## What is Portfolio Optimization?
Portfolio optimization is the method of choosing the best portfolio (asset allocation) from a selection of all possible portfolios to be considered in order to achieve the objective. Typically, this process seeks to maximize the factors, such as expected return, while minimizing the factors, such as expenditure, volatility, and risk. The ideal portfolio varies and is informed by the return expectations and risk tolerance of each individual investor.
Portfolio optimization mostly takes place in two stages: optimizing the weights of asset classes and optimizing the weights of securities in the same asset class. Optimizing asset class weights would require decisions, such as determining the percentage of portfolios put in equities vs bonds or real estate.
Whereas, an example of security selection would include deciding precisely which securities or bonds are to be held. Holding some of the portfolios in each class provides for some diversification, and having various common assets within each class allows for more diversification.
