 In this section, I will explain the role of asset professional asset managers in selecting a portfolio. So most of the people, when we see that whenever the people have to decide that how they are going to form the portfolio in which they have to invest. So what would be the combination of the risky and the risk less assets? They have little information about the dynamics that are involved. So what they do is in order to be safe or in order to avoid different types of risks, they consult the professional asset managers to help them with the development of the portfolios. So for that purpose, the investment managers are to be hired because they are experts, they have the relevant information and they can guide the investors in a better way because they have an access to the data and the resources and the understanding also on the basis of which they can advise the investors about the best possible portfolios or the different options they can go for, the investors can go for. So what they do is they prepare the finished products and then they offer those finished products to the investors. So when we say finished products, by finished products, I mean or we mean that these are the various investment accounts that are combination of mutual funds or it could be like a combination of the bank deposits and the securities or different investment companies and insurance companies come up with different types of finished product. So those finished products are developed by the experts or the professional asset managers by looking at the various dynamics that are involved. So financially, it is basically the job of the financial experts that are hired by financial institutions and they are given this task that based upon the available information, the historical data and whatever different types of tools they know by utilizing those that information and the tools, they come up with different types of products that are, that can be offered to the investors and because every investor is different from the other and there could be a number of factors also that help the investors or that determine the investors to go for different combinations. So it is not just one type of product that is available for all types of investors. So financial institutions develop with the help of the professional asset managers, they develop different types of products for different types of customers or different types of investors. So they go for the, they make the different, they make the choices available to the households who want to invest their savings in these different types of assets or asset classes or portfolios. The selection is primarily done based upon the quantitative tradeoff between the risk and the return. So there could be a number of factors that are considered when we have to choose the portfolio or when we decide the portfolio but above all there are two basic concepts that are considered while developing a portfolio and that is a tradeoff between the risk and the expected return. So the objective of a professional asset manager is to find out that those portfolios that offer a certain category of investors the highest expected rate of return for any level of risk or any degree of risk they are willing to tolerate and we discussed it earlier that different types of people have different levels of risk tolerance. So basically what we are, what I am trying to say is that different investors are based on their age or their family's setup or their support system. On top of this, they show different levels of risk, financial risk tolerance levels. Risk tolerance means how much they are willing to bear losses, success or more. So for that we have defined three categories. So to gather the different financial risk tolerance level, maximum expected return What will you get from any portfolio? Developing these particular portfolios is the basic job or the objective of the professional asset manager.
