No entanto, mesmo com diversos estudos realizados na área, a relação direta entre uma governança corporativa adequada e desempenho superior ainda é dúbia. Este trabalho tem por objetivo estudar o impacto da presença de diferentes tipos de investidores em empresas small caps na Bolsa brasileira. Para isso, utiliza-se o Q de Tobin como indicador de performance financeira e variáveis que indicam a presença ou não de investidores financeiros e não financeiros nessas companhias durante o período selecionado. O trabalho realiza o teste para dois tipos de período: o primeiro considera a presença de investidores de uma determinada natureza em qualquer momento do período testado; e o segundo considera o período específico de presença desses investidores. Os resultados obtidos não são conclusivos para estabelecer uma relação direta nos casos testados, mesmo que tenham sido encontrados alguns resultados significativos para alguns tipos de investidores em testes específicos. / The relationship between corporate governance and a firm's performance has been a widely studied theme among scholars. However, despite all the drawn to this question, the connection of appropriate corporate governance and superior performance is still dubious. This work aims to analyze the impact of the presence of different corporate and financial investors in small caps companies in the Brazilian stock market. For this purpose, Tobin's Q was selected as the key indicator of financial performance to be tested with variables indicating the presence or not of such investors. Two different types of tests were performed for this work: the first considering the existence of this kind of investor at any given period during the analyzed time frame, and the second considering the presence or not of these investors only during the specific quarters. Results were not conclusive to establish a direct relationship between these factors, despite the fact that some tests showed significant results.

量價關係，一直以來皆為技術分析學派所廣泛運用，其主張運用過去的股價以及成交量來推測股票未來的走勢，而也有許多的研究以及投資策略皆是從量價關係所出。在國內，小型股也由於其股本小的特性，往往成為有心人士炒作之標的。此外，小型股亦較大型股具有不對稱資訊的性質，而由於成交量背後往往隱藏著許多的資訊，因此投資人利用量與價之間的關係，得到能夠有效預測小型股股價的方法以利其投資。 而本文之研究，將量價關係運用在小型股上，想檢視彼此間有無任何關係存在。本文中我們使用了因果關係檢定，三因子模型，以及縱橫迴歸模型，用來分別檢視小型股與大型股的量價關係。驗證結果發現，在不同的檢驗方式下，都會得到小型股較大型股，有顯著量價影響的關係存在。 / The relation between volume and price is widely used in technical analysis. It predicts future stock price by using past stock price and volume. There are lots of investigations and investment strategies are stemmed from it. In Taiwan, small caps are preferred to be held by the people who would like to manipulate the price because of their small number of capitalization. In addition, compared with large caps, small caps are of asymmetric information to the investors. As there is lot of information hidden behind volume, investors are likely to use the relation between volume and price to get a useful way to predict small caps’ stock price. In this paper, I use granger causality test, three-factor model, and panel data model to test the relation between price/return and volume of small caps and big caps separately. The experiment shows that use different ways, we can verify there exist more obvious relations between volume and price in small caps than in large caps.
