Brain47Brain47 scores every stock.
Then trades on its own scores.
You watch. You understand.
Brain47 is a quant scoring engine. The Brain47 Engine — a regime-aware, multi-factor adaptive framework — runs across hundreds of simulated portfolios. Every stock gets a 0-100 score across five factor categories. Every signal becomes a trade. Every trade is timestamped, visible, and traceable back to the score that triggered it. Open the app and watch the Engine execute.
HOW IT WORKS
Open the app. Brain47 shows you the trades.
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.
SCORES BECOME TRADES
The Brain47 Engine converts those scores into trades — entries, exits, position sizing — across hundreds of simulated portfolios. The Engine is single, regime-aware, transparent, running live. Every action is the consequence of a score, 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.
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. The Brain47 Engine trades on those scores in public. The Voice Engine explains every position in plain English. You see the score, you see the trade the score triggered, you see the outcome — nothing hidden, nothing curated.

TRACK RECORD
What The Brain47 Engine has actually done.
The Brain47 Engine — a regime-aware adaptive quant framework — runs across hundreds of simulated portfolios. Below are the Engine's actual measured numbers: mark-to-market on the open positions, realised P&L on the closed trades, the win rate across every closed trade in the population, 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 Engine operating in real time.

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