If you want to know how your green stock portfolio is likely to perform next quarter, you should take a look at hedge funds’ options bets.
That’s according to a newly published academic paper which looks at a decade’s worth of data from more than 1,900 hedge fund firms through 2022.
A key finding of the study is that the buildup of hedge fund managers’ put and call options on a given green equity can be used to “predict the stock’s future returns,” George Aragon, a professor at Arizona State University and a co-author of the paper, said in an interview.

The authors of the paper, titled Are Hedge Funds Exploiting Climate Concerns?, posit that hedge funds have no “nonpecuniary preferences,” meaning their green bets are only made with a fiduciary goal in mind.
The study found that hedge funds are generally better than the wider market at predicting changes
