Screener — How to Sift Out the Strongest Stocks from Thousands
Imagine standing before a mountain of sand with a few grains of gold hidden inside. You could sift through it manually with a shovel for days — or you could use a sieve with precisely set holes, shake it a few times, and the gold will remain on top. The Screener in QMA is exactly this sieve. There are thousands of stocks on the U.S. market. No person can go through them manually. The Screener scans the entire market for you every day, scores companies based on five pillars of quality, and lets you filter them so that only the 10–30 names worth a closer look remain on your screen.
This article will guide you through every window, button, and column of the Screener. The goal is not for you to memorize names — the goal is for you to gain perspective: understand what each function does, how to combine them into a real edge, and how to integrate the Screener into the entire process from idea to portfolio position.

What the Screener is Actually For
The Screener does not solve the question of "which one stock to buy." It addresses a higher-level question: "from the entire market — where should I even look?"
Most beginners do the opposite. They hear a ticker somewhere (from a friend, on YouTube, in a headline), buy it, and only then look for reasons why it was a good idea. This is called confirmation bias and it's the most expensive habit in the market. The Screener forces you to go the other way around and much healthier:
First, I define what a strong opportunity looks like (quality company + good timing + interest from smart money), and only then do I choose among such candidates.
This is called systematic selection and it's exactly what professional funds do. The Screener gives you the same tool — just in a language that even a beginner can understand.
★ Insight: The Screener is a filter, not a crystal ball. No screener can predict tomorrow's price. What it can do is dramatically narrow the field — instead of thousands of possibilities, it gives you 20 statistically above-average candidates. Your chances of finding a good stock increase not because the screener "knows," but because it eliminated thousands of weak names that you would otherwise spend time on.

