I am trying to address the above. If I take say the ETF SLV (Silver) against it's 2 x leveraged ETF AGQ. If I want to create a pair trade which is dollar neutral does that mean the following:
Say we want to buy SLV & Sell AGQ
SLV @ £20
AGQ @ $40
Amount to invest on both sides is $10,000
Number of shares to buy in SLV = 10000/20 = 500
Number of shares to sell in AGQ = 5000/40 = 125
I guess it boils down to. If you have a 2 times ETF do you invest only half the amount in that share? i.e. that dollar neutral in this case is £10,000 on one side & £5,000 on the other?
