An investor buys a share of stock by resorting to various approaches that validate his investment by reaping rich profits. Before investing, however, it is necessary for a value investor to study the financials of a business, so that the stock he buys at the company’s intrinsic value promises a greater return at its liquidation value (the value of a company if all its assets were sold). A typical investor would buy growth stocks that have an upward trend, and seem likely to keep growing for a long time. Whereas, a technical investor (also known as a Quant) makes decisions based upon the psychology of the market and related factors, which involve much higher risk but may prove to be more profitable, or, can conversely result in much greater losses. The fundamental analysis of any business can depend on various factors: efficient market theory, value and growth, growth at a reasonable price and the quality of the business.
