I am not one, who after an event, tries to explain why something may have happened as is the case with most economists, politicians and post analysis traders. I tend to view things the other way around and look at why something has not happened such as you telling us the markets would crash and then didn't. I look at the supposed variables that people convince themselves are contributing but on anaylsis there is no evidence for, (ie markets rallying because four Bexiters were sent packing etc) is completely lacking any evidence at all to the rally we have seen because the rally was already happening and consistently before this happened.
I am not really interetsed in finding the variables / reasons as to why it has rallied and I appoached trading in the same way. I know this is counter intuitive to how most people do things but then most people lose money and are wrong in their predictions as to what is likely to happen.
The issue with the internet is that it is very easy to find some evidence to support any view on any subject and that applies as much to markets, economics and politics as anything else. The real skill is in knowing how to discount or disprove something as it is much more effective than the alternative of finding evidence to support something in my view.
