Volatility is how much and how quickly prices move over a given span of time.
In the stock market, increased volatility is often a sign of fear and uncertainty among investors.
SPDR S&P 500 ETF (SPY) had 180-Day Historical Volatility (Close-to-Close) of 12.78%.
Ideally a portfolio should have lower volatility than S&P due to diversification.
It’s a measurement of how the portfolio moves with respect to S&P 500.
A correlation of 1.0 indicates a perfect positive correlation.
Goal of diversification is to reduce a portfolio’s alignment with the index.
Therefore, a correlation lower than 1(or 100%) is desirable.
CAGR, which stands for "Compound Annual Growth Rate," is a metric used in the stock market to
calculate the average annual growth rate of an investment over a specific period,
taking into account the effect of compounding, essentially showing how much a stock has grown
on average each year over a set timeframe, assuming profits are reinvested throughout the period.
Below is a table of S&P 500 CAGR:
The Sharpe ratio compares the return of an investment with its risk.
The Sharpe ratio can help explain whether a portfolio's excess returns are attributable to smart
investment decisions or simply luck and risk.
A Sharpe ratio of 1 or higher is generally considered good,
2 or higher is very good, and 3 or higher is excellent. 10-year historic S&P 500 Sharpe Ratio is 0.89
Unlike the Sharpe ratio, the Sortino ratio only considers returns that fall below a predetermined threshold,
making it particularly useful for investors concerned primarily with downside risk.
A higher Sortino ratio indicates a better risk-adjusted return for a given level of downside risk.
A Sortino ratio of 1 or higher is generally considered good
"Value at Risk" (VaR) is a statistical measure that estimates the maximum potential loss an
investment or portfolio could experience within a specified time frame, at a given confidence level.
Typically calculated at 95 level, it indicates a confidence of 95% that the portfolio
won’t underperform more than a certain percentage.
