What kind of drop in the S & P are you anticipating? I can see into the 2040 range as that would close some gaps from last June... but to close those gaps from the beginning of the year would be be quite dramatic( but the low 1800s doesn't seem impossible). I just don't see TVIX ever trading in the $225 - $300 range, which is where it be if the S&P dropped to fill those early in the gaps. Back in 2011, this moved over a 2 month period, about 800% from its Aug low, but even then, it never went over $80-90 at its top if I recall correctly.
