are traders 100% responsible for a stock's price changes?

yes traders, living or algorithmic, are the only direct factors that can cause a change in the price of a marketable item. traders can be affected by news, broken exchanges ;), emotional cycles, lunar cycles, time the trader goes to lunch (or a power cycle if you are an algo running on that unfortunate os), anything.
