Rebalancolást

Rebalancolást is a theoretical concept often discussed in speculative finance and behavioral economics. It describes the psychological tendency of individuals to disproportionately adjust their portfolios or holdings after a significant perceived shift in value, rather than making gradual, systematic adjustments. This behavior can manifest as an overreaction to market volatility, leading to decisions that deviate from a pre-defined strategy.

The term suggests a departure from rebalancing, which typically involves regularly adjusting an investment portfolio to maintain a desired asset allocation. Instead, rebalancolást implies a more dramatic, often emotionally driven, overhaul triggered by substantial price movements or news events. For instance, an investor might sell a significant portion of an asset that has experienced a rapid decline, or conversely, heavily invest in an asset that has seen a sudden surge, irrespective of long-term fundamentals.

This phenomenon is believed to stem from cognitive biases such as loss aversion, herd mentality, and recency bias. Loss aversion might cause investors to exit positions quickly to avoid further perceived losses, while herd mentality could drive them to follow popular market trends. Recency bias can lead to an overemphasis on recent price action, overshadowing historical data or future projections. Understanding rebalancolást is crucial for developing robust investment strategies that resist emotional impulses and maintain discipline in the face of market fluctuations.
