Finance can be defined as follows:-
(A) It is a study of the valuation and
(B) It is a study of the management of risk

The components of risks are two which are mention below:-
(A) The time of its revelation
(B) The nature of its randomness

The debt can be short term and is called a Treasury Bill, which will promise a given cash flow within the next year. A treasury bill is the typical example of a risk-free security, there is no uncertainty about future payments.

A long term debt is usually over a year and is typically issued as government bonds, with annual coupons payments and when bond reach at maturity level a repayment of the face value at the bond maturity.

There are generally two types of financial markets
(A) Futures markets are markets where one can fix a price today for future delivery of some good
(B) Options markets are markets where one can fix a price today for a future contingent delivery of some good

The price of a basket (Quantity of financial elements and their present value) of financial contracts is the sum of the prices of each individual contract multiplies the quantities in each contract.

It should be practically impossible to sell a product for a positive price a portfolio which has no payoff for all future payment. This principle is known as the “no arbitrage” assumption. In other words, if replicating portfolios have the same price is known as the “no arbitrage” principle.

The value of the firm can be calculated by adding value or price of each component which comprises the asset. So in other words corporation or firm consists of different assets. After adding all assets, the value of firm is derived.

The firm is held by a number of different creditors, such as bondholders, equity holders, banks and so forth. The value of the creditor’s holdings which is known as liabilities and it must by value additivity and no free lunches add up to the value of the firm.

The value of the firm equals the sum of the values of the company’s liabilities to the traditional creditors. If the liability consists of debt value B and equity E so firm value V is mentioned below
V = E + B

In 1970 The Efficient Markets Hypothesis by Eugene Fama can be defined as the Information is always correctly reflected in securities prices. However this statement is difficult to understand because the vast meaning of the word “information” and the word “correctly reflected”.

Information sets are usually categorized in the following three sets:-
(A) All (private and public) Information
(B) Public Information
(C) Past Prices

Information sets are usually categorized in the following three sets:-
(A) All (private and public) Information
(B) Public Information
(C) Past Prices

When a corporation declares its quarterly earnings and the income/earnings are twice what the market expected, the corporation’s stock price should rise.

There are many types of companies and funds. In these companies, Closed-end mutual funds are considered as regular companies whose sole purpose is to invest or purchase other share.

Options give the right to sell (put) or purchase (call) an underlying asset at a pre-determined price (the strike price) during a particular period.

Correctly Reflected means that markets use the available information with them in the best possible way for its assessment of the current value of a financial security

In financial markets, the rule of Conditional probability must be satisfied in case of learning is rational. The conditional probability can be defined as the probability of an event B that the event will occur given that an event A has already occurred.

Bad news in the market will push the prices of a financial instrument or assets down, the historical (ex-post) returns go down, but the expectations based on the current price are not affected.

A basic unit of account in finance is a set of future cash flows. Following are two important properties of these cash flows:-
(I) The amounts
(II) The dates at which the amounts are paid

A US Government Treasury bill pays USD 1000 263 days from now. Today’s value of one dollar received 263 days from now is USD 0.945. The Present Value of the Treasury Bill is
PV = 0.945 x 1000 = 945.

In finance, the rate of return on finance can be defined as
Rate of return = {(Payments during period + Value at end of period) / Value at beginning of period} -1

Rate of return = interest rate = {(Payments during period + Value at end of period) / Value at beginning of period} -1
Payment during period =100
Value at end of period = 8
Value at beginning = 100
So put these values in formula
Interest rate = {(100 + 8)/100}-1= (108/100)-1=1.08-1=0.08=8 percent

The Net Present Value (NPV) of an investment project is the difference between the Present Value and how much it costs you to generate the same cash flows (with your project). It means by taking this project, profit will be earned.

Net present value can be calculated by subtracting the initial cost of the project from present value so
Net present value = PV – Initial cost of the project =2511.6 + 3000 = -488.4
And if NPV<0 or in negative values, it clearly suggests us as undesirable project

Net present value = Present Value of the project – Initial cost of the project
So if NPV gives us negative value, the following can be an effect of the negative NPV
(I) NPV < 0 (II) This is not a profitable project, Don’t invest (III) Avoid investing in this project, as it will cause a major loss

Capital budgeting is used for the following:-
(I) The valuation of investment project
(II) Management of investment projects
(III) Invest in any project with a positive Net Present Value

Net present value = Present Value of the project – Initial cost of the project
So if NPV gives us positive value, following can be effect of the positive NPV
(I) NPV > 0
(II) This is a profitable project, so invest in this project
(III) Positive NPV reflects the presence of economic rents

A perpetuity can be defined as a sequence of payment for unlimited duration in future time. Or in other words, it is simply an annuity with no end.
