Not all of us have the same preferences when it comes to selecting actions. And that is why we are going to talk about Stock Screeners, also called Stock Screeners. One of the most powerful tools that allow you not to wander through the great ocean of the world of actions. And, who has not found themselves in the situation of not knowing or cannot think about where to invest? Especially in times of economic uncertainty, or when it is not known which company can be better in a sector.
Many millionaires have made their fortune by filtering and being very selective a la hora de seleccionar las acciones de una compañía. Fundamentalmente por no dejarse llevar por corazonadas, y tener criterios objetivos a su disposición. Debido a que no hay nada más target que la parte numérica en las inversiones. Si como inversor además te preocupa asegurarte de hallar esa compañía que cumpla con todos los criterios que consideras indispensables, entonces este post es de tu interés.
What is a stock appraiser?

The filters de acciones son las herramientas que los inversores pueden usar para seleccionar acciones específicas. entre los cientos que se pueden hallar. Todo ello, en base a los criterios y selecciones que los usuarios (inversores) dan mayor relevance. Dependiendo de las funcionalidades o plataformas que los hayan creado, los stock screeners se pueden hallar en la Web desde versiones gratuitas más fáciles hasta algunas de pago (regularmente algo más elaboradas).
Among the most common preferences or selections, we can find different filters algunos de los cuales definen un PER (Price to Earning Ratio) que hemos indicado, el volumen de capitalización de mercado, la región en la que preferimos que cotice la compañía, el volumen promedio negociado, el sector entre el que se prefiere buscar, otros, varios ratios, etc. Algunas de estas plataformas y software posibilitan a los usuarios realizar una pantalla usando indicadores técnicos. Algunos tan habituales como el RSI (Relative Strength Index) o medias móviles a 50, 100 o 200 días, según los criterios que la persona siempre haya escogido anteriormente.

The main advantage of Stock Screeners, beyond allowing us to filter and go directly to the actions that interest us, is the optimization of personal time. In the past, many investors had to read the extensive guides (hundreds of pages) that were published annually presenting the financial statements of companies. Today would be enough for us a short time to go directly to those actions that meet the criteria we are looking for. And if it is a question of shortening the time, let's see some of the Stock Market Screeners that we can find on the net.
