The debate rages on. Cramer has been concerned and raising interest in this again as we have been watching the continuation of the very unusual trading after 2pm daily.

Tighter regulations? Well, perhaps… but this is a must watch at least to hear Jeff Macke’s comment as he related the double-inverse ETFs to strippers….
