La heurística de representatividad

The representativeness heuristic is a mental shortcut people use to determine whether an event or object belongs to a certain category based on its similarity to past experiences.

Although this heuristic speeds up decision-making, it can lead to biases and flawed judgments.

In behavioral finance, the representativeness heuristic strongly influences investor behavior. 

For example, Alex invested in Alpha Corporation after observing its rapid profit growth over the past two years. 

He assumed this trend would continue without considering factors such as market conditions or future risks. 

Similarly, investors often generalize that all tech start-ups will perform well if a few have experienced rapid growth, ignoring unique risks and fundamental analysis. 

Overreliance on past patterns can lead to poor investment choices, inflated stock prices, and even contribute to market anomalies like bubbles and crashes.

Recognizing this bias can help individual investors and financial professionals make more balanced, evidence-based decisions.

Strategies such as statistical analysis and risk diversification can mitigate the impact of the representativeness heuristic, leading to more rational investment choices.
