Finance is a term for matters regarding the management, creation, and study of money and investments.
Specifically, it deals with the questions of how an individual, company or government acquires money – called capital in the context of a business – and how they spend or invest that money. Finance is then often split into the following major categories: corporate finance, personal finance and public finance.At the same time, and correspondingly, finance is about the overall "system"
i.e., the financial markets that allow the flow of money, via investments and other financial instruments, between and within these areas;
this "flow" is facilitated by the financial services sector.
Finance therefore refers to the study of the securities markets, including derivatives, and the institutions that serve as intermediaries to those markets, thus enabling the flow of money through the economy.A major focus within finance is thus investment management – called money management for individuals, and asset management for institutions – and finance then includes the associated activities of securities trading and stock broking, investment banking, financial engineering, and risk management.
Fundamental to these areas is the valuation of assets such as stocks, bonds, loans, but also, by extension, entire companies. Given its wide scope, finance is studied in several academic disciplines, and, correspondingly, there are several related professional qualifications that can lead to the field.
Hello everyone,
I did my studies and finished my master's in natural sciences, only to find out that the ground is too shaky and jobs/prospects are scarce. Also, after long term unemployment, I lost a little my interest in academic work. Since I have a second degree in business administration...

This equation takes a present value (PV) to find mortgage payments, PMT:
Alternatively, switching V for PV and T for PMT:
V/T = r(1-r^n)/(1-r)
What is an algebraic method to solve for "r"?
Can it not be solved for? I realize I can just find out "r" by trial by error in Excel using the PMT...

Dear all,

Hello.
There is a financial metric called time weighted rate of return, which is computed using the following formula:

r tw = (1+r1) x (1+r2) x...x (1+r nth year),
where r tw is the time weighted rate of return...
Physics is one of the hardest discipline to master. Yet physics graduates, on average, have a tougher time finding jobs and very often earn less than finance/engineering graduates.
Why do you guys do this to yourself? Are you masochists? Do you enjoy pain?
