Market Capitalization Stock Screener
Build a market-cap stock screener in ChartsWatcher. Filter companies by equity size, then combine market capitalization with price, float and activity.
Understand the metric
What is MarketCap?
Market capitalization describes the market value of a company’s equity, commonly understood through share price and shares outstanding. ChartsWatcher provides a market-cap filter that is updated once a week. It helps define a company-size universe for screening, while the documented update cadence distinguishes it from a field that tracks every current price movement.
An illustrative example
MarketCap in practice
A hypothetical screen between $300 million and $2 billion would retain a company showing $900 million and exclude one showing $8 billion. Because ChartsWatcher updates this field weekly, a sharp price move during the week may not immediately change its market-cap classification.
Make it part of your workflow
A more deliberate stock screen.
Use market cap to group the companies in a ChartsWatcher research list before applying current price and volume conditions. Display shares outstanding or float when share structure matters, and keep the field’s weekly update schedule in mind when reviewing names near your chosen boundary.
ChartsWatcher lets you combine this filter with other criteria in a toplist and rank the results by the columns you care about. Keep the shortlist beside charts, stock news, and watchlists in your own layout.

How do I add MarketCap in ChartsWatcher?
Open or create a toplist and add MarketCap to its filter configuration. Choose the available options and the bounds that fit your screen. Combine it with other metrics to narrow the results. Filters can also refine which stocks qualify for an alert.
What should I check when interpreting this filter?
ChartsWatcher updates market cap once a week. Fast price changes or share-count events can leave the displayed value different from a fresh calculation.
From an idea to your own scan.
Use MarketCap with the other conditions that define your setup. Keep matching stocks, charts, and news together, with a configuration you can refine as you go.
