"Tighter" can have a HUGE effect, if one trades Listed Options. SELL time if NO $$$$$ to exercise ( OR - at any stage before Exercise DATE ) can create HUGE price movements
CVI is Nov 09 ( as is 09 , PRU and MXROA )
Unless one DESIRES to exercise some, or ALL ( listed )options, one should stay aloof.
RISK?????? v's Gain?????? - It IS weighable.
