What Fundamental Fields Do Scanners Typically Offer?
Common fields include market capitalization, shares float, sector and industry, earnings per share growth, revenue growth, price-to-earnings, price-to-sales, debt ratios, dividend yield, and next earnings date. Scanners may flag recent earnings surprises or estimate revisions. These filters help exclude microcaps you cannot trade safely or sectors outside your expertise. Fundamental scans rarely fire intraday signals alone—they produce candidate pools for technical timing or event-driven trades.
Earnings date filters are essential for avoiding accidental binary risk on unrelated strategies.
How Do Traders Combine Fundamental and Technical Scans?
Workflow one: fundamental screen weekly for liquid mid caps with positive earnings growth and reasonable valuation. Technical scan daily on that reduced list for breakouts or pullbacks. Workflow two: technical scan finds momentum leaders; fundamental check confirms no imminent earnings and adequate float. Workflow three: earnings surprise scan post-report, then technical scan for gap-and-go or pullback continuation. The fundamental layer answers whether the business context supports the trade; the technical layer answers when.
Keep a static fundamental whitelist updated weekly; run faster technical scans only on that subset intraday.
When Does Fundamental Scanning Matter Most?
Swing and position traders holding days to weeks care about earnings quality, debt, and sector tailwinds. Earnings-season strategies scan for report dates, whisper numbers, and historical post-earnings drift. Long-only investors screen for profitability and growth consistency. Day traders use lighter fundamental filters—float, market cap, earnings today yes/no—mainly for risk control. Match fundamental depth to hold period; scalping five-minute charts rarely needs P/E but always needs tradable float.
Exclude stocks reporting earnings today unless earnings are explicitly your strategy catalyst.
What Are Practical Fundamental Filter Starting Points?
Liquidity: market cap above five hundred million, average volume above five hundred thousand shares. Risk: float above ten million shares to reduce squeeze distortion. Growth swing template: positive year-over-year EPS growth, price above fifty-day MA. Value template: P/E below sector median with positive revenue trend. Event template: earnings within five days, average move above five percent. Adjust thresholds to your universe—small-cap specialists use different floors than large-cap momentum traders.
Document why each threshold exists so you can test removing it without guessing.
What Pitfalls Should You Avoid?
Chasing high growth at any valuation without technical structure. Ignoring debt and dilution on speculative names. Fundamental screens that update rarely while you trade intraday signals on stale membership. Confusing screen hits with due diligence—scanning is triage, not research. Use fundamental scans to respect risk and focus; confirm catalysts and chart setup before committing capital.
Pair every fundamental watchlist name with an earnings calendar entry and sector news check before sizing up.
