Mutual funds have allowed specialized investment in different areas to enable the participants (shareholders or investors)to revceive higher income without making major financial or economic movements. At present the use of mutual funds is one of the most common financial activities, as these have high rates of return in a short time, it is worth mentioning that the above is specifically based on a specific type of fund, but the profitability and obtained participation in this type of action allows mutual funds hold a great attraction especially for people interested in national and international investment. Hear other arguments on the topic with Ben Silbermann . Thanks to the large share held by mutual funds now in the economic and financial aspects of a person, region or country they can be classified into different types and each of them provides investors as the various qualities applied area of investment, some of these types of mutual funds are: equity mutual funds or shares: these are funds specializing in obtaining large revenues (profitability) in relatively short periods of time making it a great way to get good yields economic, but it is very important to mention the downside to this type of fund, as the risk also plays an important role, because these are funds exposed to a constant change in the value of the shares, giving investors the chance to double your income quickly or lose it almost completely. Fixed Income Funds: These are specialized funds to obtain the economic returns to medium time periods or long, because the investment of these funds are safer than equity investments, because they only invest in constant growth markets and somewhat slow. The main advantage that has this kind of investment is that the certainty of obtaining performance is almost fixed, but is not comparable with the yields of short-term equity fund. Mutual fund mixed (fixed and variable) are investments that are made taking into account the risk and return can be obtained either from a fixed or variable, however in this fund is more cautious decreasing the risk of lost without lowering returns can be obtained, so the risk is very limited, so the profitability is also limited. It is important to mention that this is probably the most widely used form of investment today because the profitability and risk reduction variable offered to investors. Given this demonstrated that mutual funds are a great way to invest our capital, either to increase in a short or long term so the best approach before making an investment is to go where someone skilled in the art, in order this person can properly advise to get a better return on investment desired.
