Equations Flashcards
Conversion Price formula
PAR/shares
Conversion Value formula
Convertible Shares * Price of stock
Coefficient of Variation (CV) formula
standard deviation/mean expected avg return
Coefficient of Variation (CV) description
- compares two assets with different average returns
- higher CV = riskier
- riskier = less likely investor will achieve average return
risk/return
Risk Adjusted Return description
- opposite of CV
return/risk
Covariance (COV) description
- measure 2 securities combined and their interactive risk
- measure of related risk
Correlation Coefficient (p) description
- ranges +1 to -1
- risk is reduced when correlation < 1
Covariance (COV) formula
(Correlation)(Std Dev1)(Std Dev2)
Correlation Coefficient (p) formula
Coefficient of Determination (R-Squared) description
- how much return is due to the market
Coefficient of Determination (R-Squared) formula
p^2
- squaring correlation coefficient (p)
Capital Market Line formula
Capital Asset Pricing Model (CAPM) description
- single factor model
- calculates relationship of risk and return of individual security using BETA
Capital Asset Pricing Model (CAPM) formula
Portfolio Risk description
- measured through determination of interactivity of the standard deviation and covariance of securities in portfolio
- utilizes weight of both securities, deviations, and correlation coefficient
Portfolio Risk formula
Information Ratio (IR) formula
Information Ratio (IR) description
- relative measure (compare to other IR)
- rank high to low
Treynor Index (Tp) formula
Treynor Index (Tp) description
- uses Beta as denominator
- relative measure (compare to other Treynor)
- measures reward achieved to level of systematic risk
- standardizes portfolio returns for volatility
Sharpe Index (Sp) formula
Sharpe Index (Sp) description
- if no r^2, always use Sharpe
- uses standard deviation as denominator
- relative measure (compare to other Sharpe)
- measures risk premiums of portfolio relative to total amount of risk in portfolio
Investor seeking to invest in single fund should select fund with highest ___ ratio
Sharpe Ratio
Arbitrage Pricing Theory (APT) description
- multifactor model
- attempts to take advantage of pricing imbalances
- inputs include factor like inflation, then specifics including expected returns and sensitivity to the factors
- standard deviation and beta are NOT inputs
