Quote from ItermBonds:
Thanks for mentioning this. What I meant was in the context of timing. Say if you bought one of these leveraged ETF's and it tanked on you by $40 because you bought it at $100; you would have a much better chance at buying something like FAS in the $2 or $3 range if we were close to a "bottom" -- that is considering in the first place you wanted to take on this kind of risk.
If you're sensible enough to buy FAS at a short-term bottom you would have never bought FAZ near it's short-term top.
