When you’re looking for specific companies, operators could be considered the bones of the search party. What are you looking for? Where are you looking? What do you want to find? Keep reading to hear exactly how they function.

## Further Explanation of Operators

Operators are the symbols or keywords that state what will happen to a property (a piece of data). Think of an operator as a verb. If a property is a piece of information about a company, the operator will say what the piece of information is doing.

For example, if you want to evaluate companies with a high P/E, you use the symbol ( > ) to determine the answer. If you want companies with a P/E greater than 25, then the formula looks like this,

P/E > 25

and the ( > ) is the operator in this formula.

Note that P/E is a financial metric, 25 is the constant, and ( > ) is the operator. The operator in this formula says the P/E is greater than 25, acting as the verb in the formula.

## Why You Want to Make Your Own Screener

At this point, you might be wondering why you would ever want to make your own stock screener, and we’ve got the answers.

1. Empowered Opportunities: – When you create your own stock screener, you approach it from your personal/professional understanding, which means you could uncover opportunities that others overlook. If you’re aware of valuable criteria, then you’re capable of incorporating that into your screeners.
2. Personalized Approach: – Creating your own screener is a personalized approach that fits your opinions and merits, not anybody else’s. You get to input the information and criteria you want, ultimately unleashing your understanding onto the market (watch out).
3. Quantitative Investments: You don’t want some regular Joe telling you what to invest in. You want to backtest your ideas on years of data and make decisions based on actual success, not opinions.

## Different Types of Operators

Now that you’re pumped for creating your own stock screener, here are the different types of operators to consider. It would be too simple to think there’s just one kind of operator when there are really four! Here they are:

• Mathematical: – You’ve got your classic mathematical operators, (*), (+), (-), (/), etc.
• True/False: – Some operators evaluate conditions, like (>), (<), etc.
• Time Definers: – Picking stocks based on a date or a certain amount of days, weeks, quarters, years, etc.
• Conjunctions: – Just like in English class, “if,” “or,” “and,” etc.

## Equities Lab Operators

Equities Lab has an organization system for operators to make it work for you! Here’s how our operators work:

• Across Operators: – Analyze data fields or terms across any set of stocks. Ex. finding the P/E of the top 50% in an industry.
• Within Operators: – Specifying the number of trading days and expectations for closing results.
• Since Operators: – Evaluate what specific dates you want to evaluate.
• Normal Operators: – Basic operators such as minus (-), plus (+), multiply (*), etc. to execute a range of conditions.

With these operators organized in such a way, think of it as another language for programming to create the criteria you want in a stock screener. If you have a screener with everything fixed to a pre-defined formula, you can easily create richer and more precise backtests with Equihacks. Not only do you have these basic operators, but 104 options to enhance your experience.
