Financial modeling is something that cannot be learnt in a day or two. It needs thorough practice before you can forecast or evaluate a business. Becoming an expert at building a financial model would take years. You can practice by taking the financials of a company, build a flat line model into the future and calculate the net present value of its share. You can then compare the current share prices and see how close your analysis was.
You must take up financial modeling courses with the experts to learn more about the subject. Get in touch with representatives at Comat. With a high reputation and experience, we are the perfect institute for the required course.
