If you can time it perfectly (e.g. directionality is constant), then UWT or GUSH are 3X crude ETFs. The 3X means you are exposed to decay so the return won't be as good if it goes down then up.

This is also assuming either ETF exists come Monday. The rapid drop (>30%) could mean the products are ended.

In that case it may be worth getting long-term XOM (or other petroproducer) calls.
