. The results show that stock markets of countries that occupy highly central positions within the global portfolio investment network exhibit higher comovement after I control for the level of trade connectedness. Countries that simultaneously occupy highly central positions in both financial and trade networks display even higher levels of stock market comovement. Moreover, linkages derived from total portfolio holdings matter just as much as or more than those derived only from equity linkages.     

Managerial characteristics and stock market investment: evidence from China

We examine the effect of managerial characteristics on investment in the stock market by listed firms in China. Our empirical findings suggest that higher levels of cash‐based compensation may increase both the propensity of investing in the stock market and the total amount of investment. On the other hand, managerial holdings discourage managers from investing in stock markets and also lead to a decrease in the amount of investment. This study sheds light on managerial risk‐taking incentives. Moreover, this study fills the gap in the literature by providing evidence for the determinants of listed firms’ stock market investment.     

Dynamic volatility spillovers and investment strategies between the Chinese stock market and commodity markets

Building on the increased interest in the volatility spillover effects between Chinese stock market and commodity markets, this paper investigates the dynamic volatility spillovers of Chinese stock market and Chinese commodity markets based on the volatility spillover index under the framework of TVP-VAR. The result shows that there is a highly dependent relationship between the stock market and commodity markets. On average, the Chinese stock market is the net recipient of spillover, non-ferrous metals and chemical industry have a very obvious spillover impact on the stock market. The degree of total volatility spillover is different in different periods. After major crisis events, the volatility correlation between markets increases. Since the outbreak of COVID-19, the spillover effect of the stock market on the commodity market has been significantly enhanced. Then optimal portfolio weights and hedge ratios are calculated for portfolio diversification and risk management. The result shows that the ability of most commodities to hedge against risks is significantly reduced when the crisis occurs; NMFI (precious metals) and CRFI (grain) still have good hedging ability after the crisis, but the effectiveness of hedging risk is relatively low. Besides, the combination of CRFI and SHCI (the Shanghai composite index) is the most effective for risk reduction.

The incremental information content of employee reports for stock market investment decisions

The practice of preparing and issuing Employee Reports to an organization's work force is now well established throughout many countries. A survey of companies listed on New Zealand's stock exchange (Firth and Smith 1984, p. 5) indicated that about 22% of responding companies produced Employee Reports. These Employee Reports often contain data that are not present in the firm's Annual Report and Accounts, and this has potential usefulness to stock market investors. If Employee Reports do have usefulness to stock market investors, then this raises policy issues about current disclosure requirements to shareholders. In particular, it heightens concerns about whether the shareholders are being given timely and adequate information. In order to test whether Employee Reports do have any incremental information content, an abnormal returns analysis on 88 reports was carried out. The results showed no evidence of abnormal returns, and so the incremental data contained in Employee Reports either have no usefulness for investors and/or the information has been discounted from other sources.

退市与破产

公司退市在中国一直是个大总是,从ST到PT,千方百计地,公司都要采取不同的形式,坚持在股市上继续挣扎。退市只是流于形式而已。同样,中国的公司也不愿意破产,特别是国有企业,有政府在背后撑着,必要时就政策扶植,实在不行了还会出面帮助重组。为了保证社会稳定,就是不能让企业破产。那么,中国的这种现状还有什么深层次问题吗?说到底,中国的企业不愿意退市、破产是与我们的文化背景有密切关系的。请看     

Sanctions and the Russian stock market

The article presents the robust estimates of extreme movements and heavy-tailedness properties for Russian stock indices returns before and after sanctions were introduced. The obtained results show that almost for all sectoral indices there was a statistically significant increase in volatility. At the same time there is not enough evidence of structural breaks in heavy-tailedness, though some indications of heavier both right and left tails in the post-imposition period can be observed for some indices. However, we cannot with complete certainty directly link the increase in heavy-tailedness with the imposed sanctions. The latter to a considerable extent could be caused by higher country-specific risks due to geopolitical tensions as well as oil prices volatility. Whatever is the cause, any increases in heavy-tailedness can have grave consequences for corporate management, economic modeling and financial stability analysis.

Firm value and investment policy around stock for stock mergers

We study a sample of publicly traded firms that expand by acquiring other firms in pure, stock-for-stock mergers. After these mergers, we find that the diversification premium decreases for the acquiring firm due to having added a target firm trading at a discount. Furthermore, the acquiring firm experiences a decrease in investment opportunities and a decrease in leverage. This is an effect confined only to non-diversifying mergers. Our results indicate that the acquirer’s investment efficiency at the firm level remains unchanged after the merger.     

Privatization and stock market liquidity

This paper shows that share issue privatization (SIP) is a major source of domestic stock market liquidity in 19 developed economies. Particularly, privatization IPOs have a negative effect on the price impact – measured by the ratio of the absolute return on the market index to turnover. This result is robust to the inclusion of controls for other observable and unobservable factors, having also considered the endogenous nature of the decision to privatize.     

Economic forces and the stock market revisited

The pricing of the Chen, Roll, and Ross (CRR) macrovariables is re-examined and found to be surprisingly sensitive to reasonable alternative procedures for generating size portfolio returns and estimating their betas. These methods include the full-period post-ranking return approach used in many recent studies. Strong evidence of pricing is obtained only for their industrial production growth factor and, in another contrast, for the VW market index. In particular, the corporate-government bond return spread, an important factor in CRR, is insignificantly negative for the 1958–1983 period, corroborating the cross-sectional regression results.     

Cyber-attacks and stock market activity

I study how financial markets react to unexpected corporate security breaches in the short and the long-term. The main results show that daily excess returns drop, trading volume increases due to selling pressure, and liquidity improves upon the public disclosure of first-time corporate hacking events. The evidence from the search frequency in Google suggests that such short-lived market reaction is due to increasing investors' attention. Cyber-attacks affect firms' policies in the long run, up to five years after the security breach announcement. These results are consistent with the hypothesis that security breaches represent unexpected negative shocks to firms' reputations.     

Investor sentiment and the near-term stock market

We investigate investor sentiment and its relation to near-term stock market returns. We find that many commonly cited indirect measures of sentiment are related to direct measures (surveys) of investor sentiment. However, past market returns are also an important determinant of sentiment. Although sentiment levels and changes are strongly correlated with contemporaneous market returns, our tests show that sentiment has little predictive power for near-term future stock returns. Finally, our evidence does not support the conventional wisdom that sentiment primarily affects individual investors and small stocks.
