My First Stock Screener

Introducing a simple stock screener

You should have the system up and running. There are several paths create a basic screener. On the Welcome to Equities Lab home page you can click the first entry “Find Stocks” and then select the third choice “Create your own algorithm.” Another choice is to click the sideways-facing top-left-most tab “Explorer” and then click “Create New Stock Screener.” Either way you are presented with a “New Stock Screener”.

The empty box with the pulsing cursor is waiting for you to type something. Let’s look for stocks that meet two tests: a PE that is less than 10 and a Market Capitalization that is greater than 70 billion dollars. This may not be the most interesting set of conditions to look for, but we will be dealing with facts we know something about. When we run it we will recognize the companies selected.

Before we are through with entering these two tests you will see there are several ways to get the same results. A preferred way is to enter an “operator” first. This will explode the single blank box into several boxes depending on which operator you enter. Since the first test is to find a PE less than 10, the operator is “<”. Enter that and press “Return.” Two new boxes appear creating a test waiting for parameters.

Type capital PE in the left box and 10 in the right box. Then click the blue GO button on the top line. You will see over 1,000 stocks selected in the bottom panel.

We want the second test to find companies with a market cap that is greater than 70 billion dollars. Click the green “+” button to add another test. You will see another empty box with the cursor waiting for your entry. This time enter a “>” operator. See two new boxes.

 

 

Let’s explore how Equities Lab prompts you. We want Market Capitalization in the left box, but that is a lot to type. Also, the name for that in Equities Lab is “Market_Cap” which you are welcome to type out in full, but that’s not necessary.

Each stock has over 1,400 of fields of information. We call each field a “Property.” You use these properties—you cannot change them. Properties are given mnemonic shorthand names that start with capital letters and contain underscores to subdivide and breakout a root property by time, by rank or other ways. Words that start with lower case letters cover everything else: things like operators, variables, tabs and formulas.

Armed with this new knowledge, type a capital “M” in the box to see what happens. You are prompted with four property names. As it turns out, the one you want is highlighted. Simply press return and the entry is correctly made. Two key strokes—no real typing skills needed!
