Understanding the difference between price and value in the stock market is crucial. Price is the payment made, while value is what is received. The stock market serves as a tool for investors to determine the worth of assets. In the short term, the market operates like a voting machine based on speculation, but in the long term, it functions as a weighing machine, providing a more accurate assessment of an asset's value. To succeed in the market, one must discern the true value of assets and leverage this understanding to make informed investment decisions.
