Investor psychology plays a crucial role in the decision-making process. Emotional responses, cognitive biases, and psychological tendencies often lead investors to make suboptimal decisions. Understanding these influences can help individuals make more rational and informed choices.
1. Key Emotional Influences on Investment Decisions

Leads to panic selling during market downturns.
Greed
Encourages risk-taking and overconfidence, often resulting in speculative investments.
Regret
Causes hesitation or paralysis due to fear of making another mistake.
Euphoria
Drives overvaluation of assets during market booms, creating bubbles.
Example
During the 2008 financial crisis, fear led to massive sell-offs, while greed fueled speculative investments in tech stocks during the late 1990s dot-com bubble.
2. Common Cognitive Biases in Investment

Buying into a trending stock simply because “everyone else is doing it.”
Anchoring Bias
Relying too heavily on initial information when making decisions.
Refusing to sell a stock bought at $100, despite its fair value dropping to $60.
Confirmation Bias
Seeking out information that aligns with pre-existing beliefs.
Only reading bullish news about a stock while ignoring bearish perspectives.
Recency Bias
Giving undue weight to recent events while ignoring historical trends.
Assuming a bull market will continue indefinitely after a few months of strong performance.