Anatomy of the Screen — Top to Bottom
The Screener has a logical structure: at the top, context (where the strength is in the market right now), in the middle, quick views and smart filters, and at the bottom, the table itself with candidates. Let's go through it step by step.
1. Sector Radar — Where the Wind is Blowing
At the very top, you see the Sector Radar: an overview of sectors (Technology, Healthcare, Energy, Finance…) sorted by current strength. It works like a weather forecast for the entire market.
The market does not move as one block. At one moment, semiconductors are leading, another time energy, another time banks. This shifting of money between sectors is called sector rotation. When you see Energy at the top and Real Estate at the bottom, it means capital is currently flowing into energy.
How to use it: Stocks from a currently strong sector have the wind at their back — even an average company in a strong sector often grows more than a great company in a weak one. Before you start filtering individual stocks, look at the radar and consider whether you want to search within the 2–3 strongest sectors.
★ Insight: "Go with the flow." Picking a great company in a dying sector is like rowing against the current — it can be done, but it takes much more effort. The radar shows you where the current is flowing.
2. Strategy by Horizon — Pre-set Views
Below the radar, you'll find a switch for views based on how long you want to hold the stock:
| View | For Whom | What it Roughly Filters |
|---|---|---|
| Default | Everyone | Balanced view, sorted by Composite score |
| Short-term | Active traders (days) | Momentum, proximity to breakout, higher turnover |
| Swing | Medium (weeks) | Strength of setup + technical patterns + timing |
| Investment | Long-term (months–years) | Quality, ROIC, FCF, valuation, growth |
| Popular Screens | Inspiration | Ready-made "recipes" (e.g., quality growth, value) |
Practical tip: Always start with the view that matches your actual horizon. The most common mistake beginners make is searching in the "Swing" view but then holding the position for half a year — the criteria for these two worlds are different, and you're mixing apples and oranges.
3. "Who's Buying Right Now?" — Tracking Smart Money
This is one of the most valuable parts of the Screener and where QMA does something that regular screeners can't. Here you'll find a set of chips (clickable tags):
- 🧑💼 Insiders Buying — directors and managers of the company buying their own shares
- 🏛️ Senators / Congress — U.S. lawmakers reporting purchases (they are required to disclose them)
- 🏦 Big Funds (13F) — institutional investors accumulating positions
- ⚡ All at Once (confluence) — multiple signals converged on the same stock simultaneously
Why does this make sense? These players have something you don't: an insider knows their company from the inside, a fund has an analytical team worth millions, a congressman sees what's coming in legislation. You're not copying them blindly — you're just observing where "smart" capital is flowing and using it as one of the indicators.
★ Insight: What 🏦 13F Means. Big funds must report their positions quarterly in Form 13F. When the Screener tags a stock with 🏦, it means that multiple large institutions are accumulating a stake in it. It's not a directive — it's information like "big players see value here." Note: 13F data is delayed (up to 45 days), so take it as trend confirmation, not a fresh tip.
Confluence is King. One signal can be a coincidence. But when on one stock an insider buys + a fund accumulates + a congressman adds in the same period, it's much stronger. The "All at Once" chip finds these rare convergences for you with one click.
4. Strength of Setup — 💎 ELITE and Presets
Next to smart money, you'll find the Strength of Setup filter and quick presets:
- 💎 ELITE — backtested combination of factors that historically worked best
- Ready to Trade — stocks with a complete, fresh setup
- Growth — emphasis on revenue and profit acceleration
- Advanced Filters — manual fine-tuning of everything else
🚨 CORRECTION NOTE (31 July 2026). Specific performance figures (alpha, win rate, sample
size) are being withdrawn from QMA's public surfaces — which is why you will not find them in
this text. They were computed through a historical scores table whose older part was derived from
later prices, and since 31 July 2026 a stricter significance threshold applies, derived from every
trial ever run. The figures are not replaced by lower ones — the input data was never valid as
of the day in question. This text describes what the tool does, not what result it produced.
Only forward tracking since 18 February 2026 is probative.
★ Insight: The ELITE filter works like a bouncer at a luxury club. It only lets in those who meet all the conditions at once. When you see 💎 on a stock, it means "more things came together here at once" — and it's the convergence, not one standout figure, that tends to be the most reliable.
5. Classic Filters — Your Manual Control
Below the presets, you have a full palette of manual filters:
| Filter | What It Does | Example Use |
|---|---|---|
| Region | Market (US, European…) | Focus only on U.S. stocks |
| Index | Membership (S&P 500, Nasdaq 100…) | Only large, liquid companies from the S&P 500 |
| Sector | Industry | After looking at the radar, choose a strong sector |
| Size (MCap) | Market Capitalization | Avoid risky micro-cap companies |
| Min. Score | Lower Composite Limit | Show only the top-rated companies |
| Pattern (Grade) | Grade A++ to F | Only stocks with grade A and better |
6. Switch Stocks / ETF / All
At the top of the table, you switch between:
- Stocks — individual stocks
- ETF — exchange-traded funds (baskets of stocks)
- All — both
Beginners often appreciate the ETF mode: an ETF is less risky than a single stock (the risk is spread across dozens of companies). For ETFs, QMA shows clear data rather than a score (momentum, trend, relative strength).

