If it looks like the potential shutdown will be accompanied by an economic downturn, buy some. SPXS. It is an 3 X inverse ETF of the S&P 500. Look at the chart on yahoo yourself and see what it does when the market crashes. You will not be disappointed or hurt if the stock market has a large negative correction. It is an excellent hedge against this type of thing. I have 1000 shares. if the market really goes bad it will be worth 1/4 million. If it does not I might lose 1000 bucks. Pretty good risk/reward.
SPXS shorts stock?
Yes I agree if there is little enforcement I would expect widespread resistance. However I expect enforcement is the entire point of the exercise since it definitely is not public health. The powers that be are looking to see who the trouble makers are.
good advice - $$$ talks, Lead works, all else is B.S.
