In terms of portfolio investment targets, the types of the United States in the world are relatively "complete". In the United States, securities portfolio can be divided into income type, growth type, mixed type (mixed income type and growth type), money market type, international type and indexation type, tax avoidance type and so on. The first three are more important.

The income combination pursues the maximization of basic income (that is, interest and dividend income). The securities that can bring basic income are: interest-bearing bonds, preferred stocks and some tax-avoidance bonds.

The growth portfolio aims at capital appreciation (that is, the spread income brought by future price increases). Growth portfolios often choose securities with low risks and high returns relative to the market, or with returns proportional to risks. Securities that meet the criteria of growth portfolio generally have the following characteristics: ① income and dividends increase steadily; ② The income growth rate is very stable; 3 low dividends; ④ The expected income is high; ⑤ The total income is high and the risk is low. In addition, it is necessary to conduct in-depth and detailed analysis of the enterprise, such as product demand, competitors' situation, operating characteristics, company management status and so on.

The mixed portfolio of income and growth tries to achieve a certain balance between basic income and capital growth, so it is also called balanced portfolio. The balance between the two can be achieved through two combinations, one is to balance the income-generating securities and growth securities in the portfolio, and the other is to choose those that can bring benefits and have growth potential.

Currency market portfolio is composed of various money market instruments, such as treasury bills and commercial bills with high credit ratings, which are highly secure.

It is the trend of portfolio management that international portfolio invests in different overseas countries. The empirical results show that the performance of this portfolio is generally better than that of the portfolio that only invests in local countries.

Indexed portfolio simulates a certain market index, and institutional investors who believe in efficient market theory usually prefer this portfolio in order to obtain the average market income level. According to the different simulation indexes, the indexed portfolio can be divided into two categories: one is to simulate a broad market index, and the other is to simulate a special index, such as the Dow Jones Public Utilities Index.

Tax-exempt portfolios usually invest in municipal bonds, which are exempt from federal taxes and are usually exempt from state and local taxes.
