Is it possible for all the owners of a stock to gain or lose money at the same time?
Take the case where a stock has just two owners, A and B, both at $10. One of them sells his shares to C, at $11.  Now B has made $1 in profit but is no longer an owner of the stock. A hasn't sold anything but his shares are worth 10% more due to the last traded price printed. C has bought shares at $11 and the price is $11, so technically he hasn't lost any money. In a larger market, there are winners and losers every day on a single stock, but they may not remain owners of a stock. There could be days in which those that remain owners are all winners - say when a stock goes up to an all time high and all those that are currently owners have an average buy price lower than the last traded price. And the reverse applies too.  It is of course more complicated. Say you own a stock and let someone else "borrow" it for a short-selling opportunity (he sells it in the market). For each uptick in price, you win, the short seller loses, and the guy he sold it to also wins. A person that has a covered call on a stock is not a winner beyond a point. And so on.
