👉 Percentual is a mathematical concept used in finance, particularly in investment analysis and risk management. It represents the proportion of an asset's value that has changed over time relative to its original value. In other words, it measures how much money or assets have increased or decreased compared to their initial amount. For example, if you invest $100 in a stock that increases by 25% each year, and then sell it after one year, the percentage change would be 25%.
