Introduction:
Investing in different assets is a risky and challenging task of finance market. It is generally practiced with the concept of how much risk an investor is willing to take.

Therefore, by approaching risk in this way—rather than always buying the safest investments— is being influenced by what's called modern portfolio theory, or sometimes simply portfolio theory. While it's standard practice today, the concept of minimizing risk by combining volatile and price-stable investments in a single portfolio was a significant departure from traditional investing practices.
In fact, modern portfolio theory, for which economists Harry Markowitz, William Sharpe, and Merton Miller shared the Nobel Prize in 1990, employs a scientific approach to measuring risk, and by extension, to choosing investments. It involves calculating projected returns of various portfolio combinations to identify those that are likely to provide the best returns at different levels of risk (FINRA,
