Summary The relationship between air pollution and the share price of local companies is investigated using company-level data in China. We explored the relationship between air pollution, stock returns, and the commercial performance of local companies using company-wide data. Finally, we build a company-level index to measure the mood of individual investors caused by air pollution in China’s stock market.
We have already seen that air pollution affects the stock price of the Chinese stock market mainly due to internal bias. Therefore, we are saying that if there are temporary and internal factors, such as air pollution, affecting the A-share market, it is not suitable for the efficiency of the market. Therefore, studying only the relationship between the market index and air pollution in the cities where the exchanges are located could lead to severe biases.
The stock index’s performance reflects the level of air pollution in Shanghai and other cities where the companies included in the market index are located. Air pollution in Shanghai may not significantly affect the performance of the SSE index. The sensitivity of stock returns to air pollution is much broader for high growth stocks, distressed stocks, and increased volatility stocks. In the Chinese stock market, characterized by a large area and order-oriented trading, the impact of air pollution in the city where the stock exchange is located on the performance of market indices seems to be levelling out, requiring a better method to include the prospective home bias.
For every increase in the standard deviation of pollution, the stock market performed 12% worse. Every time air quality dropped by one standard deviation; stock returns dropped by 12%. We compared the stock index stock index’s performance at the EPA stations near Wall Street, but also with the average performance of Manhattan stations, and came up with the same result.
The result was the same no matter where in the other city they measured the pollution. When University of Ottawa economics professor Anthony Hayes and colleagues compared daily S&P 500 data with daily air quality data from an EPA sensor near Wall Street, they found a link between higher pollution and lower stock returns.
When air pollution exceeds 15 micrograms per cubic metre, it’s a pretty chaotic day, with speeches by Canadian lawmakers scoring much lower on language. But, for example, we know that animals that breathe polluted air can fight more than animals that breathe clean air.
The pollution control industry is booming from reducing greenhouse gas emissions from industrial power plants to minimizing your car’s exhaust emissions. Rising water prices and new regulations for the production of mercury from coal-fired power plants in the US fuel the success of some pollution control companies.

New sulphur regulations have opened up new opportunities for the purification industry in the form of exhaust gas purifiers, and Donaldson appears to have the most efficient option on the market today. In addition, the pollution control industry is one that responds when legislation calls for increasing the amount of certain harmful chemicals that can be released into the environment.
