Remember, to calculate risk/reward, you divide your net profit (the reward) by the price of your maximum risk. Using the XYZ example above, if your stock went up to $29 per share, you would make $4 for each of your 20 shares for a total of $80. You paid $500 for it, so you would divide 80 by 500 which gives you 0.16.

What is value at risk?
Value at Risk (VaR) is a statistical measure used to assess the level of risk associated with a portfolio or company. The VaR measures the maximum potential loss with a degree of confidence for a specified period. For example, suppose a portfolio of investments has a one-year 10 percent VaR of $5 million. Therefore, the portfolio has a 10 percent chance of losing more than $5 million over a one-year period.

What is standard deviation in investing?
It indicates how much the current return is deviating from its expected historical normal returns. For example, a stock that has high standard deviation experiences higher volatility, and therefore, a higher level of risk is associated with the stock.

Beyond the particular measures, risk management is divided into two broad categories: systematic and unsystematic risk.
What is risk return trade off?
One of the principles of investing is the risk-return trade-off, where a greater degree of risk is supposed to be compensated by a higher expected return. Risk - or the probability of a loss - can be measured using statistical methods that are historical predictors of investment risk and volatility.
What is the R squared measure?
R-squared is a statistical measure that represents the percentage of a fund portfolio or a security's movements that can be explained by movements in a benchmark index. For fixed-income securities and bond funds, the benchmark is the U.S. Treasury Bill. The S&P 500 Index is the benchmark for equities and equity funds .

Standard Deviation
Sharpe Ratio
- The Sharpe ratiomeasures investment performance by considering associated risks. To calculate the Sharpe ratio, the risk-free rate of return is removed from the overall expected return of an investment. The remaining return is then divided by the associated investment’s standard deviation. The result is a ratio that compares the return specific to an investment with the associ…
Beta
- Beta measures the amount of systematic risk an individual security or sectorhas relative to the entire stock market. The market is always the beta benchmark an investment is compared to, and the market always has a beta of one. If a security's beta is equal to one, the security has exactly the same volatility profile as the broad market. A security with a beta greater than one means it i…
Value at Risk
- Value at Risk (VaR)is a statistical measurement used to assess the level of risk associated with a portfolio or company. The VaR measures the maximum potential loss with a degree of confidence for a specified period. For example, suppose a portfolio of investments has a one-year 10% VaR of $5 million.
