Are traders 100% responsible for a stock's price changes?
Value is the key word here. Traders should ideally trade on the perceived future value of a company.  Changes in the perceived future value is what leads them to buy and sell shares. That said, if a company were to have some catastrophe happen (say it and all of its employees and property disappeared)  and somehow every shareholder agreed to not sell, the companies market capitalization would remain unmoved even though the value of the company is gone. So theoretically yes, but it is unlikely.
