The Center for Studies in Finance (GVcef) of São Paulo School of Business Administration (FGV/EAESP) has presented a survey that indicates a growth of approximately 250%, between 2002 and 2013, of the assets invested in the thousand largest funds open to financing in the Brazilian market. The rate is much higher than the 40% evolution of the country's economy.Based on the data for June each year, the amount of money invested, according to GVcef, increased from BRL 188.72 billion to BRL 657.57 billion - and exceeded the money invested in savings, which totaled BRL 538.45 billion.In the same period, the number of fund managers that manage these investments increased 82%, from 83 to 151. The average net equity per administrator of BRL 2.27 billion also increased until 2006, and declined until 2009, and has been increasing ever since. In June, it reached BRL 4.35 billion - the highest for the month according to the survey.For GVcef's coordinator, William Eid, the study's data relate to the increase in the efficiency of fund managers, which today generate more wealth. In addition, he emphasizes that this growth has stimulated greater diversity in the industry. What we observe is that the smaller fund managers have been looking for market niches?, he says.
