Yes..it might be a good time to buy VXX now..but i would not buy a lot of shares as SPX might have some more up to finish this run..i would start the VXX with 100 shares..then add another 100 if SPX rises more next week..going up to a max of 400 shares
if SPX falls next week you can also buy VXX..but instead of 100 buy 200..but again..i would not add too much until SPX comes back below PMH
it is all relative..how much do you want to try and make..how long are you going to give it..and how much are you willing to risk
just so you know..there are plenty of other symbols to trade..much lower cost..some will have smaller moves..some will have bigger moves..you must know how much it will move before you make your decision
i done up this table tonight for another thread..i will now modify to track these symbols automatically..and assign the correct share size based on the average daily ranges..in effect..i will be working backwards..so..instead of me looking to make a gain of 300%..i will let the symbol tell me what my target gain should be for my risk %..then I can automatically set my correct share size for my desired risk level
