6 Stock Scanners That Can Help You Become A Better Investor

In the last decade, there has been an influx of retail stock market investors. The emergence of discount brokerage platforms such as Robinhood as well as access to tools such as stock scanners has made it easier for the retail investor to buy and sell stocks.

A stock scanner is basically a platform where investors can identify stocks and ETFs (exchange-traded funds) based on their investment criteria and strategy. There is a good chance that a well-established brokerage house will have a stock scanner that will be provided to users. However, there are several independent platforms that provide a subscription-based stock screening service to investors.

Here we take a look at some of these stock scanners that are available to investors.


The first stock scanner on this list is StocksToTrade. It has built-in proprietary algorithms and scanners that will help the user unlock real-time trading opportunities. Built by day traders and swing traders, STT is designed to be efficient with a focus on speed and an easy to use interface.

ORACLE analyzes several past winners and based on this back-tested data it will show you similar favorable conditions that the user can view and take a trading decision given the information. 

StockToTrade’s platform is available for $7 for a 14-day trial period. It is then priced at $179.95/month or $1899.50/year. 


One of the newest players in this space, Ziggma is a next-generation investment management platform. Its multi-asset screener allows the user to choose between equities, ETFs, and bonds. Ziggma not only provides you access to stocks in the U.S. markets, but its stock scanner also has details about various other equity markets such as China, Europe, Australia, and Southeast Asia.

Its stock screener has a variety of options where you can first filter companies based on the exchange, sector, industry as well as the country they trade in. You can then filter stocks based on metrics such as market cap, dividend yield, analyst recommendations, average volume as well as target prices.

For example, you have the option to look at tech stocks part of the S&P 500 with a trading volume of over 1 million shares that are trading at a discount of 30% to analyst estimates. Finviz’s free platform is quite powerful and it also provides access to more sophisticated tools via a subscription.

The final takeaway

A dynamic and easy-to-use stock scanner should accelerate investment decisions for retail investors. While some of these platforms are better for fundamental analysis they might not be the best option for technical traders.

You should know that every scanner is dependent on user inputs which will help you filter stocks and make an investment or trading decision quickly.
