Technologies are developing fast nowadays, with lots of new stock market analysis apps and websites appearing every day, starting from trading and stock analysis solutions and ending with investment advisory apps. It is easy to get lost in this app universe and end up using something not well tailored for your investment needs. In this article, I want to show some of the great stock research websites and stock analysis apps that will help you find the best undervalued stocks to buy now. After reading this article, you will be able to choose apps/websites tailored to your research needs and find truly amazing equities for your investment portfolio.
When it comes to stock research websites and apps, we can divide them into two main categories. Stock research websites and web apps without trading capabilities, and the second category is websites and apps with such capabilities.
First, let’s start with websites and apps that offer research capabilities without the possibility to trade shares.
Stock screener and portfolio builder.
Diversset.com is built by a former institutional trader and investment analyst. Diversset helps traders find stocks and ETFs tailored to the trader’s risk appetite and return expectations and builds an efficient investment portfolio with minimized risk and maximized return. Let’s consider in more detail how this web-based app works.
To use the app, go to the Diversset, portfolio builder website. On the main screen that appeared press the Try the app button.
Register/Login In the newly opened window. After that, the screener tab opens. Unlike many stock screeners that are available on the market, Diversset is not showing you complicated screening options and confusing filters. You only have to answer two simple questions: your investor type, risk averse, risk seeking, or moderate (something between risk averse and risk seeking) and your portfolio’s expected return. Then, press the Show the result button as shown in the picture below.
After that, Diversset finds you stocks and ETFs tailored to your risk appetite. Diversset applies filters and financial ratios based on your preferences (questions that you answered at the first stage) and shows you the list of stocks and ETFs that you can choose from. The list shows details like company name, stock ticker, market capitalization, beta, and issuer country. You can manually pick 10 stocks and ETFs from the list and press the Portfolio builder button, and Diversset will build your efficient investment portfolio, from your chosen stocks, or you can simply press the Portfolio builder button without manually choosing stocks. If you choose the second option, Diversset will build your efficient portfolio from 10 most liquid stocks from the filtered list.
After pressing the button, Diversset starts making the magic. First, it uses the Markowitz model to build an efficient investment portfolio (allocating stock and ETF weights in such a way as to minimize portfolio’s loss, given your indicated return). The second part of the magic is an AI model that tries to maximize portfolio’s expected return. Two parts of the magic formula work in tandem, building scenarios of 10 thousand different investment portfolios, allocating asset weights in different combinations to get portfolio’s maximum return and minimum loss. Then Diversset chooses the most efficient portfolio and tells you what should be your optimal asset allocation to get minimum possible loss and maximum possible return. All these calculations are undertaken within a few seconds. You don’t have to make complicated portfolio building calculations and manually apply the Markowitz model. All these magic and complex calculations are done by Diversset in seconds.
At the last stage of the process, Diversset shows the efficient portfolio with assets allocated in such a way as to minimize the portfolio’s loss and maximize its expected return. In the below example, Diversset says that if you allocate assets in a way as shown in the picture, you get a 43% return with only 1.29% expected yearly loss. Sometimes Diversset says that no efficient portfolio with your indicated return was found; in this case, Diversset tries to show you the maximum possible return under the suggested asset allocation. In the example below, the return suggested by Diversset (43%) is much higher than our initially indicated return (13%).
But please remember that you should regularly (monthly, quarterly) re do your calculations and start the process again because some assets become more volatile, and portfolio composition and allocation may also change. Also, don’t forget to undertake your individual research on selected stocks before you undertake your final trading decision and consult with your investment advisor to have a wider investment view and manage your risk better.
Stock screener for advanced users.
If you still want to apply complicated financial ratios and know exactly how to find the best stocks to buy right now, using financial ratios, you can try using the Finviz stock screener.
Go to the finviz.com website, choose the Screener tab to access filters, and apply financial ratios filters to find the best stocks to buy now. You can see the example on how to apply financial ratios (the picture below). I would not recommend you putting more than 5 filters at the same time because you can end up having a very short list of stocks and may miss some really good trade ideas. To learn more about filtering options, you can read my article on Cheap Stocks To Buy Now where I explain what are some filtering options for finding fundamentally strong, undervalued (cheap) shares.
After applying filters, you can see the list of stocks with different fields like sector, industry, market cap, ratios, and price change. You can analyze stocks further, rank them based on ratios, and see the stock charts by pressing the TA tab at the bottom of the filters, as shown in the below picture.
Please keep in mind that this website is more for the initial stock selection (screening) process. Don’t base your trading decisions only on the results from the Finviz website. Once you filter stocks and have the list of equities filtered with the help of Finviz, it’s time to make further research to understand if you are holding truly value shares with strong fundamentals, and as with the previous case, also would be a good option to consult with investment professionals before undertaking the final trade decision.
Stock research websites for developers and investment professionals.
If you are an experienced developer, investment analyst, or trader and want to hold a pulse on market moves and trends and have customized stock research tools and analysis options, you can use the Financial Modeling Prep (FMP) website. FMP provides useful endpoints that will help you analyze stocks, build valuable financial models for your research needs, and create your own stock analysis websites and apps that will automate your research process.
