Webull Penny Stock Screener: A Step-by-Step Tutorial for Investors
The Webull penny stock screener is a free, built-in filter tool inside the Webull desktop and mobile app that lets you isolate stocks trading under a defined price threshold and layer additional criteria on top. For investors who already use Webull as their brokerage, it is a convenient starting point for penny stock discovery. For value investors who need granular fundamental data, its limitations become apparent quickly. This tutorial walks you through the exact setup steps and shows you where the tool excels and where you will need to supplement it.
Key Takeaways
- The Webull penny stock screener is accessible from the desktop app under the "Screener" tab and from the mobile app under "Market."
- Webull lets you filter by price, volume, market cap, P/E ratio, and several technical indicators, but its fundamental depth is limited compared to dedicated screeners.
- You can set a maximum price of $5.00 to capture the penny stock universe, then layer filters for market cap, volume, and basic ratios.
- Webull does not offer operating cash flow filters, Piotroski F-score, or ROIC, which are the most useful fundamentals for distinguishing viable penny stocks from distressed ones.
- For investors who want both Webull execution and deeper fundamental screening, running an initial scan in Webull and verifying results in the ValueMarkers screener covers both bases.
- Webull is commission-free, which makes it cost-effective for small-position penny stock trading once you have identified a candidate through proper fundamental analysis.
What the Webull Screener Covers
Webull's screener database covers U.S. stocks listed on NYSE, NASDAQ, and AMEX. It does not cover OTC Bulletin Board or pink sheet stocks, which eliminates a large portion of the sub-$1 penny stock universe. This is actually a useful constraint for value investors: OTC names carry minimal reporting obligations, so filtering them out by default removes many of the names most likely to be fraudulent or have unreliable financial data.
Within the listed universe, Webull's penny stock filters include:
- Price range: Set maximum to $5.00 for standard penny stock screening
- Market capitalization: Minimum and maximum values available
- Average daily volume: Useful for eliminating illiquid names
- P/E ratio: Basic valuation filter
- Dividend yield: For income-focused penny stock searches
- 52-week price change: For identifying names that have declined significantly from highs
- Technical indicators: RSI, moving average cross signals, MACD
What Webull does not offer: operating cash flow, return on equity, debt-to-equity ratio, price-to-book ratio, ROIC, or any multi-factor quality composite like the VMCI Score we use at ValueMarkers.
Step-by-Step: Setting Up the Webull Penny Stock Screener on Desktop
Step 1: Open the Webull desktop application and log into your account. The screener is available to users without an account, but saved screens require a free Webull account.
Step 2: Click "Screener" in the top navigation bar. The default view shows the full U.S. stock universe without filters applied.
Step 3: In the filter panel on the left side, locate "Price." Click to expand and set the Maximum to 5.00. This establishes your penny stock universe. You should see the results count drop significantly in the results panel.
Step 4: Set a minimum Market Cap. We recommend $10 million as a floor. This removes shell companies and micro-cap names with fewer than a few hundred shareholders.
Step 5: Set Average Daily Volume minimum to 50,000 shares. Below this threshold, you face execution risk: the spread between bid and ask prices can consume 3-10% of your position value on entry alone.
Step 6: Set P/E ratio maximum to 30. This removes penny stocks where the market is still pricing in aggressive growth that the business has not yet demonstrated.
Step 7: Sort the results by Market Cap ascending to see the smallest qualifying names first, or by 52-week price change descending to see names that have recovered from recent lows.
Step 8: Click any name in the results to open its stock page. Webull's stock pages include a "Financials" tab that shows revenue, net income, and earnings per share trends for the past four quarters. Use this tab to verify that revenue is real and trending in a direction you can justify.
Step-by-Step: Setting Up the Webull Penny Stock Screener on Mobile
Step 1: Open the Webull mobile app and tap "Markets" at the bottom navigation.
Step 2: Scroll to find "Stock Screener" and tap it.
Step 3: Tap "Add Filter" and select "Price." Set the upper bound to 5.00.
Step 4: Add a filter for "Market Cap" and set the minimum to $10 million.
Step 5: Add a filter for "Volume" and set the minimum to 50,000.
Step 6: Tap "Show Results" to see your filtered list. The mobile interface shows fewer data columns than the desktop version, so tap individual names to see the financial summary.
The mobile experience is adequate for reviewing results, but the desktop version is significantly more useful for building and adjusting filter combinations.
