Assuming we're talking about foreign investors. Quite simply that's going to depend on the policies, not whether Xi is in there or not.

As a party dictatorship with routinely transitioned politicians, China's government has been fairly stable in recent times. Xi clearly isn't necessary in any regard, he's trying to make himself necessary. Hu Jintao was a stable leader that oversaw one of the fastest economic expansions in world history. He also wasn't necessary, in terms of remaining perpetually in power. Xi inherited that nicely built-up economic position. It's the policies that Xi follows/implements that will determine investor confidence, just as it was for Hu Jintao and Jiang Zemin (also a stable leader that didn't need to remain in power perpetually). Xi is properly replaceable like the others, insofar as he doesn't implement political changes that forcibly make him otherwise. The power move that Xi appears to be going for, is all down to his personality, rather than necessity, which is in stark contrast with the prior two Presidents.
