El retorno esperado es un concepto clave en finance and investing, representing the anticipated return on an investment or asset over a certain period. It is calculated as the weighted average of all possible returns, where the weights correspond to the probabilities of each outcome occurring. This metric helps investors make informed decisions by providing a snapshot of potential gains or losses based on historical data and market conditions.
Para calcular el rendimiento esperado, generalmente se utiliza la siguiente fórmula:
Retorno Esperado (E[R]) = Σ (Probabilidad de Resultado * Retorno del Resultado)
In this equation, each possible return from an investment is multiplied by the probability of that return occurring, and then all these products are summed. The expected return can be positive, negative, or zero, depending on the investment’s risk profile and market dynamics.
El retorno esperado es particularmente importante en gestión de carteras and asset allocation, as it allows investors to gauge the risk-return trade-off of various investments. However, while it provides valuable insights, it is essential to remember that expected return is not a guarantee of future performance; actual returns can be influenced by numerous unforeseen factors, including market volatility, economic changes, and company performance.
