<p>This study contributes to the on-going studies on behavioral finance by providing a case study on underreaction and overreaction of firm stocks to firm valuation. We use the Model of Investor Sentiment (Barberis et al., 2005) to evaluate underreaction and overreaction behavior and reflect on specific findings in the Indonesian market. The result of the study is most of the stocks in the Indonesian Stock Exchange are more overreaction to the news of firm financial statements. Firms on the industry with more intangible assets measure more overreaction than firms on industries with more tangible assets. For stocks with overreaction, the stock firm value is positively affected by a change in the total assets and profitability, but not by change of book value. The result concretized no evidence that firm stocks overreacted to the news more than underreacting. In stock industrial sectors, the financial institutions and wholesale industry stocks demonstrated remarkable overreactions. Nonetheless, automotive, building construction, food and beverage as well as cement evidenced more underreaction. For better return in financial markets, investors may buy stocks of the firm on industry with more tangible assets when there is no good news about the increasing firm profitability and sales; nonetheless, they should buy stocks of the firm on industry with more intangible assets when there is no lousy news about the increasing firm profitability and sales. </p>
