Which are common mistakes people make when investing? Choose four correct answers.

Focusing heavily on familiar investments can lead people to overlook better opportunities and take on too much concentrated risk. Investing more than you can afford and putting all your money into one kind of investment are also common mistakes because they can expose you to losses you cannot manage. Holding onto a losing investment too long just to recover its losses can also hurt your results. Dividing money among investments with different risk levels and considering your comfort with risk are generally sensible practices, not mistakes.
