Inverse and 2x, 3x ETFs: Massive, massive tracking.
You should not hold an inverse for more than a short term (days, not weeks) trade. Triple inverses tend toward zero in the long run. Look at FAZ 5 year chart. Notice this equity assasin ETF FAZ managed to fall like a knife even as the financials were falling. Thats right, an inverse ETF with a direct correlation to the underlying assests. Oy vey.
As for 3X, compare FAS 3x long to unlevered XLF over 5 years. A chart of sadness.
These are radioactive vehicles that should be handled with care and suspicion.
