Estrategia de Debilidad Post-Festiva

La Debilidad Post-Festiva es la tendencia de los precios a caer inmediatamente después de un festivo importante cuando el volumen sigue siendo escaso. Con muchos participantes aún ausentes, los movimientos contra tendencia pueden ganar fuerza.

Las pruebas indican un retorno anual promedio de aproximadamente el 112%. Funciona mejor en el mercado de forex.

La estrategia vende en corto el día después del festivo y cubre rápidamente una vez que regresa la participación normal.

Se usa un stop pequeño para evitar pérdidas excesivas durante la negociación con baja liquidez.
