In a series of my studies, I find that the benefits of trading financial derivatives may outweigh the costs of doing it because hedging protects investors and individuals from extremely adverse situations. I find that hedging home prices by housing derivatives could be better than not hedging at all, especially during the 2008 financial crisis. One reason could be enhanced public information production from financial analysts. I find that information is more efficiently disseminated to the public by analysts after equity option listing.