How to Read the Table — Composite Score and Grades
The table is the heart of the Screener. It looks like an airplane cockpit at first glance, but once you understand a few key columns, the rest will fill in as needed.
Composite Score (0–100) — One Number, Five Pillars
Composite Score is the overall rating of a company on a scale of 0–100. It is created by combining five super-pillars, each evaluating a different dimension of the company:
| Pillar | Weight | What It Measures | In Layman's Terms |
|---|---|---|---|
| VALUE | 25% | Value and quality of earnings | Is the company cheap relative to what it earns? |
| MOMENTUM | 20% | Strength of trend | Is the price rising and has momentum? |
| SMART MONEY | 25% | Activity of institutions/insiders | Are smart money accumulating it? |
| SENTIMENT | 10% | Mood and news | What does the environment say about the company? |
| CATALYST | 20% | Upcoming triggers | Is something approaching that will move the price? |
★ Insight: Why Five Pillars and Not One? Because a company can be great in one and terrible in another. A stock can be extremely cheap (VALUE 90), but falling like a stone (MOMENTUM 20) — this is known as a "value trap." The Composite averages these contradictions with weights, so you don't get carried away by one tempting figure and overlook warnings in another pillar. Whenever a high Composite catches your eye, click on the detail and see WHICH pillars are driving it.
Important: QMA never falsifies data. If information is missing for a pillar, it shows "—" instead of an invented fifty. So if you see a dash in a pillar, it doesn't mean "average" — it means "we don't know this," and you should be more cautious.
Grade (Grade) A++ to F
Next to the number is a letter grade — the same logic as in school. A++ is the top, F is a failure. The grade is a quick visual shortcut: when scrolling through a list, the eye catches "A++" faster than "87." The number and grade say the same thing, just in different languages.
Other Columns — Glossary
You can customize the table (turn columns on/off). Here's a translation of the most important ones:
| Column | Meaning | How to Read |
|---|---|---|
| Timing | Position in price range (ICT) | "Discount" = cheap zone, "Premium" = expensive zone |
| Risk | Level of risk | Lower = smoother ride |
| Target | Analysts' target price | How much upside Wall Street sees |
| Seasonal | Seasonal pattern | Is this stock typically strong in this period? |
| STRATEGY | Membership in QMA strategies | Is the stock part of a verified strategy? |
| Conv | Conviction | How strong is the overall signal conviction |
| CONF | Confluence (signal convergence) | How many signals converged |
| MCap | Market Capitalization | Size of the company |
| 7D / 3M / YTD / 1Y / 5Y | Returns for the period | Short and long performance |
| P/E, FWD P/E | Price / earnings (including forward) | Expensiveness relative to earnings |
| DivY | Dividend yield | How much it pays in dividends |
| Growth | Revenue/profit growth | How fast it's growing |
| ROIC | Return on invested capital | How efficiently it earns |
| FCF % | Free cash flow yield | How much real cash it generates |
| ND/E | Net debt / equity | How indebted it is |
| PEG | P/E relative to growth | Cheap relative to its growth? |
| vs HI | Distance from yearly high | Close to the top, or far? |
| Earn | Earnings date | When it reports (beware of volatility) |
| An# | Number of analysts | How many are covering it (coverage) |
| Beta | Sensitivity to the market | >1 = wilder than the market |
| SI % | Short interest | How much is bet against it |
| Volx | Multiple of usual volume | Unusual activity? |
| Insider $ | Volume of insider purchases | How much insiders invested |
| 🏦 13F | Badge — funds accumulating | Institutional interest |

How to Combine Filters into a Real Edge
Here's the core of the whole art. One filter is weak. Combining filters creates an edge — because each additional condition cuts off more weak names and increases the probability that what remains is truly strong.
Think of it as stacking conditions with a logical "AND":
The company must be quality AND have good timing AND smart money must be accumulating it AND be in a strong sector.
Each "and" narrows the selection. From thousands of stocks, it suddenly becomes 12.
★ Insight: The Power of Intersection. When one filter lets 10% of the market through and another independent filter also 10%, their intersection is roughly 1%. Four reasonable filters will turn thousands of stocks into a handful — and that's exactly the handful worth spending time on. The key word is "reasonable": filters must be independent and meaningful, not five variations on the same theme.
Three Sample Combinations
A) Quality Long-term Investment
View: Investment
Min. Score: ≥ 75 · Grade: A and better
ROIC: high · FCF %: positive · ND/E: low
Sector: one of the top 3 on the radar
→ You'll get quality, profitable, non-overleveraged companies in a strong sector.
B) Swing with Smart Money Confirmation
View: Swing
Strength of Setup: 💎 ELITE
Chip: ⚡ All at Once (confluence)
Timing: discount zone · vs HI: still room to go up
→ A narrow list of stocks with a verified setup where signals converged and the price isn't overheated.
C) Insider Trail in Large Companies
Index: S&P 500
Chip: 🧑💼 Insiders Buying
Insider $: high volume
Min. Score: ≥ 65
→ Large, liquid companies where managers are betting their own money.

Practical Stock Selection Process — Step by Step
Let's unify it into a repeatable ritual you can use every time:
- Look at the radar. Which 2–3 sectors are at the top? Search there.
- Choose the horizon. Investing for months? → Investment view. Trading for weeks? → Swing.
- Apply a coarse sieve. Min. Score (e.g., ≥ 70) + Grade A+ and better. This drops 80% of the list.
- Add an edge filter. 💎 ELITE or smart money chip — depending on what you trust more.
- Sort by priority. Composite score, or CONF (confluence), or yield — according to strategy.
- Go through the top 5–10 and click on details. For each, ask: WHICH pillars are driving it? Is there a hidden weakness (e.g., Earn = earnings are approaching and volatility threatens)?
- Check timing and risk. Is it in the discount zone, or overheated at the maximum? What's the Risk and Beta?
- Save favorites to the Watchlist. Don't rush. Watch them for a few days.

