Quote from hii a_ooiioo_a:
Again, I know essentially nothing about Pairs Trading and need to learn a lot. But here's a thought, tell me if it may be worth considering:
If you took two neutral positions in two different stocks, for instance buying February NVSL & selling March NVLS, while buying March AMAT & selling February AMAT, you would have two different pairs trades set up on NVLS and AMAT, and your margin would be 40:1 until you closed out one pair, because the two AMAT would offset each other, and the two NVLS positions would offset each other.
So that, while you had both sets of pairs open, your margin would be 1/4 for the two pairs what it would be for one pair, and also you wouldn't have to fret about which stock should be the short leg and which should be the long leg, since you would have created both arrangements.
For the same price (except commissions) as entering a pairs trade of 1 NVLS contract & 1 AMAT contract, you could have one pairs trade of 4 NVLS & 4 AMAT, plus the reverse pairs trade of 4 more AMAT & 4 NVLS.
