If you are actually trying to take your account to zero owning leveraged ETF's would be a fantastic way to do so. Leveraged ETFs are designed to track the intra-day movement of the underlying basket not to track the leveraged returns of the index they reference on a historical basis (ie greater than a few weeks). The error associated with daily rebalancing ensures that all of these leveraged funds will eventually become worthless, and this is strongly worsened if they track futures that are heavily contango. I would strongly consider staying away from leveraged ETFs at all costs, unless you plan on holding them for under a week.
