❓ Frequently Asked Questions
What is Behavioral Finance in the context of stock markets?
Behavioral finance studies how psychological factors influence investor decisions, causing biases and deviations from rational models that can shape market prices.
What is loss aversion and how does it affect trading?
Loss aversion is the tendency to fear losses more than equivalent gains, leading to risk-averse behavior, holding losers too long, and selling winners too soon.
What is herd behavior and why does it matter in stock markets?
Herd behavior is copying others' actions rather than relying on independent analysis; it can fuel trends, bubbles, and abrupt price moves.
How do anchoring and overconfidence influence stock decisions?
Anchoring sticks to a reference price, causing slow adaptation to new information; overconfidence leads to excessive trading and underestimated risks.
How can investors mitigate behavioral biases when answering quiz questions or trading?
Use structured rules and checklists, diversify portfolios, verify with objective data, pause to reflect on potential biases, and review decisions systematically.
