When we look at possible investment opportunities, we tend to be relatively optimistic and bullish. After all, not only is the market rising, but when we read company news releases, presentations, and annual reports, management is always bullish. What are they going to say otherwise, ‘Sell our stock?’ But this is really a lousy approach. There are thousands of stocks out there trading all over the world every single day, and you are going to construct a portfolio of 10 — maybe 15.
It follows that as a stock picker, you need to be more selective than a Yale admissions officer. But how do you eliminate stocks from consideration? After all nobody has time to analyze the various public documents and talk to the managements and corporate relations personnel from every single company. Therefore, you need to develop strategies for screening out stocks so that you can focus your energies on a few companies that are worth considering. Here are a few strategies to consider.
1. Using Computerized Stock Screeners
This can be a good first step. Many brokers allow you to put in certain inputs such as market capitalization, price-to-earnings multiple, growth rate, dividend yield, profit margin, and so forth. The program scans through each stock and spits out the few that meet your criteria. This is a great way to reduce your list from thousands to a few hundred or even a few dozen if your criteria are selective enough.
The issue is that stock screeners are perfunctory mechanisms and they may miss something. For instance, if you screen for companies with price-to-earnings multiples that are lower than 15 and a company misses the cut because it had a one-time tax-related expense that lowered its reported earnings, then you could be missing out on a great opportunity. You could also find that the opposite happens: you get a list containing several companies with one time earnings gains and thus you have wasted your time.
One way around this is to only filter things that aren’t easily manipulated by these outside events. For instance, filter for revenue growth; one time revenue items are less likely to impact revenue growth. Generally, these are useful tools, but you need to be careful.