Comparing Webull Screener Filters to What Value Investors Actually Need
| Filter | Available in Webull | Available in ValueMarkers Screener |
|---|---|---|
| Price under $5 | Yes | Yes |
| Market cap minimum | Yes | Yes |
| Volume minimum | Yes | Yes |
| P/E ratio | Yes (basic) | Yes (trailing and forward) |
| Price-to-book (P/B) | No | Yes |
| Return on equity (ROE) | No | Yes |
| Debt-to-equity | No | Yes |
| Operating cash flow | No | Yes |
| ROIC | No | Yes |
| Piotroski F-score | No | Yes |
| Revenue growth (1Y, 3Y) | No | Yes |
| Shares outstanding trend | No | Yes |
| Dividend yield | Yes | Yes |
| VMCI Score composite | No | Yes |
The gap matters because P/E alone is nearly useless for penny stocks. Many penny stocks have negative earnings, which makes P/E undefined. The filters that actually distinguish survivable penny stocks, like positive operating cash flow, P/B below 1.0, and debt-to-equity below 1.5, are not available in Webull's screener.
How to Use Webull and ValueMarkers Together
A two-step workflow captures the best of both platforms.
First, use Webull to generate an initial list. Apply the filters described in the step-by-step section above: price under $5, market cap above $10 million, volume above 50,000, P/E under 30. Export the results list or note the top 20-30 names.
Second, take that list to the ValueMarkers screener and search each name individually. For each name, check the price-to-book ratio, the operating cash flow trend over three years, the debt-to-equity ratio, and the ROE. Apply the same thresholds described in the full penny stock screener guide: P/B under 2.0, positive operating cash flow, debt-to-equity under 2.0, ROE positive for at least two of the past three years.
What survives both rounds of filtering is a short list worth spending real research time on.
Common Webull Screener Errors to Avoid
Error 1: Leaving the default sort by volume. Webull sorts results by daily volume by default. High-volume penny stocks are often experiencing promotion events or momentum trades. Sorting by value-relevant metrics (P/E, market cap) gives you a better starting list.
Error 2: Trusting the P/E filter to catch overvalued names. A penny stock with no earnings shows as N/A in P/E. Webull's filter may include or exclude N/A names depending on how it handles missing data. Always check whether your P/E maximum filter is actually removing unprofitable names or simply excluding the field from those names.
Error 3: Using the screener without checking the Financials tab. The screener gives you a list. The Financials tab on each stock's page gives you the revenue and earnings trend that tells you whether the business is actually functioning.
Error 4: Not verifying exchange listing. Webull covers NYSE, NASDAQ, and AMEX. If you are looking for OTC penny stocks specifically, Webull is not the tool for that. Confirm any OTC names through a dedicated OTC data source.

Frequently Asked Questions
what happens if the stock market crashes
When the stock market crashes, penny stocks lose value faster than large-cap benchmarks because they have no institutional buyer support. During the 2020 COVID crash, the Russell Microcap Index fell over 40% in five weeks while the S&P 500 fell roughly 34%. Penny stocks with no cash reserves and high debt levels are also more likely to go to zero during a crash because credit markets tighten and refinancing options disappear. Maintaining cash and keeping penny stock exposure below 10% of a portfolio provides a buffer.
what time does the stock market open
U.S. equity markets open at 9:30 a.m. Eastern Time, Monday through Friday. Webull offers pre-market trading starting at 4:00 a.m. Eastern and after-hours trading until 8:00 p.m. Eastern. For penny stocks specifically, pre-market and after-hours liquidity is extremely thin, and executing trades during those windows often means accepting a wide spread between the bid and ask price that immediately puts your position at a loss.
are stock markets closed today
U.S. markets close on nine federal holidays: New Year's Day, Martin Luther King Jr. Day, Presidents Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving, and Christmas. Webull's app displays a notice on the trading screen when markets are closed. You can also check the NYSE market calendar at nyse.com for the full schedule of closures each year.
what time does the stock market close
U.S. equity markets close at 4:00 p.m. Eastern Time on standard trading days. Webull's after-hours session runs until 8:00 p.m. Eastern. For penny stocks, the most liquid trading window is 9:30 a.m. to 11:30 a.m. Eastern, when institutional and retail volume overlaps. Trades executed in the final minutes of the session or in after-hours often see worse fill prices due to thinner order books.
when does the stock market open
The NYSE and NASDAQ open at 9:30 a.m. Eastern Time. Webull's pre-market session begins at 4:00 a.m. for eligible securities. Not all penny stocks are available for pre-market trading on Webull: the platform restricts pre-market trading to NASDAQ and NYSE-listed stocks, and some very low-volume names may have no pre-market liquidity at all regardless of platform availability.
why is the stock market down today
Markets fall for many reasons, including disappointing earnings reports from index heavyweights, Federal Reserve rate decisions, inflation data releases, geopolitical events, or broad de-risking by institutional investors. Penny stocks tend to fall harder than the broader market on down days because their investor base is predominantly retail, and retail investors are more likely to sell at the first sign of market stress. Webull's news feed and earnings calendar can help you understand what event is driving a given day's move.
