What are your financial goals for 10, 15, or 20 or more years down the line, and how do you plan on getting there? What is your level of risk tolerance, and what sort of investment approach will you take (value investing, dividend investing, or some combination of multiple strategies)? As you consciously outline your financial goals and the type of investor you want to be, you can experience success as a disciplined investor in the long run and stay on track with your plans.
To make comparisons between companies, sectors and markets a little easier, there are a number of mathematical models used. The most common and often the most helpful is the P/E ratio.

Using an independent trading platform you don’t have to relearn a whole new software just because you change to a different broker.
