Traditional finance assumes rational decisions, while behavioral finance highlights psychological biases that lead to irrational, emotion-driven choices.

Key biases include overconfidence, loss aversion, and herd mentality. 

Overconfidence bias makes traders overestimate their abilities, leading to excessive trading. 

Loss aversion causes stronger emotional reactions to losses than gains, resulting in poor decisions. 

Meanwhile, herd mentality pushes investors to follow the crowd, which can inflate prices and contribute to market bubbles.

Consider an investor, Alex. Excited by the hype around a biotech stock, he invests heavily, convinced he has unique insights. 

Encouraged by media and friends, he doubles down, ignoring warnings. 

He hesitates when the stock crashes after poor trial results, hoping for a rebound. Overconfidence, loss aversion, and herd mentality cloud his judgment, leading to costly mistakes.

Through experience, Alex learned that analyzing past trends, setting exit points, and focusing on long-term investments can make him a resilient investor. 

Recognizing biases, diversifying, and fundamental analysis help avoid mistakes and enable smarter decisions.
