You can repeat this selection process on your own by using info available online for free, such as from The Motley Fool or Yahoo Finance, and/or by gleaning data from services that may be available at your local library, for example, Value Line. Much more (typically free) information is likely yours for the asking from your brokerage firm. When doing research, you might look, for instance, at companies that have high safety ranks or financial strength ratings, ones with debt to equity of 0.30 or below, and corporations with both five-year returns on equity of 10% or better and thirteen-week share price increases of 5% or more.
Once having chosen several good stock candidates, the next steps depend on what kind of investor you are. Most people do not have the time or inclination for frequent trading. If they attempt it, there may be a variety of adverse temptations and distractions, such as from all the flashy television programs, time and again warning of this or that catastrophe right around the corner for otherwise fine stocks or promoting the company-of-the-moment, i.e. till the next commercial break.
Thus for most folks the idea may be to discover a handful of excellent companies, buy shares in them, and essentially forget about them. It is hard to imagine that one will go far wrong in this approach simply buying when the market is way down and holding "forever" a basket of such beauties as Berkshire Hathaway (BRK/B), Coca-Cola (KO), The Walt Disney Co. (DIS), Boeing (BA), or Google (GOOG).
