Las finanzas conductuales se basan en la idea de que los factores psicológicos y los sesgos a menudo llevan a los inversores a tomar decisiones financieras irracionales. A diferencia de la teoría financiera convencional, que asume que las personas son actores racionales, las finanzas conductuales identifican varios sesgos psicológicos comunes que influyen en la toma de decisiones. Sesgo de Confirmación: Esto ocurre cuando los inversores buscan específicamente o favorecen información que apoya sus creencias existentes sobre una inversión, mientras ignoran evidencia contradictoria. Sesgo Experiencial (o de Recencia): Los inversores a menudo sobreestiman su memoria de eventos recientes, creyendo que es mucho más probable que ocurran de nuevo en el futuro. Esto puede llevar a una "burbuja de tres meses" donde las personas extrapolan el pasado inmediato hacia el futuro cercano.

Behavioral finance is based on the idea that psychological factors and biases often lead investors to make irrational financial choices. Unlike mainstream financial theory, which assumes people are rational actors, behavioral finance identifies several common psychological biases that influence decision-making.
Confirmation Bias: This occurs when investors specifically seek out or favor information that supports their existing beliefs about an investment, while ignoring contradictory evidence.
Experiential (or Recency) Bias: Investors often overweight their memory of recent events, believing they are far more likely to happen again in the future. This can lead to a "three-month bubble" where people extrapolate the immediate past into the near future.
Anchoring: This refers to the tendency to attach a financial decision or spending level to a specific reference point or budget level.
Mental Accounting: This is the propensity for people to categorize and allocate money for specific purposes rather than viewing their wealth as a single pool.
Historians are Prophets Fallacy: This is an over-reliance on past data to predict future conditions, failing to recognize that history is often a study of surprises and evolution rather than a set blueprint.
