Investment decision making usually has two steps
A: Investment banking and security analysis
B: Buying and selling
C: Risk and expected return
D: Security analysis and portfolio management

Investment decision making traditionally includes security analysis and portfolio management. Security analysis means studying stocks or bonds to judge their value and risk. Portfolio management means combining different securities to maximize return and reduce risk. For example an investor may analyze company reports and then create a portfolio of shares bonds and mutual funds. These two steps help investors make informed decisions and achieve financial goals.
