The following are some drawbacks of stock screeners.

1. Requires specific criteria: Almost all the stocks are present in a stock screener. As a result, it becomes overcrowded. Therefore, users should specify the criteria carefully for specific results. To reduce the number of results below 100, they might need to enter more than six unique search criteria. Many investors enter two or three criteria, which gives several search results. This makes it difficult to decide.

2. Only quantitative comparison: For choosing stocks, most stock screeners use quantitative parameters only. However, the qualitative factors should also be taken into account. These include issues with labour or company operations, corporate governance, consumer satisfaction, and ongoing litigations.

3. Inappropriate Comparisons: A market stock screener may not appear useful to some investors. For instance, a user may have entered a search parameter that does not depend on stock price. To get a result, the stock screener can attempt to compare stocks according to their prices.


Stock screeners are a valuable tool for investors. They simplify the process of selecting stocks that match their investment strategies. Individuals can filter stocks based on specific criteria.

Moreover, stock screeners have certain limitations. They require precise criteria to work. In addition, they only focus on the quantitative parameters.
