Insider buys, big funds, politicians, fundamentals, momentum & seasonality — 13 data layers across 17,000+ stocks fused into one A++–F score. See the whole picture, not fragments — decide on data, not gut feel.
Replaces 6 paid tools — with one score.
Register free. No card.
One grade A++ to F = a summary of 5 angles on a stock. Green = strong.
Illustrative interface sample with a fictional company — not a rating of any real stock.
No guesswork. A consistent analytical workflow: discover → analyze → compare → validate → monitor → document → learn. All in one tool.
The screener and 5-pillar score filter 17,000+ stocks. And you don’t have to rely on the score alone — 12+ data-event & monitoring categories (insiders & clusters, unusual options, squeeze, earnings beats, textbook patterns, confluence…) surface even more research candidates matching selected criteria, without manual hunting.
The A++–F composite and 5 pillars show how strong the story is — value, momentum, smart money, sentiment, catalysts. For each data category you also see its forward-measured track record — what actually worked, not just promises.
See what insiders, big funds (13F), Congress, off-exchange trading (FINRA) and options are doing — whether independent data layers align.
Historical price-context ranges, seasonal windows and market regime give you context on whether model conditions are becoming more active now — or still quiet. Descriptive, no guaranteed outcome, not a trade instruction.
Set your price bands and scenario thresholds with a Stop Alert (a notice only — it never auto-sells) and get pinged on moves.
The investment journal, performance view and Research Review Assistant show you what works and help you improve.
QMA then watches your positions and alerts you to a holding drop, negative news or over-concentration (rebalance). You decide — QMA only informs.
QMA 用多种方法（DCF、P/E、P/B、股息模型）计算内在价值，并给出一个清晰结论 —— 被低估、合理或被高估。你立刻就能看到是否合理，以及为什么。
Insider buys, big funds (13F), US politicians, off-exchange trading (FINRA) and options — QMA fuses them into one conviction. When data layers align, you see it instantly.
Ask in plain words — QMA summarizes a stock, explains moves and compares. Plain-language, even for total beginners. Descriptive, not a trading instruction.
Illustrative conversation with the fictional company ACME.
No jargon. Here's what you actually get — even if you're just starting out.
Paste your holdings and see a 0–100 score: diversification, quality, risk, correlation.
Part of the Starter plan.
See how the past would've played out — you pick the stock, we compute what $10k invested 10 years ago would be today (vs the index).
Pro: 20y of prices + 1y strategy replay.
No need to read a balance sheet. QMA re-scores 30,000+ stocks and ETFs every week and grades each from A++ to F — you instantly see what's worth a look.
Pro: 13 sub-scores, regime-aware weights.
Company insiders, US politicians and big funds leave tracks. QMA follows them and shows you in one place.
Pro: insider cluster + Congress + off-exchange trading (FINRA) + options + 13F, bidirectional.
Top Kompozit: a clearly described selection method among the top-rated large US companies. Live-tracking results will be published in the pilot only once there is enough data for a fair comparison with the index. An analytical simulation, not trading instructions.
Special configuration: large US firms (major exchanges, top-percentile Composite), monthly rebalance of the top 20 — not a raw Screener sort. Past ≠ future.
