comment on the following critically: When measuring performance, we tend to look at risk-adjusted metrics, such as the Sharpe ratio. The Sharpe ratio gives us a look at risk compared to the return for the given assets. For example, a high Sharpe ratio means that the returns are better than the standard, compared to the risk taken. In addition, we may also look at other comparisons such as the standard deviation, volatility, or maximum drawdown. Determining "better" is can vary from person to person, but typically "better" means the highest returns possible for the lowest potential risk. Diversification helps us achieve "better" because it removes some of the volatility associated with single asset performance. Correlation is used to measure the diversification and risk profile of a portfolio. These range -1 to +1, with the whole numbers symbolizing perfect negative or perfect positive correlations. The closer a portfolio is to 1, the less diversified it is, leading to a larger window or risk
