If you ever wondered what the primary motivator is for Americans buying guns - you now have some good data: the stock prices of publicly traded gun manufacturers.

What you see here is the result of an October and November run-up because it looked like Hillary Clinton would win the election. The second that Trump was elected, their shares got crushed, and they've been hammered hard ever since then.

So what drives sales? Fear. Fear that those Democrats are going to take away all of the guns.

It will be interesting to see if this trend continues deep into a Trump presidency.
