The stock exchange is a marketplace where buyers and sellers can meet to trade stocks and bonds. The demand for a stock or bond is partially determined by the current movements in the market, as investors need to make informed decisions about which assets to buy and sell. As demand for a stock or bond increases, its price increases. Conversely, if the market conditions favor selling the security, its price to potential buyers decreases. Similarly, in the pharmacy, the prices of prescription drugs are determined by market conditions. The demand for various prescription drugs affect their prices, as do the availability and popularity of each drug. The pharmacist must monitor these market changes to determine the best time to fill orders, just like the stockbroker monitors market changes when filling orders. In both cases, pricing is determined by the laws of supply and demand.