Some of the example use cases of the Financial Modeling Prep endpoints can be found on my GitHub page, where I share simple, free apps for stock traders/investors. I made those apps using the Financial Modeling Prep endpoints. If you are a developer or investment analyst, you can clone my apps (instructions are provided in my GitHub), and if you are a beginner analyst or developer, you can examine my code and learn to use FMP API endpoints for building your custom stock research and analysis websites and apps tailored to your research needs. If you are interested in building your customized stock analysis solutions and building your own financial models, don't forget to obtain your custom API key with FMP before you begin. You need this key to use FMP's API endpoints.
Best stock research websites, simple solutions for stock investors and traders.
Now let’s talk about one very simple iOS app for equity (stock) investors and traders. This app provides mid-term and intraday trade recommendations based on both fundamental and technical analysis. Ideal for mid-term investors who want to understand if it is worth buying the stock from their short list (wish list) and also for intraday traders (short-term traders) who want to get fast trading signals and trade ideas. The app provides valuable stock entry and exit points based on the Japanese candlestick patterns analysis for intraday traders and EPS, social sentiment, stock target price, Piotroski score, dividend yield analysis for mid-term investors. To learn more about how to use the app for mid-term trades, you can read my article on Best Undervalued Stocks To Buy Now. For intraday traders (short-term traders), read the How To Day Trade For a Living article to learn how to use the app in the best possible way to get great entry and exit moments and know when is the best time to trade your chosen stock.
Now let’s start with stock research websites and web apps with trading capabilities.
They can be useful for undertaking in-depth stock research and trading shares.
Analyze stocks like a pro and buy great shares instantly.
The first stock research/trading website is Interactive Brokers. IB is a trading workstation (IBRK TWS) that can be used both using a web app/website and a side-alone app that can be downloaded on your computer. IBKR TWS has a stock screener, stock analysis, and trading functionality. You can have everything you need in a single app, no need for side apps, but some traders and investment analysts are saying that IBKR TWS is too complicated for them as there are too many options, screener filters, trading algorithms, and analysis data, and it can be stressful for a beginner or even intermediary traders to understand all those things.
If you want to master the IBKR TWS, you can start with stock fundamental analysis and understand how to find great shares using the trading workstation. For that, you can read my article on Fundamental Analysis in IB TWS, where I explain how to find great stocks fast and efficiently using the trade terminal.
If you are interested in trading stocks using the IB TWS and apply popular trading algos to lower your trading costs and get the best and fast execution, you can read my article on How to Lower Your Trading Costs.
TradeStation: flexibility and depth, all in one solution for traders.
TradeStation is a powerful platform that combines solid research tools with trading features, and it’s perfect for traders and investment analysts who want flexibility and depth. TradeStation is an online brokerage platform that’s been around for a while and is well-liked by active traders. It offers two main ways to use it: a web-based version you can access through your browser and a downloadable desktop app that gives you more control and features. Like Interactive Brokers’ Trader Workstation, it’s built for people who take trading seriously, whether you’re buying and selling stocks every day or digging deep into research to find the next big investment.
Advantages for investment analysts and traders:
Charts and Technical Analysis: Traders love charts, right? TradeStation has awesome charting tools with tons of indicators—like moving averages or RSI—that help you spot trends and decide when to buy or sell. You can customize everything to fit your style, whether you’re watching stocks, options, or even futures.
Fast Trading: The platform lets you place trades super quickly. You can set up hotkeys (just like Trader Workstation) to execute orders with one click, which is great for day traders who need speed. The desktop app is especially good for this because it’s built for power users.
Real-Time Data: You get live market data, so you’re always seeing what’s happening right now. This is key for traders who need to jump on opportunities the second they show up.
Deep Research Tools: TradeStation gives you access to a ton of data, like historical prices, earnings reports, and market news. Analysts can use this to study how a stock has performed over time and figure out if it’s worth investing in.
Screeners: Want to find stocks that match certain rules, like “growing fast with a low price”? TradeStation’s stock screener lets you filter through thousands of stocks based on things like price, volume, or financial ratios. It’s a quick way to narrow down your options.
Backtesting: Analysts love testing ideas. With TradeStation, you can take a strategy—like “buy stocks with high dividends”—and see how it would’ve worked in the past. This helps you figure out if your plan is solid before risking real money.
I've highlighted some of the best options for traders and investment analysts who want to get useful and accurate apps that will help traders on their investment journey. If you want to get valuable trade recommendations, you can use the Stocks 2 Buy iOS app. For finding great shares tailored to your risk appetite and building an efficient investment portfolio, use the Diversset web-based app. For manually applying filters based on financial ratios, use the Finviz web app. If you want to get financial data and build your custom apps, use the FMP data points. And for trading and analysis, use trading terminals that I highlighted. But please do your own research before buying shares and consult with your investment professional to better reflect your risk appetite. I hope you like the article. Please share it to help me spread the knowledge. Thanks.
