Exam 2 Flashcards
Risk Return trade off
The greater the risk, the greater the potential return
assumption about investors
they are averse to risk (dont like)
Formula for interest
Principle * interest * fraction of a year
Formula for return in $
amount received - amount invested
Formula for return in %
Return in $ / amount invested
Alt names for return in %
rate of return / expected return
Required rate of return
the minimum acceptable potential return given the risks
Decision rule
expected return must be greater than required return for people to invest
Formula for expected return in dollars
take each scenario and multiply return by weight, add the products to get the total
Formula for expected rate of return
Return in $ / Amount Invested
Efficient Portfolio
provides either greatest expected return or least risk relative to amount invested
Calculate expected portfolio return
% holding * return expected for all holdings then added together
objective of portfolio construction
to invest in assets whose prices are non or negatively correlated
company specific risk
derived from events specific only to a company
alternate names for company specific risks
diversifiable risk
nonsystematic risk
market risk
derived from events that affect all/most investments in the marketplace
alternate names for market risk
nondiversifiable risk
systematic risk
which risk does diversification mitigate
only company specific
MPT
Modern Portfolio Theory - investors want to max return and manage risk
Discount Rate
rate charged to financing operations for businesses
Present Value
the amount if invested today will grow to a specified amount by a specified date
To compound or discount more or less frequently than annually you
Divide interest by number of terms and multiply periods by number of terms
When is each annuity paid
Ordinary - at the end of each period
Annuity Due - at the beginning of each period
Amortizing Loan
borrower pays principal and interest, loan balance is zero at maturity, highest payment
Non-amortizing loan
interest only loan
borrow pays interest only, loan balance is the principal at maturity, medium payment
Negative Amortizing loan
borrow pays less than interest, loan balance is greater than principal at maturity, lowest payment
Formula to determine amortization payment
FV = PV(1+i)^n
FV is always 0
Uneven cashflows
find the present value of each of the sums and then add together (divide PV by (1+i)^n)
Formula to determine interest portion of amortization payments
principal * interest * fraction of a year. for subsequent years use the principal - payments for principal
