Beta Coefficient
The formula to calculate the Beta coefficient is:
Beta (β) = Covariance (Ri, Rm) / Variance (Rm)
Where:
- Ri = a stock's return
- Rm = overall market's return
- Covariance = ups & downs of stock returns versus ups & downs of market returns
- Variance = the difference between market returns and its average
Generally, Beta values are of four types:
- Beta < 1.0: stock less volatile than the market
- Beta = 1.0: stock just as volatile as the market
- Beta > 1.0: stock more volatile than the market
- Negative Beta: stock shares inverse relation with the market

Average True Range Atr
The formula for ATR is:
ATR = Previous ATR (n - 1) + True Rangen / n
n= number of periods
True Range = The greater/highest of these:
- High - low (Day 1)
- Absolute value of (Day 1’s high - Day 0’s close)
- Absolute value of (Day 1’s low - Day 0’s close)
Carrying Charge
A carrying charge can increase the cost of owning an asset. At times, the cost of carry may exceed the potential returns, in which case an investor must evaluate whether the asset is worth keeping.
