The above is a graph of the Deutsche Bank stock value and just an example of the many stocks that are currently tumbling down '2008 style' which remarkably coincides with the release of the movie 'The Big Short'. The movie is about savvy bankers/hedge funders who know how to take advantage of a crashing financial market. I bet the same will be happening again when the next crisis will hit us ; another and perhaps final transfer of 'wealth' or what was left of it since 2008 from the populace to the oligarchs.
Add to the falling stock prices the low levels of the Baltic Dry Index, an economic indicator which shows you an assessment of the price of moving the major raw materials by sea.
So in short: simply place your bets on plummeting stock prices.
