Does reading financial statements (quarterly or annual reports) really help investing?
Reading and analyzing financial statements is one of the most important tasks of Equity Analysts which look at a company from a fundamental perspective.  However, analyzing a company and its financial statements is much more than just reading the absolute dollar figures provided in financial statements: You need to calculate financial ratios which can be compared over multiple periods and companies to be able to gauge the development of a company over time and compare it to its competitors. For instance, for an Equity Analyst, the absolute dollar figures of a company's operating profit is less important than the ratio of the operating profit to revenue, which is called the operating margin.  Another very important figure is Free Cash Flow which can be set in relation to sales (= Free Cash Flow / Sales).  The following working capital related metrics can be used as a health check for a company and give you early warning signs when they deviate too much: You can either calculate those metrics yourself using a spreadsheet (e.g. Excel) or use a professional solution, e.g. Bloomberg Professional, Reuters Eikon or WorldCap.
