After six years joining the world trade organization (WTO), Vietnam has enjoyed a lot of merits from its economic global integration; However it also faced with many challenges. In line with the broader achievement, banking sector regime has evolved quickly. The stock price of banking sector has always been an important issue for investors. This study uses four models as price-earnings ratio model, price-sales ratio model, market - to - book ratio model, and discounted cash flow model to present valuation of stocks in vietnamese banking industry: a case study for Asia Commercial Bank. The empirical results reveal the valuation based on price-earnings ratio model, price-sales ratio model and discount cash flow model are unreasonable. And the expected share price in the market - to - book ratio model is the most reasonable.
