No way in hell.....
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.
