A stock’s “price” is basically the lowest price that people are willing to sell it for. Imagine a stock is selling for $50, many people want it, and someone tries selling it for $40. It sells immediately, and the lowest price remains $50. Now imagine no one wants it, you go to sell it for $45, and still no one buys it. This causes the price to go down to $45. Generally speaking, a stock price going down means more people want to sell it than want to buy it.