A journal sample: the shape of the screen for logging trades and a Czech tax summary. Your own records open in an account, not behind a login wall.
In an account: trade import (CSV) and a summary export to Excel and PDF.
Everything is explained plainly, with a tooltip on every technical term. Setup takes minutes.
Pro: switch to full mode anytime.
QMA 是一款分析与教育工具，并非持牌投资顾问。我们描述数据和策略做了什么 —— 决策由你来做。过往表现不保证未来结果。
Institutional-grade data — insiders, off-exchange trading (FINRA), 13F, options — decoded into clear analytical observations, in one place. Skip 50 browser tabs.
醒来就知道该看哪里——你最强的 3 个研究案例在每天 06:00 UTC 等着你，每个都附有逻辑依据、风险等级，以及解释它的隔夜新闻。它通过对整个 7,700 只股票的全域按全部 13 个因子评分而构建——一份在开盘前、基于最新每日数据准备好的精选清单。
See which executives buy shares of their own company with their own money. We read every SEC Form 4 filing, score each purchase, flag clusters of insiders buying together and weight by how fresh the filing is — so you can see which purchases stand out in the data. A description of public filings, not a recommendation.
追踪已申报的机构资金流。我们把五个公开数据源——FINRA 场外交易数据、SEC 内部人申报（Form 4）、国会议员交易（STOCK Act）、异常期权流以及 13F 报告（最多延迟 45 天发布）——合并为一个 0–100 的分数，用来描述已申报活动的活跃程度。场外成交量（FINRA）并不显示是谁交易、交易方向如何。这是对数据的描述，而非建议。
再也不必纳闷『这为什么在动？』。每天清晨，AI 雷达扫描市场数据——异常成交量、板块轮动和宏观变化——并用通俗语言解释隔夜发生了什么变化。
读懂每只股票的历史择时窗口。QMA 从 10+ 年价格历史中梳理出每只股票反复出现的日历窗口，仅标记那些经 t-test 判定为统计上显著的窗口（≈ p < 0.05，样本内）。这些是经回测的历史形态，而非预测——但它们能让你识别历史上曾显现优势的窗口，而不是凭直觉行事。
绝不错过评级变化的那一刻。一旦某只股票的 QMA 评级上调，或其 Smart Money 共振翻转为看涨，你便会收到推送和邮件——让你在变化仍然新鲜时看到它，而非几天后才发现。这就像有一支研究团队 24/7 盯着你的整个观察列表。
用日常语言向市场提问——『财报前呈现看涨特征的股票』——几秒钟就能得到真正的答案。该助手将实时网络搜索与你自己的 QMA 评分及机构数据融合在一起，一次查询就完成原本需要数小时人工筛选的工作。无需学会分析师的工具，也能像分析师一样做研究。
Track short-squeeze conditions: FINRA failure-to-deliver, the off-exchange short-volume ratio (FINRA), short interest and momentum in one score. Most screeners show short interest alone; QMA shows the full pressure picture.
大多数筛选器把你淹没在数百只股票里，剩下的全靠你猜。
QMA 按机构级优势对整个市场排序，只呈现那少数值得你花时间的股票。
一个字母评级让你一眼看清股票质量——A++ 到 F——你再也无需自己权衡十几项指标。在底层，每只股票都按由 13 个因子构成的 5 大超级支柱评分，涵盖价值、动量、Smart Money、情绪和催化剂——与机构交易席位权衡的维度相同，且完全透明，专业者可审查每一项输入。新手得到一个数字；进阶交易者得到整个引擎。
从 10+ 年历史中了解一只股票最佳与最差的日历窗口——经 t-test 标记、经回测、样本内（并非预测）
在投入一分钱之前无风险地压力测试任何想法——纸上交易与回测，不下真实订单

We score ETFs and look through to QMA-grade the stocks they hold.

Which executives are buying their own stock with their own money — and how much. Without an account you see a sample of the list, not a login form.
A no-commitment simulation: build a model dividend portfolio and see the payout calendar, yield-on-cost and reinvestment effect. Educational tool, not money management.
Portfolio risk & concentration analysis with alerts — all in one place.

Top Kompozit is a described selection method, not a result — live-tracking results will be published in the pilot only once there is enough data. Further research methods are tiered honestly: 📍 tracked (no demonstrated edge) / ⚠️ experimental. Analytical simulations for research, not trading instructions.
Not a mechanical rules-bot. It’s an autonomous, thinking AI agent.
A classic robot blindly follows fixed rules. QMA Brain instead reasons in plain language: it researches the whole platform itself — fundamentals, technicals, smart money, insiders, options, news, macro and market regime — forms its own view, and above all explains WHY. It keeps a memory across the platform and continuously scores how its own predictions turn out.
An internal research experiment. It works with virtual money (paper) — for research and education, NOT investment advice.
