Risk-risk refers to variability of expected returns associated with given investment.
Return-Return, is the amount of money receive from an investment.
Expected return- R1×P1+R2×P2……Rn×Pn
Relationship risk and return -Higher risk is associated with greater probability of higher return
and lower risk with a greater probability of smaller return.
Standard deviation:, the standard deviation is a measure of the amount of variation or dispersion of
a set of values. the smaller the standard deviation ,the tighter the probability distribution and thus the
lower the risk of investment. Formula- σ 2 = √r −rbar square × p
❑
Variance- The variance is the average of the squared differences from the mean. Variance formula-
Types of Risk:
Business Risk-business risk is the risk by fluctuations of earnings before interest and taxes.
Types-compliance risk, financial risk, reputation risk
Liquidity Risk-liquidity risk is the risk that a company or bank may be unable to meet short term
financial demands. example: account receivable, bank deposit, debt terms
Default risk - default risk is the risk that a lender takes on the chance that a borrower will be unable
to make the required payments on their debt obligation. example-strategic default, consumer default,
sovereign risk .
Market Risk-Market risk is the risk of losses in positions arising from movements in market prices.
Example: changes in equity prices, interest rate moves or foreign exchange fluctuations.
Interest Rate Risk: Interest rate risk is the risk that arises for bond owners from fluctuating
interest rate .example- if interest rates rise bond prices fall.
Purchasing power risk: purchasing power risk, is the risk that inflation reduces the value of an
investment. example: when rise in price will reduce the quantity of goods that can be purchased with a
fixed sum of money.
Chapter-08
Capital budgeting-is the process of making long term planning decisions for investments.
Example: payback period, accounting rate of return, net present value, discounted payback period.
Internal rate of return, provability index.
Discounted payback period- The discounted payback period is a capital budgeting
procedure used to determine the profitability of a project. FORMULA= Discounted Cash Inflow =
Actual cash inflow / (1 + i) n
Discounted pay back period -pros and cons—pros-i)consider the time value of money. ii)
considers the riskiness of the project cash flows. Cons-i)may reject positive npv investment.calls
for a cost of capital
Payback period- The payback period refers to the amount of time it takes to recover the cost of an
investment. FORMULA=total cash outlay ÷ average annual cash. Year before full recovery+unrecoverd
cost at start of the year/cash flow during the year.
Payback period-pros-i)simple to compute .ii)provides some information on the risk of the
investment. Cons - i)Ignores the time value of money .ii)ignores the risk of future cash flows.
Npv- Net present value (NPV): is the difference between the present value of cash inflows
and the present value of cash outflows over a period of time. Formula-total present value –
initial investment.