5 Tips for Long-term Success with the Screener
Tip 1 — Start with a wide sieve, then tighten. Don't start with ten strict filters at once (you'll end up with zero stocks and be frustrated). Apply 2–3 coarse filters, see how many are left, and gradually add conditions until you have a manageable list of 10–20 names.
Tip 2 — Confluence > one standout figure. A stock with five good figures and no excellent one is often a better bet than a stock with one dazzling number and four weak ones. Watch the CONF column and the "All at Once" chip — convergence is more reliable than a lone star.
Tip 3 — Respect timing. A great company bought in the "premium" zone (just below the yearly high, overheated) can stagnate for years. The same company in the "discount" zone offers a much better risk-reward ratio. The Timing and vs HI columns are your friends.
Tip 4 — Keep one screen and repeat it. Find a combination of filters that suits your nature, save it (or remember the recipe), and use it regularly. Consistency beats random searching. Professionals don't improvise every day — they have a process.
Tip 5 — Beware of data traps. Micro-cap companies (very low MCap) and stocks with low coverage (small An#) tend to have volatile, less reliable data. Extremely low P/E or gigantic dividend yields are often warnings, not opportunities. Filter for reasonable size and liquidity, so you don't drown in noise.

How the Screener Fits into the Entire Workflow
The Screener is not an island. It is the first step in a chain that takes you from idea to position:
SCREENER → WATCHLIST → STOCK DETAIL → PORTFOLIO → STRATEGY
(filter) (watch) (explore) (hold+monitor) (integrate into plan)
- Screener finds candidates. Buttons next to each row allow you to save the stock directly to the Watchlist or add it to the portfolio.
- Watchlist is your "waiting room." Here you put favorites and observe them for a few days before deciding — you don't rush.
- Stock Detail is a deep dive. You click on a candidate and see the breakdown of all five pillars, chart, fundamentals, insider activity, technical zones. This is where decisions are made.
- Portfolio holds your actual positions — it tracks profit/loss, risk, tax impacts, alerts.
- Strategy is the framework. The STRATEGY column in the Screener already shows whether a stock is part of any verified QMA strategies — the connection is thus bidirectional.
★ Insight: The Watchlist is your buffer against impulse. The most expensive trades are the impulsive ones. If you establish a rule "I won't buy anything until it's been in the Watchlist for a week," you'll filter out most emotional decisions. The Screener gives you candidates quickly — but the pause between finding and acting is often the most valuable thing you can afford.

Common Mistakes to Avoid
| Mistake | Why It's Bad | What to Do Instead |
|---|---|---|
| Chasing One Number | High Composite can hide a weak pillar | Always click on details and look at the breakdown |
| Too Many Filters at Once | Ends up with zero stocks, frustration | Start coarse, tighten gradually |
| Ignoring the Horizon | Swing criteria ≠ investment criteria | Choose a view based on the real holding period |
| Overlooking Earn (Earnings) | Earnings = high volatility | Check the date, consider the risk |
| Micro-caps Without Coverage | Unreliable data, low liquidity | Filter for reasonable MCap and An# |
| Blindly Copying 13F | Data is delayed up to 45 days | Take as trend confirmation, not a fresh tip |
| Mistaking "—" for Average | Dash = missing data, not neutral | Be more cautious where data is missing |
| Action Without Pause | Impulse is the enemy of returns | Let the candidate sit in the Watchlist |
Summary
The Screener is the most powerful tool for the search phase. It turns an unmanageable ocean of thousands of stocks into a clear list of a few strong candidates. The key to its profitable use lies in understanding three things:
- Read Composite Score through Five Pillars — one number is a distillate, but decisions are made in the breakdown into pillars.
- Combine Filters into an Edge — the strength is in the intersection, not in one criterion. Confluence (convergence) beats lone stars.
- Integrate the Screener into the Chain — Screener → Watchlist → Detail → Portfolio → Strategy. The Screener suggests, you decide with perspective.
