LEAPS bear call spreads on:
Del Monte (FDP)
Ford (F)
Or, (safer idea) use the butterfly strategy to catch movement either up or down, depending on whether dear orange leader and the governing party take a symbolic victory or actually set up trade barriers.
Overall, I'm not sure this theme is worth exploiting. It's a year-old rumor at this point.
The long-term effect of trade barriers will be price increases and a reduction in demand, both due to deadweight losses. There are also other political blunders in the queue that will be inflationary - immigration reductions, about 3 wars, and tax cuts for starters. If you want to bet on inflation, you could set up a synthetic long on TIP, USO, or GLD (although GLD is not actually tied to inflation). Also, get the eff out of bonds if you, like Janet Yellen, think inflation is coming.
I'm looking at the whole zeitgeist and shifting most of my portfolio to a collared position in SPY.
