"if I use 500 stocks, the basis is very small. i want to increase the basis in order to increase the profit.So I create my own stock index, for example, 100 stocks, long these 100 stocks and short the S&P500 index future What is the idea to create such portfolio ?"That is not arbitrage then. That is speculation. Actually pretty close to the original definition of a hedge fund. No basis (wrong term).
