What kind of existence is finance

When it comes to finance, most people may reflexively think of “Wall Street”, “investment banking”, and financial people often say “Financial Modeling”.
Among them, Financial Modeling is a very high level for many laymen. So what kind of existence is this “Financial Modeling”?
What are Financial Models?
In a nutshell, Financial Modeling is the calculation of various reference values (such as the commonly used indexes) over a period of time by adding, subtracting, multiplying and dividing, which is used for investment analysts to write reports or research.
But not only the four operations is very simple and low, behind the fact that involves a lot of logical judgment, exchange rate conversion, time difference conversion, each point in time corresponding to the value of storage.
Someone once compared modeling to the process of “distilling coffee”.
The coffee beans are “10K/10Q/SEC Fillings”;
The grinding tool is a software or language such as Excel sheet;
The extract is the final thesis, i.e. the investment view.
