🧘Investor psychology

The most common cause of poor investing outcomes is not bad stocks but bad decisions made under emotional pressure. Investor psychology studies how fear, greed and cognitive biases systematically sabotage otherwise sensible investors. Discipline beats IQ: someone with an average strategy who follows it usually does better than a clever person who sells at every panic and buys at every euphoria. Among the trickiest biases are loss aversion (a loss hurts more than an equal gain pleases), confirmation bias (we seek only information that confirms our view), anchoring (fixating on irrelevant numbers such as purchase price) and herd behavior (FOMO — fear of missing out). Panic-selling at the bottom and euphoric buying at the top are exactly the opposite of what works long-term — yet they are emotionally the strongest. The defense is a plan set in advance: entry and exit rules, position size and a trade journal that forces you to reflect on decisions. This is exactly why QMA offers a trade journal and analytical tools — not to decide for you, but to shrink the room for impulsive, emotion-driven mistakes. This section describes individual biases and practical ways to counter them.
