John makes the following statements during a discussion of his financial plans with an investment adviser. (a) I use the internet extensively to research the stock market every day, and I believe now is the best time to invest in the energy industry. (b) I have earned good return from investing in the stock of company ABC over the last year, and I am sure it will be a better performer in the future. (c) I do not want to sell the stock for a price lower than I bought it. Identify and explain concepts of behavioural finance consistent with the statements. Do you think that these concepts have much impact on investor behaviour in the real world?
