What you think of this strategy?
Market goes down 10% (or 15%): 1x ETF (SPY, DIA)
Market goes down 20% (or 30%): 2x ETF (SSO, DDM)
Market goes down 30% (or 45%): 3x ETF (BGU)
Since market needs to go down 50% or 33.33% in one day (it can't because of futures daily trading limits) you are blowup protected.
Yet, you can still wath your account fluctuate down (temporarily) a lot.
