You see a stock that has risen 80% in the past 12 months and decide to buy it mainly because of that strong recent performance.
Most investors believe they are rational, disciplined, and informed. Yet decades of research in behavioral finance and market data show that the majority repeatedly fall into the same traps: chasing past performance, trying to time the market, ignoring costs, overreacting to short-term news, and underestimating the power of compounding and diversification. These blind spots are not signs of low intelligence; they are normal human tendencies that systematically erode returns. This quiz presents 40 realistic situations and decisions that everyday investors face. For each one, decide whether the action or belief is sound. The questions stay at a practical, intermediate level—no advanced formulas required—focusing on principles supported by long-term evidence from markets, academic studies, and investor-behavior research. Score yourself honestly. The results will reveal how many of the most common, costly mistakes still shape your thinking. Ready to see your blind spots clearly?
