Brain47Brain47 scores every stock.
Then runs one strategy, live and in public.
You watch. You understand.
Brain47's proprietary quant model scores every stock 0–100 across five factor categories — then runs one disciplined, systematic strategy: a factor-tilted book of around thirty names, rebalanced monthly, live in paper mode with every decision visible. It's honest smart-beta — a repeatable tilt toward sound characteristics, not a crystal ball. Open the app and watch the strategy execute, backed by the full research toolkit.
HOW IT WORKS
Open the app. Brain47 shows you the trades — and the research behind them.
EVERY STOCK, SCORED
Brain47 scores every stock across major exchanges on five quant categories — Fundamentals, Quality, Momentum, Risk, and Technical. Fed by SEC EDGAR filings, global fundamentals data, and live price history. A single 0-100 score per stock, refreshed daily.
ONE STRATEGY, LIVE
Brain47 runs a single, rules-based strategy. Every month it tilts a diversified book of around thirty names toward the strongest combination of momentum, quality, and market-implied growth, then rebalances. Disciplined and transparent, running live in paper mode — every decision the consequence of a rule, not a hunch.
YOU WATCH AND UNDERSTAND
Every trade is timestamped, visible, and traceable. Click any position and see the score that triggered it, the Engine's state when it fired, the prose Brain47 generated to describe it. The whole Engine is inspectable, from input data to output prose.
RESEARCH ANY STOCK
Beyond the live strategy, ask Brain47 for a full research report on any stock. It assembles the real data first — a week of news, analyst targets, earnings, multi-year financials from filings, its own score — then writes an institutional-grade note: a bull case, a bear case, the key risks, and a decisive verdict. On demand, and exportable to PDF.
WHY IT EXISTS
Retail investors are flying blind. Hedge funds have Bloomberg terminals, quant teams, and million-pound research budgets. You have Google and a gut feeling.
Brain47 levels the playing field — not with a black-box recommendation, but by showing the actual work. The quant engine scores every stock on the same data institutions use. One disciplined, systematic strategy runs on those signals in public. The Voice Engine explains every position in plain English. You see the score, you see the strategy act on it, you see the outcome — nothing hidden, nothing curated.
0–100
Brain47's proprietary quant model scores every stock across five factors — Momentum, Quality, Risk, Technical, Fundamentals — with weights derived from 30 years of market regimes, not off the shelf
~30 names
A single, rules-based strategy tilts a diversified book of around thirty names monthly toward momentum, quality, and market-implied growth. Honest smart-beta, not a black box. Same approach for every observer, no hidden variants
Every move live
Every holding, every monthly rebalance, every mark-to-market timestamped and visible. The strategy operates publicly, in real time, in paper mode — a genuine forward record, not a backtest
ALWAYS EVOLVING
Brain47 doesn't stand still. Both the quant model and the strategy are continuously researched, stress-tested and refined — versioned, with anything that stops earning its place retired (the scoring model has already dropped factors that failed scrutiny). The premise is that edges decay, so what's worth having isn't a frozen formula — it's the relentless discipline of finding, testing and pruning that keeps the work honest and current.
TRACK RECORD
What The Brain47 Engine has actually done.
Brain47's single, rules-based strategy runs live in paper mode. Below are its actual measured numbers: mark-to-market on the open positions, realised P&L on the closed trades, the win rate across every closed trade, and the Information Coefficient across the full signal-accuracy archive. These are not projections. They are not promises. They are the live readings of the strategy operating in real time.

WIN RATE

Percentage of closed trades that finished with positive P&L across the full simulated trade population.
SHARPE RATIO

Risk-adjusted return per unit of volatility, annualised from the daily NAV series across Brain47's operational lifetime. Industry reference: more than 1.0 is good, more than 2.0 is excellent, more than 3.0 is rare.
INFORMATION COEFFICIENT(40-trading-day horizon)
Computing…
The correlation between Brain47's quant score and the actual subsequent return — the gold-standard quant measurement of whether a signal works. Updated daily via the validation pipeline; full breakdown inside the app on the Strategy Hub.
WHAT THESE NUMBERS MEAN
Active fund managers consistently struggle to beat the broad market — SPIVA reports that around 85 percent of UK active equity funds underperformed their benchmark over the trailing 10 years. Hedge funds average around 7 to 8 percent annual returns net of fees. The S&P 500 has returned around 10 percent annually over the long run.
Against those reference points, an active strategy is considered to have a real edge when its Information Coefficient is more than 0.05, with anything more than 0.10 regarded as strong by institutional standards. A Sharpe ratio more than 1.0 is good, more than 2.0 is excellent, more than 3.0 is rare. Win rates more than 60 percent in active equity strategies are uncommon; most successful strategies operate between 50 and 55 percent, relying on winners being larger than losers.
Brain47's framework is measured against these same yardsticks — openly, in public, with the underlying trade data inspectable. Past performance does not guarantee future results, and the figures above reflect Brain47's simulated portfolio operations only — never a forecast of any user's own outcomes.
FEATURES
What you see when you sign in.
STRATEGY HUB
The live track record — Brain47's one systematic strategy running in paper mode. Mark-to-market NAV by week, month and year; every holding, every closed trade, the win rate, the Sharpe, the Information Coefficient. The forward record being built in public, in real time.
THE 47 SIGNAL
Every stock gets a single 0-100 read from Brain47's own proprietary quant model. Five factors — Momentum, Quality, Risk, Technical, Fundamentals, each a blend of sub-signals — weighted not by guesswork but by what actually held up across 30 years of market regimes, then adjusted for the regime we're in now. Versioned and disciplined: factors that fail scrutiny get cut. A rigorous measurement of a stock's characteristics — the same class as a Piotroski or Altman score — not a directive. The same read for every user, refreshed daily.
TRADE RANKING
Two independent reads on every name, side by side: Company Strength (how good the business is) and Trade Signal (whether the setup is favourable now). A strong company can be a weak trade, and a weak company a strong one — the gap institutions look for, made legible.
AI RESEARCH REPORTS
A full institutional-grade research note on any stock, on demand — grounded in real data Brain47 assembles for you: a week of news, analyst targets and consensus, four quarters of earnings, multi-year financials from filings, the technical read, peer valuation, and its own quant score. Executive summary, five-point bull and bear cases, an objective risk assessment, a decisive verdict — plus the part nobody else writes: what's priced in, what survives scrutiny, and what would change Brain47's mind. Export to PDF.
VERDICT CARDS
A first-person read on any stock — the 47 Signal as ELITE, STRONG, MODERATE, WEAK or VERY WEAK, with the headline factors that drove it. The same card for every observer; no personalisation, no funnels, no upgrade-to-see-more.
