I quite often go to find stock market proxies that might measure the significance of certain events. It helps to put bounds on things since the media generally places everything at Defcon 1 to attract attention. This rarely settles most or all questions you might have, and a lot of additional extrapolations are necessary, but can be of use.

Here is for instance, a Nuclear ETF. It might seemingly help to rule out the hypothesis of a substantial shift away from Nuclear to note that the value is in the range of just 6 months ago.
