I think yes but today Bitcoin has another split called Segwit2x and it's more popular than Bitcoin Cash. I can't really say regarding the possibilities that Bitcoin Cash may par Bitcoin's price but I think Segwit2x will be more than what we're expected.
It will be the same as the bitcoin cash, the only important thing that the bitcoin needs segwit 2x to make the ridiculous fees will be reduced a lot in the future. How so many people are paying a lot just for a single transaction. I hope that will be happening and then the bitcoin cash users will be moving towards the bitcoin blockstream again.
