How the Quant System works

Three steps from signal selection to daily monitoring.

Choose your signals

Pick from 12 validated factors across momentum, value, quality, growth, macro, technical, and dividend categories. Each signal has documented historical IC, methodology, and known limitations. No black boxes.

Configure your strategy

Set signal weights, choose your universe (S&P 500, S&P 400, or custom watchlist), define rebalance frequency, and run a walk-forward backtest on data the strategy never saw during development.

Activate and monitor

Rankings refresh daily after market close. Holdings changes notify you by email. Paper trade to validate before going live. Regime state and market breadth are shown on every strategy view.

12 validated signals at launch

Every signal we publish passes Spearman IC validation before appearing in the library. 16 more signals are in development.

📈

Momentum

12-month price momentum and cross-sectional relative strength. Historically one of the most robust factors in equity markets.

⚙️

Quality

Return on equity, earnings stability, and balance sheet strength. Filters for companies with durable competitive advantages.

💰

Value

Earnings yield and book-to-price ratios. Identifies stocks trading at discounts to fundamental value.

🌱

Growth

Revenue and earnings growth trends. Surfaces companies with accelerating fundamental improvement.

📡

Technical

Moving average crossovers and trend confirmation signals. Complements fundamental factors with price-based timing.

💵

Dividend

Relative dividend yield and dividend growth. Captures income-oriented factors with long-term compounding characteristics.

The honest version of backtesting

Walk-forward out-of-sample methodology only — no curve-fitting, no hindsight.

📉

Backtest results — equity curve, drawdown, and signal attribution

Every backtest shows equity curve, maximum drawdown, Sharpe ratio, and which signals drove performance in each period. Walk-forward only: the strategy is tested on data it never saw during development.

Daily monitoring, automatically

Once activated, your strategy runs on its own. You stay informed.
