The stock market hates dirty air - The Boston Globe

The stock market hates dirty air - The Boston Globe:
"Analyzing daily index returns from several stock exchanges over a 10-year period, the authors of the study found that stock returns were generally lower on days with poor air quality ratings in the vicinity of the stock exchange. The effect is significant: Trading stocks based on day-to-day air quality ratings might have allowed you to beat the annual return on the S&P 500 by several percentage points."
if you are looking for the paper it is here from ScienceDriect.

Similar findings to this paper from last year's paper that found the same type thing in Milan. But I cannot find it. Will try to look after the pool. :)
