In a hypothetical situation there are 2 Stocks A and B which have perfect correlation and change in real time. Since they change in real time, there is no opportunity for arbitration. In this case what would be the best neutral strategy (with or without futures). And what would be the advantages of that strategy compared to long strangle of single stock.
the best strategy is to do nothing and go to the beach. There’s no opportunity in something that is perfectly correlated with something else
newwurldmn is correct. The only way to make money on a perfectly correlated pair is at order entry with an exit plan that does not eat into your profit. E.G. Buy XYZ.B and short XYZ.A where .B is convertible into .A and you buy .B at a discount. Or, buy an ITM warrant at a discount to parity that is convertible into the common and then short the common. Then exit by conversion.
