What can I invest in where fluctuations are highly dependent on politics?

In 2008, when I was ten years old, instead of getting a part time job while going to school, I was interested in investing. In order for me to invest as a minor, my parents opened me a custodian brokerage account, and funded it with the minimum $25,000 requirement which I paid back from my profits.

Luckily, I picked a good time to start investing. In 2008, stocks were at all time lows which are perfect buying opportunities. I decided to invest in stock industries that were dependent on politics such as gun-stocks, war-stocks, private-prison-stocks, biotech, rebuilders, energy, medicine, etc..

I noticed that when there is even a hint of some form of regulation proposals for guns, stocks surge as gun consumers go out on a shopping frenzy. Military spending, hints of war, or in times of war, or passive aerial bombings that are going on right now in the middle east, result in the surge war stocks.

As an example, I bought $1,000 shares at $2 of the publically traded gun manufacturing company Smith and Wesson. As of 2016, the gun stock corp is up to $28.50, resulting in a nearly 400% return for me within 8 years. That is just one of many stocks I invested in. In addition, some are giving 8% dividend yields.

I’m looking to invest in alternative avenues other than the stock market that are also highly dependent on politics. Any suggestions?
