Why not just short an ETF that tracks the financial sector.... can't think of the name now, it's very volatile.
SKF is looking jummy right about now. http://stockcharts.com/h-sc/ui?s=SKF&p=D&b=3&g=0&id=p28825147897 Very volatile though. In fact, it's rare to see a combination of such high liquidity and long-term volitility. We are talking penny stock level here. Any other ETFs like this?
