Intro. To Business
Broadly investment bankers (investment banking firms) perform three functions, Investigation, Analysis and Research (Origination), Underwriting (Public Cash offerings) and Distribution. Most of time a single investor banker performs all functions, however some investment bankers are specialized in certain functional areas only. From the way an investment banker works, it sounds to me like it could be a lazy way of handling your investments, investing and your cash flow. If given the right skill set, and Investment Banker could turn your zero cash flow into millions, or the opposite.
The Stock Market is the market in which shares are issued and traded either through exchanges or over-the-counter markets. Also known as the equity market, it is one of the most vital areas of a market economy as it provides companies with access to capital and investors with a slice of ownership in the company and the potential of gains based on the company's future performance.
If wisely invested and played correctly the stock market can be a very gainful attempt. If wisely investing, you must look into the future, and the past. A wise investor knows market fluctuations and can call them for future reference.
